    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 an outer portion (of thickness E'4 less than E4 beyond the edge of the second glazing), which is curved (flexible) and said end portion. The connection element in particular is for the power supply and (preferably) / or carries data signals (simultaneously or sequentially) in particular electrical connection element having one or more power supply lines ("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 glazing according to the invention comprises, on the face F4, an interface box connected (by a male-female connection system by plugging, clipping, snapping or any connection preferably removable) to the terminal part of the electrical connection element (adhesive bonded), enclosing one or more electronic components (on a printed circuit board of PCB type for example), preferably control) of the AMOLED screen (and / or exchange of data with the AMOLED screen), the interface box being further connected (at least) with a wire system (fi) or cable etc) of power supply, in particular by a female male connection system by plugging, clipping , snap or any removable connection preferably, in particular outside the glazing and extending out of the face F4 of the glazing (along the edge).
    The glazing unit according to the invention comprises, on the face F4, an interface box connected to the terminal part of the electrical connection element and enclosing one or more electronic components including control of the AMOLED screen, the housing of interface being (possibly only) further connected with a wired power supply system including on the same edge or on a separate edge of the interface box.
    The interface box makes it possible to manage less wires or cables to facilitate the assembly disassembly and the exchange of data between AMOLED screen and a local network, a telephone, a computer. It can be used to separate connectors and electronic control interface from the AMOLED display.
    The wired power supply system therefore preferably does not feed directly on the terminal part.
    The housing can be moisture proof
    According to one embodiment, the interface box can also be connected to a wired system (cable, etc.) for transporting data signals (to a "busdriver" in English), for the AMOLED screen, in particular by means of a data transmission system. male female connection, by plugging, clipping, snapping or any removable connection preferably, in particular outside the glazing and extending out of the face F4 of the glazing (along the edge). The wired data signal transport system for the AMOLED display may be on the same edge of the interface box or on a separate edge as for the wired power supply system.
    The housing can be parailelipedic and / or: -with a longitudinal edge oriented towards the edge of the second glazing connected to said connector of the wired power supply system - with a lateral edge connected to said connector of the terminal part - and even with another edge side connected to said wired system connector for the data.
    The housing may be parailelipedic and / or: -with a longitudinal edge oriented towards the edge of the second glazing connected to said connector of the wired power supply system and connected to said connector of the terminal part or even connected to said connector of the wired system for the data .
    The housing can be paraileliped and / or: with a longitudinal edge oriented towards the edge of the second glazing possibly connected to said connector of the data wire system with a lateral edge connected to said connector of the terminal part with another lateral edge connected to said connector of the wired power supply system.
    In one embodiment, the interface box has a bottom that carries or is a printed circuit board.
    The interface box may further be connected to a wired data signal transport system for the AMOLED screen that extends out of the pane (preferably at the periphery (and under a trim, plastic upright etc.).
    The housing may include an antenna signal receiver. The antenna signals (radiofrequency, microwave frequency, HF, UHF) are for example for electronic toll collection or from a local communication network such as BLUETOOTH, WIFI, WLAN carrying data for the AMOLED screen, especially for his order.
    The housing can be mounted on the end portion or is adjacent to the end portion and connected at one end of the end portion and against or fixed (by gluing as a pressure-sensitive double-sided adhesive) to said face F4.
    The bottom of the housing may correspond to an area of the surface of the end portion.
    The interface box is made of plastic, in particular with additional and / or metallic electromagnetic shielding means with a communication window for receiving signals.
    The interface box is preferably masked, in particular behind a trim of the vehicle, at a distance d from the edge of the second glazing of at most a few cm, for example less than 5 cm. 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). The connection element can be "wireless". However, a flexible (flat) connector according to the invention is preferred for transporting the power and / or data signals to one or more wireless connectors (inductive or capacitive). The electrical connection element preferably of submicron thickness E4 substantially equal to E2 and of thickness E'4 less than E4 beyond the edge of the second glazing, is preferably curved and against or better fixed by bonding in front F4 without extending to the display area. The connection element is advantageously partially covered or coated, if necessary, with any material to increase the thickness to a value substantially equal to that of the AMOLED screen. The connection element is preferably a flexible printed circuit ("fpc" in English). The connection element is preferably capable of addressing a large number of pixels. The flexible electrical connection element (in particular the connector portion) may be of a width that is less than or substantially equal to that of the AMOLED screen, typically 50 mm wide for AMOLED widths (horizontal dimension) of at least 100 mm. and even more than 150mm. Large (large) screens can have multiple flexible electrical connection elements preferably on the same edge of the AMOLED screen.
