专利说明:

The invention relates to a laminated vehicle glazing unit and more particularly to a laminated vehicle glazing unit incorporating an AMOLED screen.
There are more and more intelligent windshields delivering information to the driver.
The document WO2015041106 proposes in particular an automobile windshield comprising an AMOLED screen (Active Matrix Organic Light Emitting Diode) - between the internal faces of the two glazings, screen arranged at the periphery and masked in the enamelled border opposite F2 it is ie the inner face of the outermost glazing. The AMOLED screen in horizontal position aims to replace the internal rearview mirror to see the rear of the vehicle-classically in the form of a mirror- and is preferably located in the central portion along the upper longitudinal edge of the windshield. It is coupled with a camera at the rear of the vehicle. The object of the invention is to improve this laminated glazing of an AMOLED screen vehicle, in particular an AMOLED screen windshield. For this purpose, the subject of the present invention is a laminated vehicle glazing, in particular a windscreen or side glazing of a road vehicle in particular, comprising: a first glazing, preferably curved, preferably made of mineral glass, preferably tinted, in particular gray or green, with a first main face called F1 intended to be external side of the vehicle and a second opposite main face so-called F2, glazing E1 thickness preferably (especially in the road, for a car) of at most 2, 5mm, even not more than 2mm - in particular 1.9mm, 1.8mm, 1.6mm and 1.4mm - or even not more than1.3mm or not more than 1mm, - a lamination interlayer of polymeric material ( clear, extraclear), preferably thermoplastic, front side F2, of thickness (total) E2, preferably in the road domain, for an automobile) of at most 2.2 mm better than at most 2 mm, at most 1.5mm or even at most 0.76mm, for example e of several leaflets for example 3 leaflets, in particular recessed from the edge of the second glazing (of at most 5mm or even at most 2mm or at most 1mm) - a second glazing, preferably curved (like the first glazing ), preferably made of mineral glass, with a third main face, called F3 on the lamination interlayer side, and a fourth opposite main face, called F4, in particular intended to be on the inside of the vehicle, possibly tinted (or even with an electroconductive layer opposite). F3), of thickness ΕΊ preferably less than E1, even of at most 2.2 mm (especially in the road domain, for an automobile) - in particular 1.9 mm, 1.8 mm, 1.6 mm and 1.4 mm. or even at most1,3mm or at most 1mm, the total thickness of the glazings Ε1 + ΕΊ being preferably (especially in the road domain, for an automobile) strictly less than 4,4mm, even at 3,7mm , at least one - and better the two - first and second glazing being made of glass, the other possibly made of organic material, polymer such as a polycarbonate, - between the face F2 and F face F3, a first organic light-emitting diode display screen called flexible AMOLED screen 3, comprising a set of pixels, the first AMOLED screen comprising a dynamic information display area (central), the AMOLED screen comprising a first flexible support (polymeric glass or even metal material) carrying an organic electroluminescent system (s) ( s) between two electrodes- and AMOLED screen of thickness E3 less than E2 preferably subcentimetric and even at most 0.5mm, AMOLED screen having a front main face facing F3 and a rear main face facing F2, - 1 AMOLED screen being covered by a non-zero thickness of lamination interlayer and preferably within the lamination interlayer, so with a thickness of r non-zero E21 of laminating interlayer between the rear face and F2 and / or with a non-zero thickness E22 between the front face and F3, E2 corresponding to the thickness next to the AMOLED screen (in particular E2> to E21 + E22 and substantially equal to E3), the AMOLED screen is in particular arranged peripherally, - preferably an electrical connection element 4 of the AMOLED screen, with a so-called connectivity portion between the face F2 and the face F3, d E4 thickness less than E2 and preferably subcentimetric, with a front surface front side F3 and a rear surface side face F2, part of connector covered by a non-zero thickness of lamination interlayer and even preferably part of connection within the laminating interlayer (such as the AMOLED screen) with a non-zero thickness E41 of lamination interlayer between the rear surface and the face F2 and with a non-zero thickness E42 (preferably identical to e to the thickness E3) between the front surface and the face F3).
The connector portion is connected (preferably permanent link) to the AMOLED screen and extends (directly) the AMOLED screen towards the edge of the second glazing, and the flexible electrical connection element extending out of the edge of the second glazing (via a so-called outer part).
The connection element in particular is for the power supply and (preferably) / or carrying data signals (simultaneously or sequentially) in particular electrical connection element having one or one of the power supply tracks ("supply lines "In English)" and / or one or more tracks for data signals ("data lines" in English), and electronic components (possibly in particular in the connector part).
The laminated vehicle glazing according to the invention (preferably road vehicle windshield and even automobile) further comprises between the face F2 and the face F3 a first sensor, of thickness E6 less than E2, covered by a thickness of no laminating interlayer E61, possibly within the lamination interlayer, the first sensor being arranged according to the following configurations: (a) between the face F2 and the rear face and / or the rear surface (at the periphery or behind the display area) (b) offset from the AMOLED display and close to the AMOLED display or on a periphery of the AMOLED screen on the front side, (c) offset from the connector portion and close to the part of connectivity or the part of connectivity front side. The AMOLED (transparent) screen is also in the clear glass or is masked by a so-called outer masking layer, opaque, between the face F2 and the rear face of the AMOLED screen (preferably opposite F2 and an enamel layer) and the connection part is also possibly masked by the external masking layer (even when the AMOLED screen is in the window clear), especially between the face F2 and the rear surface.
Currently in automotive windshields, the sensors are arranged in front of F4 in the area of the conventional rearview mirror in the form of a mirror, in the central position of the upper longitudinal edge. The sensors are masked from the inside by a case in front F4, or concealed in the dressing of the vehicle or masked by an enamel reported face F4.
According to the invention, the first sensor (and one or more other sensors) is arranged between the two windows in the vicinity or on the AMOLED screen. The first sensor is no longer salient, is thus protected and can interact with the AMOLED screen. The invention applies equally well when: the AMOLED screen is in the window clear and the connector portion is at the periphery (in particular opaque or weakly transparent) or absent (the connection element absent from the laminate, which can be "Wireless") - the AMOLED screen and the connector part are peripherally (especially opaque or slightly transparent). The AMOLED screen (as the possible connection element) is preferably within the lamination for better mechanical strength. Thus, the laminating interlayer is then present at the front and at the back of the AMOLED screen (as of the possible connection element) which is advantageous compared to an asymmetrical solution in which the AMOLED screen (as the possible connection element) is attached (against or fixed by double-sided adhesive or glue or contact by adhesion) to the face F2 or the face F3.
For windshields, in particular for road vehicles, the glazings are preferably curved and even in two directions, and preferably with two mineral glass panes and even with a PVB lamination interlayer. In this case, the flexible AMOLED screen adapts to the curvatures as the possible part of connectors (and the first sensor on flexible film).
Preferably, the laminated glazing forms a windshield of a road vehicle such as an automobile, a truck, with the first and second domed mineral glass panes and even a laminating interlayer PVB and an AMOLED screen within the laminating (all as the part of connectivity).
According to the configuration a) the AMOLED screen can serve as electromagnetic shielding of the first sensor for the waves coming from inside the vehicle. If it is opaque or weakly transparent, the AMOLED screen is also used to hide the first sensor from inside. A masking box of the sensor is not necessary in face F4. The opaque or weakly transparent AMOLED screen is preferably dark, black in the off state. The first sensor thus masked can be non-transparent (opaque, reflecting etc.) because the simplest or be transparent and even almost invisible (to be in the clear glass). There are transparent sensors that are almost invisible, but making a sensor that is sufficiently transparent can however be restrictive or impossible for certain types of sensors. Thus, some wire sensors are miniaturized or opacified to reduce their visibility, but thin wires can remain visible and alter the transparency of the laminated vehicle glazing. Some transparent layer sensors can also induce optical distortions, especially at the boundary between layer and non-layer areas.
According to one of the configurations a) or b) or c) the AMOLED screen or the connector part can serve as support for the first sensor. They can be added post manufacturing or planned at the time of manufacture AMOLED screen or part of connectors.
The first sensor may be on the periphery of the AMOLED screen (in the same plane or face F2 or F3 or within the lamination) and / or the connector portion (in the same plane opposite F2 or F3 or within the laminating), spaced or attached to the edge of the AMOLED screen or the part of connectivity or even sharing the same support. Thus the first sensor can be integrated in the AMOLED and / or in the connection part.
In (b) or (c) the first sensor may face F3 or F4 in the transparent or surrounding display area, or even in an area to be masked by a case or the vehicle skin.
The outer portion of the connector element may also include a sensor useful for the glazing (windshield, etc.), facing the edge or face side F4. The AMOLED screen may be opaque or transparent. The transparent AMOLED screen (in the window clear in a peripheral zone or not) is preferably defined by a light transmission (TL) of the area of the laminated glazing unit comprising at least 70%. The less transparent AMOLED screen (always intended to be peripheral) is preferably defined by a light transmission (TL) of the area of the laminated glazing unit comprising less than 20% or even 10%.
An opaque AMOLED screen may be defined as having a null TL (for example by adding a layer or paint -metal ...- to the back of the carrier substrate of the AMOLED system).
In a first embodiment, the AMOLED screen is opaque or transparent with a TL light transmission of less than 10% and even less than 5% and / or the connectivity part is opaque or light transmission TL less than 10% and even at 5%. And: in the configuration a), the first sensor is masked from the outside by said external masking layer, or opposite a detection area corresponding to an opening of the external masking layer -or in the configuration b or c) the first sensor is masked from the outside by (an opaque element of) the AMOLED screen or the connector portion and / or by the external masking layer.
In the case of a particular windshield (in particular a road vehicle), this AMOLED screen, preferably in configuration a), may be arranged peripherally and preferably in the central zone of the upper longitudinal edge, in particular in a zone where the width of the outer masking layer is of width L1 greater than its width LO on the driver's side and / or co-pilot.
This makes it possible to arrange an AMOLED screen (opaque or slightly transparent) of greater size, in particular with a greater height H3 (dimension along the vertical). The AM OLED screen may also be closer to the center (closer to the border).
It is also possible to adjust the width W3 or the width H3 so that the first sensor is next to the AMOLED screen in an area of the external masking layer (with opening) or without an external masking layer (but with a low TL accepted )
In configuration b), the AMOLED screen can mask from the outside the first sensor by any means: layer (deposit or added film) on the back, opaque support, dielectric protection material (resin, varnish, film etc) in front back or at the front edge of the display area. In configuration b) ', the connection part can mask the outside of the first sensor by any means: layer (deposition or added film) on the rear face, opaque support, dielectric protection material (resin, varnish, film, etc.) in back or front.
In configuration a), the AMOLED screen can mask the inside of the first sensor by any means: layer (deposit or added film) on the back, electrode, opaque support, dielectric protection material (resin, varnish, film etc) on the rear or at the front edge of the display area. In configuration a), the connector part can mask the inside of the first sensor by any means: layer (deposit or attached film) on the rear face, electrode, opaque support, dielectric protection material (resin, varnish, film, etc.) on the rear or at the front edge of the display area.
Alternatively, the AMOLED screen is in the window clear (peripheral area without backward masking or reduced area B) and: in the configuration a), in the zone with the first sensor and the AMOLED screen or the connection part, the light transmission of the laminated glazing is at least 70%, and in the configuration b) (or c) in the zone with the first sensor and possibly the AMOLED screen, the light transmission of the laminated glazing is from less 70%.
The first sensor is then also transparent even almost invisible (to be in the clear glass).
Preferably, the first sensor is in a scanning zone of one or more wipers of the road vehicle windshield such as an automobile or a truck.
Of course, a plurality of first sensors in (a) and / or (b) and / or c) can be provided, next to one another, on the first glazing unit, or even directly on the AMOLED screen or the part of connectivity, on the same support or not, as a polymeric support or a glass slide.