    The distance between the termination of the electrical connection element and the edge of the second glazing is sufficiently large for this termination to be accessible during assembly or disassembly. The total length (unfolded) is adjusted for the connection element is folded around the second glazing and fixed face F4. From the outlet of the inner glass a distance of 20 to 150 mm is preferably provided.
    In one embodiment, the electrical connection element (in particular the connector part) comprises: a flexible support preferably polymeric transparent or not (such as a PET etc.) with first front face and first rear face, son or preferably conductive tracks on the front or rear side, - possibly electronic components such as transistors - the wires or tracks (and electronic components) being covered by an electrically insulating material, such as a layer of resin or varnish (liquid deposit, etc.) or a protective film transparent or not (PET, polyimide, etc.), for example adhesive-coated,
    The connection part can be connected by any known means to the AMOLED screen: clipping, plugging. Preferably the connector part and the AMOLED screen are connected by one or permanent (solid) links. A connection between the connection part and the AMOLED screen can be done on a technical edge of the AMOLED screen.
    Preferably, as flexible polymeric film is chosen a polyethylene terephthalate PET, a polyimide, a polyester, a polyvinyl chloride PVC, a polycarbonate, polyetheretherketone (PEEK), an acrylate, this for at least one of the following elements : - the AMOLED screen (substrate, rear or front protection film: front film, etc.), - the electrical connection element, in particular the connector part (substrate, rear or front protection film).
    In one embodiment, the laminated glazing comprises a plurality of AMOLED screens, in particular at the periphery of the same longitudinal or lateral edge, each with a dedicated interface box or a common interface box. 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 the case of a particular windshield (in particular a road vehicle), this AMOLED screen can be arranged peripherally and preferably in the central zone of the upper longitudinal edge, in particular in an area where the width of the outer masking layer is is of width L1 greater than its width LO driver 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).
    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 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

    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.

    The internal masking layer can form not only: - a masking of the portion of connectivity, opaque or weakly transparent, - as well as a masking of the technical edges of the AMOLED screen, seen from the inside of the glazing, in particular the screen breeze, - and even, beyond the technical edge or edges, the junction between the lamination interlayer and the AMOLED screen, junction which may include irregularities and faults, (and even the junction between the lamination interlayer and the connectivity part). The masking element may be part of a support film and / or protection such as polyethylene terephthalate (PET) of the AMOLED screen and the connection part.
    The opaque film can be put in adhesion with the whole of the AMOLED screen and the connector part as soon as it is pre-assembled for storage, or else be part of a film that has been put in adhesion with this pre-assembled set. film, which can then optionally eliminate a pre-cut unwanted part before assembly of the windshield. The masking element (opaque film etc) can form not only: - a masking of the portion of connectivity, opaque or weakly transparent, - as well as a masking of the technical edges of the AMOLED screen, seen from the inside of the screen -brise, - and even, beyond the technical edge or edges, the junction between the lamination interlayer and the AMOLED screen, junction that may include irregularities and faults, (and even the junction between the interlayer of lamination and the connection part).
    The opaque film may also be an opacified extension of the transparent polymeric material covering the AMOLED screen, i.e., to be an integral part thereof.
    The opaque film may also alternatively or cumulatively be an extension of the polymeric material covering the part of the connector, that is to say of being an integral part.
    The inner masking layer or the masking element (the opaque film) may exceed the technical edges by at least 0.1 mm and even at most 5 mm or 2 mm. The two embodiments of the internal masking layer / masking element are not necessarily mutually exclusive, and one can imagine a masking of the technical edge of the AMOLED screen according to the first embodiment and a masking of the connecting element (the connector part) according to the second, or a double masking of the technical edge of the AMOLED screen or the connection element according to the two embodiments at a time.
    The masking function is to hide unnecessary and unsightly parts of the device to leave visible from the inside that the useful part; any method adapted to the nature of the substrate according to the first or second embodiment, may be employed: printing such as inkjet, screen printing, enamel as on the face F2 ....
    The internal masking layer may be confined to masking the technical edge (s) and part (at least the visible one) of the electrical connection element (of the connector part), or even possibly exceeding a little of at most 1 at 2cm. The internal masking layer may be in the zone with the AMOLED screen of a width less than or equal to that of the external masking so that the external masking is visible by transparency on either side of the AMOLED screen.