The first sensor is preferably chosen from at least one of the following sensors: a rain detector (preferably in the wiper zone), typically of size from 100 mm 2 to 600 mm 2, a camera in the visible range -collision, object or person detector in motion or not) or infrared (night vision, anti-collision detector object detector or person in motion or not, for example of trapezoidal shape, and even several cameras of the same type for stereoscopic vision - one or more (typically 6) light sensors, such as a photodiode, typically of size from 1.2x1.4mm2 to 1.4 x 1.8mm2 - a thermometer, thermocouple typically a wire of thickness 0.5mm or less - an alarm sensor (detection of a glazing integrity defect etc), typically of conductive wire size of 12 to 150pms in diameter or by an electroconductive layer (opposite F2 or F3) - a mist detector and linked to a heating element (resistive, etc.) -as an anti-fog, anti-condensation, antifreeze-, typically of size 100-200 cm 2, for example integrated in a rain detector -a sensor forming an antenna, for example a conductive wire typically of thickness 12pm to 0.5mm, for receiving and / or transmitting electromagnetic waves (radio, TV including local communication network such as BLUETOOTH, WiFI, WLAN), in particular within the lamination or embedded in a material polymeric (film etc) - an acoustic sensor (based on a piezoelectric element) - an ultrasonic signal detector preferably on the face F2, (for example based on a piezoelectric element) - a diagnostic sensor (defects in the laminated vehicle glazing including windshield or side glazing) based on an electroconductive layer (full surface) - a control sensor (windshield wiper, etc.), for example IR control or voice control (piezoelectric electric).
In one embodiment, the first sensor or other sensor is a coupling sensor, operatively coupled to the AMOLED screen controlling at least one display parameter and / or image data and optionally face F4.
The coupling sensor can be arranged according to the configurations a) b) or c) or out of laminated glass near the windshield (dashboard, front of the bodywork)
As a display parameter we can cite: -luminosity, contrast, sound volume, zoom, on / off in case of alerts (road accidents, traffic jams, deviation, weather, police message, ...), and / or / off in case of a phone call - image data: selection of information channel, type of information: security, environmental, geographical ...
The coupling sensor is preferably chosen from at least one of the following sensors: a visible or infrared camera (night vision, anti-collision detector object detector or person moving or not in front), the display screen allowing us to see the front.
a fog detector and linked to a heating element, especially in front of R, to clearly see the AMOLED screen
an antenna sensor for receiving and / or transmitting electromagnetic waves (radio, TV, in particular a local communication network such as BLUETOOTH, WIFI, WLAN) for the AMOLED screen - a voice control detector for the AMOLED screen (transducer etc).
Naturally one can have a plurality of coupling sensors.
The term sensor is taken broadly can be one or conductive layers or even any type of electronic or optoelectronic component, photodetectors, or even electromechanical: piezoelectric modules, MEMS (for Microelectromochanical structure). These components can be in any form, for example surface mounted (known as "CMS") or any other type of package or chips. It is possible to use any type of carrier that carries the sensor, for example electrical insulator: polyethylene terephthalate PET, polytetrafluoroethylene (teflon), epoxy, glass fiber, glass wool, polyester, cotton paper or FR-1, -2, - 3, -4, -5, -6, CEM-1, -2, -3, -4, -5 and optionally with a metal layer forming a heat sink.
The sensor support may be transparent especially if it is not masked as well as the sensor power supply conductors. These are tracks of suitable width, transparent electroconductive material: stack of thin layers to silver or transparent conductive oxide layer (ITO, ATO etc.). This support may be a printed circuit board obtained by selective etching of a metallic conductor (copper, etc.)
The first sensor (or any sensor) can be itself (as well as the power supply conductors) on a flexible support (thin) distinct or not the part of connectors, in the same plane or not that said connection part .
There are different types of sensors: capacitive, resistive, inductive.
Of course, it is also preferable to mask the connections and power supplies of the first sensor.
Of course a camera can benefit from a heating sensor to prevent fogging.
The antenna signals (radiofrequency, microwave frequency, HF, UHF) are for example for electronic tolling or from a local communication network such as BLUETOOTH, WIFI, WLAN.
The capacitive sensor operates with an analysis and signal processing unit such as an electronic circuit, or even a chip of at most 1 mm2, also masked from outside and in the vicinity of the first sensor (coupling sensor). We avoid any parasitic capacity.
For example, a sensor comprises three electrodes used for so-called differential measurements or else with at least two electrodes, each electrode and connected to a conductor supplying them (small dimensions relative to the electrodes), conductors for example spaced apart by at most 1 mm. Conductor and electrode may be of the same material, for example with a metal conductive film having a square resistance of at most 10 ohm / square or even at most 5 ohm / square.
For example, a sensor comprises two concentric electrodes, each comprising two sectors of generally annular shape, respectively connected to conductors.
The electrodes and their conductors are also made in a cut conductive layer. Drivers are connected to a treatment set. The conductors between the annular electrodes and the junction ends with the signal supply and processing device are separated from each other by a distance d which is of the order of the size of the sensor. The operating mode is that described previously. The frequency of analysis of the charge of the electrodes is fixed at 33 Hz. To further improve the "signal-to-noise" ratio a peripheral band of the conductive layer is grounded.
The conductive elements forming the sensor and the possible support are for example inserted in the glazing in a zone without internal and / or external masking. They are then essentially transparent materials not to break significantly the visual appearance of the glazing. Preferably, the support and the sensor, constituted in conductive layers applied to this support, are chosen so that they have a light transmission determined according to EN 410 which is not less than 70% and preferably not less than at 80%.
The supports used for the capacitive sensors in particular must fit easily into the glazing. They are preferably as thin as their function allows. If the support comprises only the sensor, a flexible film for example polyethylene terephthalate said PET, coated conductive layers may be used. In this case the thickness can be particularly low, of a few hundredths of a millimeter. The insertion of a support is preferably made from an edge of the glazing.
The combination of different functional units in the same glazing, all electrically powered, inevitably generates fields that can disrupt the operation of the capacitive sensor. In order to avoid or at least minimize these parasitic influences, the capacitive sensor is advantageously constructed so as to make the signals emitted by the sensor more discriminated. For this purpose the sensor comprises a set of two electrodes located in the vicinity of one another. To avoid that the establishment of multiple elements, including conductors connecting the sensor to a processing unit located outside the glazing, complicates the structure and assembly of the glazing, these conductors are advantageously formed in the same layer as that electrodes of the capacitive sensor, and thus also offer the same transparency if necessary. Possibly other conductors can also be used, including very small diameter son and therefore little discernible.
The transparent electrical conductive products that can be used according to the invention to form the sensor are well known in the glass field. They consist of sufficiently thin layers of conductive oxides, or of the latter metal layers arranged in sets of protective dielectric layers.
Among the most conductive oxide layers (TCO), in particular indium oxide doped tin oxide (ITO) -based layers. These layers under thicknesses meeting the condition of transparency, allow to reach resistances of less than 50Ω / α and preferably less than 30Ω / α and particularly less than 20Ω / a.The electrical resistance of the layers is necessarily function of their thickness. An increase in the thickness makes it possible to reduce the resistance but runs up against the necessity to preserve a good transparency. For ITO type layers, an acceptable level of absorption corresponds to layers whose thickness does not exceed 300 nm, and preferably 200 nm.
All the components included in the curved glazing must be able to support these curvatures, hence the need to use sufficiently flexible sensor supports. Moreover, when the supports of the sensors have a not insignificant thickness for example of at least 0.15 mm and even at least 0.2 mm, it is preferable to facilitate assembly, to arrange these supports in a corresponding reserve practiced in a lamination interlayer sheet of similar thickness thus constituting a kind of frame for the support.
In one embodiment, the first sensor (and its power supply) may be an insert, in particular bonded, on the rear face and / or the rear surface or even on the front surface or on the face F2 - for example a or electroconductive wires (embedded or not in a resin) or a conductive element (electroconductive layer) on a flexible polymeric support (tq PET, PC etc).
In one embodiment, the first sensor (and its power supply) is on the face F2, on the external masking layer opposite F2 or in the detection area (opening (s) of the external masking layer).
In particular, the outer masking layer, preferably in enamel, is opposite F2 and in particular the first sensor is electroconductive enamel on the first masking enamel and even masked by the inner masking layer. In particular, the internal masking layer, preferably in enamel, is opposite F3 and in particular the first sensor is electrically conductive enamel on this layer.
In a second embodiment, the first sensor (and its power supply) comprises a conductive layer at the front or rear of the AMOLED screen or the connector portion, or a conductive layer on the face F2 or face F3.
The first sensor may be capable of creating a harmful local pressure on the rear face (or front) of the AMOLED screen, any variation of even very small thickness often creating visible deformation in reflection, for example by its thickness E6 ( maximum) and its design (use of room (s) reported rather than layers) can provide:
- To adapt the thickness of the first flexible support of the AMOLED display - a compensation in thickness on the whole surface facing either side of the sensor (s) - or shift the first sensor out of the AMOLED zone.
In one embodiment, the laminated vehicle glazing unit comprises, on the face F2 or on the face F3 or F4, a transparent electroconductive layer forming an antenna: if on the face F3 opposite the front face, or if on the face F3 absent from the zone opposite the front face, especially in the peripheral area to the information display area and even to the AMOLED screen and the external masking layer.
It is possible to have a zone on the face F4 which is a sensor formed from a transparent electroconductive layer, for example a transparent conductive oxide (ITO for example alone or in a stack). For example, the sensor is an antenna element (for signals coming from inside and / or from outside).
This local layer can be heating and anti-fogging opposite the display area. This layer can also be at the periphery and carry a sensor in an area covered with a housing or under the trim
According to the invention, the sensor may be masked or in a viewing zone and may be associated with one or more electronic components (amplifier, decoder, power supply cable, etc.), preferably outside the viewing zone (case in front of F4 or below it). trim or along the edge of the glazing or in the dashboard).
Preferably, the outer masking layer is enamel and F2 face behind the AMOLED screen and the other possible AMOLED screens. In the off state, it is possible not to distinguish the AMOLED screen area from the masking area further back. It is possible to adapt the color of the external masking layer (in particular enamel, face F2) accordingly.
In one embodiment, the AMOLED screen is transparent and in the clear glass or in that the AMOLED screen (transparent or opaque) is masked by a so-called external masking layer between the rear face of the AMOLED screen and the face F 2 (, and / or the electrical connection element is masked from the outside, in particular by a so-called external masking layer between the rear surface and the face F 2 and the technical edge or edges of the AMOLED screen as well as the element connection are masked from the inside by a so-called internal masking layer opposite F3 or F4
In one embodiment, the laminated glazing comprises a plurality of AMOLEDS screens, especially at the periphery of the same longitudinal or lateral edge.
In a preferred embodiment, the AMOLED screen covers at most the entire peripheral area visible by the driver (or co-pilot if AMOLED screen on his side) in the windshield of road vehicle (automobile) to the edge of the central area of Transparent vision and more precisely: - up to the upper edge of the central zone of transparent vision if the AMOLED screen is arranged horizontally on the driver's side (or co-pilot if AMOLED screen on its side) along the upper longitudinal edge driver (or passenger) - to the lower edge of the central clear vision zone if the AMOLED display is horizontally arranged horizontally on the driver's side (or co-pilot if AMOLED screen on its side) along the lower longitudinal edge of the driver's side (or passenger) - to the upper edge of the central zone of transparent vision if the AMOLED screen is arranged at the top horizontally or vertically in the central zone of the upper longitudinal edge - to the left edge of the central transparent vision zone (respectively right) if the AMOLED screen is arranged vertically to the left, preferably on the driver's side (preferably right-hand side, preferably on the co-pilot side) of the left lateral edge, preferably in the lower part (lower half of the lateral edge) to be wider.
It is the same for the said other AMOLED screens - if opaque or weakly transparent, preferably masked by the external masking layer, preferably opposite F2-.
The upper, lower, lateral (left and right) edges (or boundaries) of the transparent central vision zone are defined in particular by a regulation standard. For example for a windshield of a road vehicle, automobile, this is the reduced area B defined according to the European standard UN-ECE R43 Annex 18, in particular page 133 and § 2.4. The upper limit of the central zone of transparent vision is preferably defined from an angle between the horizontal and 7 ° from a reference point (the driver's eye, eye at height Z with respect to vehicle seat with Z = 665mm for a large driver or Z = 589mm for a small driver From the relevant edge of the laminated glazing including road vehicle windshield, the following distances are defined: - h1 distance between the upper edge and the upper limit of the peripheral vision area of the driver (or co-pilot if AMOLED screen on his side) in the vehicle, preferably at least 15mm and even at least 50 or 90mm - h'1 distance between the edge lower and lower limit of the peripheral vision area of the driver (or co-pilot if AMOLED screen on his side) in the vehicle preferably at least 40mm and even at least 100 or 200mm - h4 distance between the edge l attral (left or right) and the lateral limit of the peripheral zone of vision of the driver (or co-pilot if AMOLED screen on his side) in the vehicle preferably of at least 15mm and even of at least 20 or 40mm.
Outside the area of the AMOLED screen (and / or said other AMOLED screens), an external peripheral masking layer (on the face F2) can be formed, such as enamel, singing up to h1, h'1, h4 by exceeding example of the (predetermined) vision zone of at most 2cm as conventionally.
According to the invention it is possible to increase the width of the external masking layer in a manner to hide the AMOLED screen (and the said one or more other AMOLED screens) and at most up to the limits of the central transparency zone. External masking is therefore possible from the reduced viewing zone limit B to the edge of the (first) glazing. Depending on the relevant edge of the laminated glazing including road vehicle windshield, the following distances are defined:
- h2 distance between the upper edge and the upper limit of the central transparency area driver side (or co-pilot if AMOLED screen on its side), preferably at least 120mm and even more than 150mm or 200mm or 220mm, the AMOLED display being above said upper limit and even any other AMOLED screen (s)
- h'2 distance between the lower edge and the lower limit of the central area transparency driver (or co-pilot if AMOLED screen on its side) preferably at least 120mm and even more than 150mm or 300mm and the AMOLED screen being below the lower limit and preferably any other screen (s) AMOLED
- Ha distance between the upper edge and the upper limit of the central transparency area in the central part (for AMOLED screen in central position), preferably at least 180 mm and even at least 250 mm or 300 mm and the screen AMOLED being between the edge and the upper limit as well as preferably any other AMOLED screen (s) - h5 distance between the lateral edge (left or right) and the lateral limit of the central zone driver side transparency (or co-pilot side if AMOLED screen on its side) preferably at least 80mm and even more than 120 or 150mm, and the AMOLED screen being between the lateral edge and said lateral limit and preferably the any other AMOLED screen (s).
The height h6 of the reduced zone B in the high position (between the potentially opaque zone and the most central zone A) can be from 60mm to 90mm. It can be used for an AMOLED (fairly) transparent screen (which can go up in the potentially opaque zone). Preferably the outer masking layer is higher than the AMOLED screen. The height h'6 of the reduced zone B in the low position (between the potentially opaque zone and the zone A plus the central one) can be between 60mm and 90mm. It can be used for an AMOLED (fairly) transparent screen (which can go down in your potentially opaque zone). Preferably, the external masking layer is lower than the AMOLED screen.
The outer masking layer area is preferably at least as large as the surface of the AMOLED screen, preferably a little larger:
for example at least 5 mm on each side of the AMOLED screen and / or for example at least 5 mm below the most central edge (bottom edge if position at the top of the AMOLED screen, bottom edge if position at the bottom of the AMOLED screen)
I
The outer masking layer may be a solid area (flat) extended by a discontinuous network pattern (geometric, round, square, rectangular etc.) preferably gradient in the direction of the center of the laminated glazing (windshield). The gradient can be up to 15mm wide and even at most 10mm wide and at least 3 or 5mm wide. The gradient may be in the area of the lower longitudinal edge of width of at most 30mm and even at most 25mm and at least 10 or 15mm. Preferably the AMOLED screen is not behind the gradient but behind the solid zone. At the limit only the gradient can exceed the AMOLED screen.
It is possible with several zones of enlarged masking along a reference edge or distinct edges and even an enlarged mask area dedicated for each AMOLED screen.
The laminated glazing including a windshield of a road vehicle (automobile) of rectangular shape can be: -width (horizontal dimension) Lp of at least 1200mm and at most 1850mm and preferably 1350 to1550mm. - height (vertical dimension) Hp of at least 800mm and at most 1400mm and preferably from 950 to 1050mm.

The present invention will be better understood and other advantageous details and characteristics of the invention will become apparent on reading the examples of laminated vehicle glazings according to the invention illustrated by the following figures: FIGS. 1, 1 ', 1a, and 8 are each a diagrammatic front view of a windshield with an AMOLED screen of a motor vehicle, viewed from the inside - FIGS. 1a, 1a, 2a, 2b are schematic front views and detail diagrams. A windshield with an AMOLED display of a motor vehicle, inside view - Figures 2, 3, 4, 5, 6, 7 are schematic sectional and partial views of a windshield with AMOLED screen a motor vehicle, interior view.
It is specified that for the sake of clarity the various elements of the objects represented are not necessarily reproduced on the scale. For simplicity, the glazings are not represented curved nor the flexible elements in the curved lamination by adapting to this or these curvatures (in two dimensions) glazing.
Figure 1 is a partial schematic view of the inside of a windshield with AMOLED screen 100 of a motor vehicle.
The windshield 100 comprises a central clear view area (central portion of the inner glazing 1 'and therefore face side F4 14) and an outer masking peripheral frame 5, the lower longitudinal edges 15a and 15b high, 15c left and right side 15d, frame hiding here the back of the AMOLED screen 3 opaque or weakly transparent (not transparent enough to be in the clear glass). The external masking layer 5, opposite F2, thus hides a view of the outside of the vehicle AMOLED screen 3 (and its connector not shown here, preferably in the laminated). The enamel 5 has the primary function of hiding, seen from the F1 face, the adhesive bead solidarisant the final laminated glazing to the body berry. The AMOLED screen is arranged in a central position of the top longitudinal edge 15b horizontally and is rectangular. It is (all or part) in a so-called enlarged zone whose width (vertical dimension) L1 of the enamel is greater than the width LO adjacent (for example to the left) serving for conventional masking and even co-pilot side.
For example, the horizontal dimension or width W3 is at least 120mm and even up to 250mm. The vertical dimension or height H3 is at least 75mm. The AMOLED screen 3 is here lowered to the lowest of the enlarged peripheral zone. Its low edge 34 is near or on the border of the flat enamel 51 (solid zone) rather than on the border of the eventual zone with enamel patterns for example of width of at most 15mm. Its high edge 34 'can be as high as possible (at the edge of the vision zone in the cabin), typically at least 15mm and better at least 70mm. It depends on the design of the windshield (size, inclination, clear vision desired by the manufacturer).
The edges 53, 53 'of the enlarged zone of enamel 50 may exceed lateral edges 33 and 33' for example of at most 2 cm or even 1 or 0.5 cm (limit of the solid zone). In the off state, the AMOLED display is dark and even does not stand out or barely from the enamel background 5 (protruding on the sides). The enamel color can be adapted accordingly. Preferably the enamel is opaque and dark. The AMOLED screen is here in a peripheral zone distinct from the transparent central zone called zone A ZA (the most central and in two parts, in quadrilateral) or the reduced zone B Zb (in dotted lines).
A first sensor rain sensor (here not visible) is behind the AMOLED screen within the lamination in the area swept by a windshield wiper.
On the AMOLED 3 display on, you can see the central vision of the rear of the vehicle and preferably the side visions of the vehicle The AMOLED display can have the vision function of the rear. It can also have other functions such as: telephone mode, television mode, display of environmental data or on the road (maps, GPS etc.) or on the vehicle, simultaneous display on one or more screen areas (for example at the way of a mobile phone screen).
In a variant that is not shown, the AMOLED screen is on the longitudinal edge at the top of the driver's side. It is higher but may be wider than in the central zone and protrude in the central zone (excluding the protruding zone of enamel).
In a variant that is not shown, the AMOLED screen is on the lower longitudinal edge on the driver's side in the viewing zone. It may be wider than in the central zone. In a variant that is not shown, the AMOLED screen is on the low side edge on the driver's side and is arranged vertically at the lowest point in the viewing zone.

The connection element 4 is a flexible printed circuit (in English: "Flexible Printed Circuit" - FPC) capable of implementing 2560 X 1600 pixels (AMOLED screen). The FPC 4 could also advantageously be of the same width as the AMOLED screen 3, so as to facilitate the insertion of the two elements into the lamination interlayer, preferably of polyvinyl butyral (PVB slightly set back from the glazing edges). .
The inner glass 1 'has a notch 11'. The dimensions of the notch 11 'are adapted to the FPC 4: - width of the notch 11' greater than or equal to that of the FPC 4; depth of the notch 11 'greater than or equal to the thickness of the FPC 4 preferably to prevent the FPC 4 is visible from the outside in case of apparent edge.
In practice the depth of the notch 11 'is between 1.5mm and 2mm. The area of the notch 11 'is substantially free of lamination interlayer.
Between the face F2 and the rear face of the AMOLED screen 3 can be placed sensors including conductive layer or electrically conductive son in particular a rain sensor 72 for example capacitive type in the area of the windshield wiper or two cameras (stereoscopic vision) 71, 71 'for the visible or infrared on the face F2, more precisely each glued in an opening (detection area) of an enamel opposite F2.
Alternatively or cumulatively one or sensors 70 can be placed between the face F2 and the rear surface 41 of the FPC, in particular on or integrated in the FPC 40 before mounting (and even before coating). A predetermined area on the FPC is provided for this purpose for example by expanding the FPC.
Alternatively or cumulatively, one or more sensors 70a may be placed next to the FPC 40, in the same plane and of the same thickness preferably, and even use the notch 11 'to extract a flexible flexible carrier carrying the sensor or sensors 70a.
Alternatively or cumulatively, one or more sensors 73, 75 may be placed near and on the periphery of the AMOLED screen 3 (here on the left side and below), on the face F 2 or on the face F 3 or within the lamination in particular any relatively thick element. This or these sensors 73, 75 are masked by the external masking layer (or not if they are invisible, and then in the clear glass or in front of the bottom of the outer masking layer with optional opening forming detection area) . It can be cameras or photodiodes.

Alternatively or cumulatively, one or more sensors 70 may be placed between the face F3 and the front surface of the FPC, in particular on or integrated in the FPC before mounting (and even before embedding). A predefined area on the FPC is provided for this purpose for example by expanding the FPC. This sensor can then be masked by an enamel opposite F3 or F4 or an opaque overlayer on the FPC 40.
Alternatively or cumulatively one or sensors 70a can be placed next to the FPC, in the same plane and of the same thickness preferably and even use the notch 11 'for a flexible flexible support carrying sensors 70a. This sensor can then be masked by an enamel opposite F3 or F4 or an opaque overlayer on the FPC 40.
Alternatively or cumulatively, one or more sensors 75a, 75b may be placed near and on the periphery of the AMOLED screen, on the face F2 or on the face F3 or within the lamination, in particular any relatively thick element masked by the layer external masking (or not if they are invisible).

Figure 2 is a schematic sectional and partial view of a windshield 200 with AMOLED screen of a motor vehicle, inside view.
The windshield 200 comprises: a first glazing 1, with a first main face 11, called F1, intended to be on the outside side of the vehicle, and a second opposite main face 12, called F2, preferably having a thickness E1 of at most 2.5 mm, in particular a preferably dyed silica-glass float glass sheet, with a glass thickness of 2.1 mm, such as a TSA glass of the Applicant Company - a laminating interlayer made of polymeric material 2, face-side F 2, of thickness E2 preferably at least 0.76mm as polyvinyl butyral (PVB) - a second glazing 1 ', with a third main face 13 so-called F3 lamination intermediate side 2 and a fourth opposite main face 14 so-called F4, to be rated the interior of the vehicle, preferably having a thickness ΕΊ of at most 2.2 mm, in particular a sheet of float glass with a thickness of 1.6 mm of glass thickness, for example stained like a TSA glass of the Applicant Company, - between the face F2 and the face F3 and within the lamination interlayer, an organic light-emitting diode display screen, comprising a set of pixels, said AMOLED screen 3, flexible, the AMOLED screen comprising a dynamic information display area 32 ', of thickness E3 less than E2 and preferably subcentiometric, AMOLED screen having a front main face 32 facing the face F3 and a rear face 31 facing the face F2, AMOLED screen is arranged at the periphery, - within the laminating interlayer an electrical connection element 4 of the AMOLED screen. The OLED screen 3 is sandwiched between the outer glass sheet 1 and the inner glass sheet 1 '. It has a display area 32 'framed by one or two, three or four technical edges) in narrow peripheral fringes 34, 34' of width generally of at least 0.5 mm (and preferably less than 1 cm). ). The AMOLED screen 3, flexible and directly extended to an edge of the glazing, by the connecting element 4 which is connected to it and extends out of the lamination.
It is powered by an electrical connection element 4 of the AMOLED screen 3 which comprises: a flexible part called connection 40 between the face F2 and the face F3 within the lamination interlayer with a front surface 42 on the front side F3 and a rear surface 41 on the face F2, of thickness E4 less than that E2 of the lamination interlayer connected to the AMOLED screen and extending the AMOLED screen towards the edge of the second glazing 1 ', - extended out of the edge of the second glazing via a so-called outer portion 45 curved and fixed by gluing (opposite F4 without extending to the display area 32 'via a portion 47 terminated by its connector 8 in a zone accessible at the time of assembly The connection element 4 is a flexible printed circuit (in English: "Flexible Printed Circuit" (FPC) capable of implementing 2560 × 1600 pixels (AMOLED screen) .The FPC 4 could advantageously be same width as the AMOLED screen 3, so as to facilitate the insertion of the two elements in the lamination interlayer (a little behind the glass edges).
The inner glass 1 'has a notch 11'. The dimensions of the notch 11 'are adapted to the FPC 4: - width of the notch 11' greater than or equal to that of the FPC 4; - Depth of the notch 11 'greater than or equal to the thickness of the FPC 4 preferably to prevent the FPC 4 is visible from the outside in case of apparent edge.
In practice the depth of the notch 11 'is between 1.5mm and 2mm. The area of the notch 11 'is substantially free of lamination interlayer. The AMOLED screen 3 has for example a thickness E3. The connector portion 40 may be less thick. It is optionally covered or coated with any material to increase (if necessary) the thickness E4 to a value substantially equal to E3. If E4 equals 0.4mm, E3 is 0.38 to 0.40mm. For example, for the lamination, a central sheet 22 of 0.38 mm with a reserve for accommodating the AMOLED screen and the connector part and two outer sheets 22, 23 of 0.17 mm or 0.38 mm are used. One of the outer sheets may be thicker eg 0.76mm.
We can have more than 3 sheets (if insertion of a polymeric film like a PET etc) or for more mechanical protection.
When the AMOLED screen has a thickness of at most 0.15 mm or even at most 0.2 mm, it is possible to remove the central leaflet at assembly.
The first glazing (outside) 1 comprises an outer masking layer 5 facing F2, opaque, black enamel preferably, -with an edge 51 towards the center of the windshield - and an edge 52 edge edge of the glazing 15 for example at most 3 or 1mm from the edge 15.
It hides not only the adhesive bead 7 'of the gasket 7 "but also the AMOLED screen 3 (opaque or weakly transparent), the connection part 40 and the non-glazed part 45 of the FPC and the part 47 and its connector 8 .
The outer masking layer 5 is preferably a solid area (a solid area) rather than a pattern network. Beyond the edge 51 it can be extended by a pattern of patterns (of the same material) for example gradient over a width of at most 15mm and even 5mm and even greater if the edge 15 is the lower longitudinal edge.
The second glazing T (inside) comprises opposite face F4 an internal masking layer 6 opposite F4 (or alternatively F3), opaque, preferably black enamel, with an edge 61 towards the center of the windshield-an edge 65 notch side.
This internal masking layer 6 masks the entire surface of the connector portion 40, in particular that which is in the viewing zone (outside the zone with trim or possible housing). It can be wider than the connection part. . This internal masking layer also hides from the inside the technical edges 34, 34 'of the AMOLED screen. It may exceed for example of at most 10mm opposite the lamination interlayer around the edges of the technical edges to hide flaws.
When the internal masking layer 6 is thus on the periphery of the AMOLED screen 3, an opening 63 (masking or post-fabrication of the layer) has thus been formed, leaving the display area 32 'visible.
It can also exceed more widely technical edges to be of width (almost equal) to that of the external masking layer 5 on either side of the AMOLED screen (and / or the connector portion).
The internal masking layer 6 is preferably a solid area (a flat area) rather than a pattern network. Beyond the edge 61 it may be extended by a pattern of patterns (of the same material) for example in gradient on a width of at most 15mm and even 5mm and even greater if the edge of the notch 11 'is the lower longitudinal edge.
The sensors may preferably be placed in the wiper scanning zone and / or: on the face F2, behind the AMOLED screen, for example a sensor 71 which is capacitive and for example a rain detector and sensor 72 which is a camera facing a local aperture 53 of the masking layer 72 - and / or on the face F2, behind the connector portion 40, for example sensor 70 which is which is capacitive and - and / or on the face F2 in a transparent area (glass clear), sensor 73 for example a camera, or a possibly transparent sensor if necessary, - and / or on the face F3 in a transparent area (clear glass), sensor 74 by example a camera, or a possibly transparent sensor if necessary in particular transparent electroconductive layer or wire (s) sufficiently fine.
The sensor 71 or 70 may comprise an electroconductive layer such as a conductive enamel on the enamel at F2.
Sensor supply conductors may exit through slot 11 'or nearby.
A sensor 76 is on the face F4 in the field of vision, on the enamel 6 in F4, preferably it is in a housing. It serves for example antenna element for signals used by the AMOLED screen. It can be a conductive enamel on enamel 6. It may be a transparent or opaque layer under the enamel 6 (no masking box needed) Other sensors for the AMOLED display may be at the front of the vehicle or in the dashboard.
The sensors in particular electroconductive layer or son may be covered by a polymeric film (adhesive) such as a polyimide, a PET or a varnish to be isolated PVB.
A sensor can affect one or more AMOLED screen display settings: luminance, contrast etc. depending on the day or night or depending on the climate (snow, rain, fog). A sensor can be used for a GPS function of the AMOLED display. The rain detector can be coupled to the AMOLED screen in particular to indicate a reduced speed limit (in addition to operating the ice wiper)
A sensor can estimate the distance to an obstacle or car in the front and in particular to alert the driver to a short distance too short via the AMOLED screen. The camera (s) in the visible (73 or 74 preferably) are also used to detect in particular fog to indicate a reduced speed limit via the AMOLED screen.
The camera (s) in the infrared (preferably 73 or 74) are used at night to alert via the AMOLED screen for example the presence of animals or bicycles etc. A photodiode is used for example to assess the natural illumination to adjust the luminance of the AMOLED screen.
A temperature sensor can be used to control the operating parameters of the AMOLED display.
Figure 2a is a schematic front view and detail of a windshield with AMOLED screen of a motor vehicle, view on the inside.
It illustrates the possible extent of the internal masking layer 6 on either side of the technical edges 33, 33 ', 34, 34' of the AMOLED screen here arranged horizontally along an upper longitudinal edge, in position central or not. - Side edges 64 and 64 'preferably exceeding at least 3mm and - low edge 61 preferably exceeding at least 3mm.

sensors 70, 71, 71 ', 72 (in dashed lines) behind the display area 32' of the AMOLED screen or the connector portion 40 of the PFC 4 here with a width equal to the AMOLED screen -a sensor 74 opposite F3 (or F3) in a transparent area beyond the edge 61 (and the enamel opposite F2).
It is also possible to place one of the sensors behind the internal masking layer 6 (and in front of the external masking layer with a local opening if necessary): - sensor 73 'on the lower edge 61, on the face F3 or F2 - sensor 75 on the edge lateral (here left) 64, on the face F3 or F2.
One can even provide one or sensors on the technical edges of the AMOLED screen, possibly sufficiently wide for this purpose.
The internal masking layer 6 is alternately a strip of a given width with an opening for the AMOLED screen, -band along the upper or lower longitudinal edge, the horizontally arranged AMOLED screen being on the driver and / or co-pilot side from the left or right side edge, the AMOLED screen arranged vertically on the driver's side and / or co-pilot.

One can even provide one or sensors on the technical edges of the AMOLED screen, possibly sufficiently wide for this purpose.
Figure 3 is a schematic sectional and partial view of a windshield 300 with AMOLED screen of a motor vehicle, inside view.
Windshield 300 differs from windshield 200 first in that the inner masking layer faces F3 instead of face F4.
The windshield 300 differs from the windshield 200 also in that the sensors 71, 72,70 masked face F2 are now on the rear face 31 or the rear surface 41, for example on a polymeric film such as a PET. The sensor or sensors may comprise in particular an electroconductive layer deposited on the polymeric film with possibly an interposed barrier layer. They can also be covered by a polymeric (adhesive) film such as a polyimide, a PET or a varnish to be isolated from the PVB.
The sensor 76 may be invisible or almost invisible, for example includes an ITO layer or other transparent conductive oxide.
Figure 4 is a schematic sectional and partial view of a windshield 400 with AMOLED screen of a motor vehicle, inside view.
It differs from the windshield 200 in that the internal masking layer 6 is replaced by an opaque (opacified) film 6 'of polyethylene terephthalate (PET) which can be adhered to the entire screen AMOLED 3 and FPC 4 from its premounting for storage, or be part of a film that has been adhered to with this preassembled assembly, a film which can then optionally eliminate an unwanted part pre-cut before assembly windshield.
The opaque film 6 'constitutes: a masking of the FPC 40, opaque or weakly transparent, and of the junction between the PVB 22 (central part) and the AMOLED screen 3, which may comprise irregularities and faults, as well as a masking 61 ', 62' of the technical edges 34 of the AMOLED screen 3, seen from the inner side of the windshield.
The opaque film 6 'may also be an opaque extension of the transparent polymeric material covering the AMOLED screen, i.e., to be an integral part thereof.
The opaque film 6 'may alternatively or cumulatively be an extension of the polymeric material covering the FPC, that is to say, be an integral part thereof.
Furthermore, the face F3 is provided with an electroconductive layer 9 and possibly a current supply 9 'for it; this layer may consist of a stack reflecting solar radiation, silver or other, or a coating / heating stack provided for this purpose with its current supply 9 '. It can be covered directly with a masking of the technical edge of the AMOLED screen mentioned above.
The sensors 71, 72, 70 masked on the face F2 are now on a polymeric film 77 transparent or not as a PET laminated in the PVB between face F2 and rear surface 31 and rear face 41 and preferably outgoing notch side (and even folded to This sensor-carrying film (PET) is in the same plane as the AMOLED screen, in the vicinity and even leaves the notch 11 '.
The sensor 74 'on the face F2 in the viewing zone is a zone of the electroconductive layer 9. For example, it forms an antenna element for the exterior (gutting, etc.). Other areas of the electroconductive layer 9 may form a zone sensor 76a in front of the display area, for example antenna element for the interior - zone 76 'facing the front surface 42 masked example element d indoor antenna or fog detector. 76a and 76 'are transparent sensors.

For aesthetic reasons the electroconductive layer is absent at least in the area 91 facing the display area 9. This opening 91 may be larger (towards the left of the drawing) in order to remove the coloration due to the reflection of layer. It can also increase the TL in a clear window area (without enamel).
Figure 6 is a schematic sectional and partial view of a windshield 600 with AMOLED screen of a motor vehicle, view on the inside.
It differs from the windshield 200 in that the AMOLED screen 3 is placed in a transparent vision area of which no external masking layer 6 behind.
However, the masking of the outside of the technical edges 34, 34 '(and even the PVB 22) by the external enamel layer 5.51 can be accepted. As a result, the enamel layer 5 may have an opening 53 facing the AMOLED screen area. And masking the inside of the technical edges 34, 34 '(and even the PVB 22) by the inner enamel layer 6,61 can be accepted. Suddenly the enamel layer 6 may have an opening 63 facing the AMOLED screen area.
The sensors on the F2 side facing the AMOLED screen area have been removed or are sufficiently transparent. One or more sensors 70, 72 'can be added behind the still masked FPC 4 (hardly transparent enough). sensors 71, 70 'integrated in the AMOLED screen or the FPC 40 can be provided.