    An inner and / or outer masking layer may be a dark enamel layer (black), but more broadly a layer of paint or opaque ink, or a layer of painted polymer (eg printed PVB), for example polyethylene, polymethyl methacrylate (PMMA).
    The external masking layer on the face F2 and the internal layer on F3 or F4 are preferably made of the same material and even enamel. It is preferred to have an enamel layer at least face F2 and even face F4.
    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 schematic front view of a windshield with AMOLED screen of a motor vehicle, view on the inner side Figures 1a, 1a are schematic views of front and detail of a windshield with a screen AMOLED of a motor vehicle, inside view Figures 2, 3, 4, 5, 6, 7 are schematic views in section and partial of a windshield with AMOLED screen of a motor vehicle, inside 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 75 mm. 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)
    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. As a variant 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 interface box (at the periphery) is not represented.
    Figure 1 'is a partial schematic representation of the inside of a windshield 100' with AMOLED screen of a motor vehicle.
    The windshield 100 'differs from that in FIG. 1 in that the AMOLED screen is arranged vertically (H3 is larger and W3 is smaller). For example, H3 is 150 mm to 300 mm and W3 is 60 to 120 mm.
    The interface box (periphery) is not shown.
    As a variant not shown, two AMOLED screens are provided in this central zone on either side of the AMOLED screen: for example, also arranged in a vertical manner, for example arranged horizontally
    Figure 1a is a partial schematic representation of the inside of a windshield 100a with AMOLED screen of a motor vehicle.
    The windshield 100a differs from that in FIG. 1 in that the AMOLED screen is arranged in a transparent zone (required) for example with the high edge 34 'at the limit of the full area 51. The interface box ( periphery) is not shown.
    Figure 1a is a schematic front view and detail of a 100bis windshield with AMOLED screen of a motor vehicle, view on the inside.
    For simplicity the outer masking layer is not shown while it covers the area of the AMOLED screen (which is peripherally, opaque or weakly transparent). The elements in solid lines are seen through transparency through the inner glazing.
    As in FIG. 1, the AMOLED screen 3 is arranged horizontally in the central zone of the high longitudinal edge 15b. The windshield 100bis comprises an outer mineral glass sheet 1 and an inner mineral glass sheet 1 'whose upper edge 15b has a notch 11'. 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 more technical edges (here four) in narrow peripheral lateral fringes 33 and 33', low 34, high 34 'of width generally at least 0.5mm. 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 front side F3 and a front side surface 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, - extended out of the edge of the second glazing by a so-called external portion 45 flexible, curved and fixed by bonding F4 face without extending to the display area 32 'via a so-called end portion 47 terminated by its connector 8 in an accessible area at the time of assembly / disassembly. 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.
    The interface housing 70, for example parallelepipedal, is connected to the connector 8 here on a lateral edge and on another edge (here longitudinal) to a connector 71 of a power supply cable 72. d is for example a few cm.
    Figure 1'bis.is a schematic front view and detail of a windshield 100'bis AMOLED screen of a motor vehicle, seen on the inside. For simplicity the outer masking layer is not shown while it covers the area of the AMOLED screen (periphery, opaque or weakly transparent). The elements in solid lines are seen through transparency through the inner glazing.
    It differs from the windshield 100bis by its arrangement in the vertical.
    The interface box 70, for example parallelepiped, is mounted on the end portion 47 and connected on an edge (here lateral) to a connector 71 of a power supply cable 72. d is for example a few cm.
    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 an end portion 47 terminated by its connector 8 in an area accessible at the time of 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 advantageously t be of the 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 V 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 interface box 70 adhesively bonded 7a (pressure sensitive, etc.) on the face F4 14 is for example parallelepipedal is connected to the connector 8 here on a longitudinal edge and on another edge (here lateral) to a connector 71 a power supply cable (not shown), d is for example a few cm. 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 0.15mm or even 0.2mm, it is possible to delete the central sheet 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.
    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 interface housing 70, for example parallelepipedal, is adhesively mounted 7a (adhesive, pressure sensitive, etc.) on the end portion 47 and connected on an edge (here lateral) to a connector 71 of a power supply cable ( not shown), d is for example a few cm.
    The width of the adhesive 7 can be increased.
    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 6T, 62 'of the technical edges 34 of the AMOLED screen 3, seen from the inside 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.
    Figure 5 is a schematic sectional and partial view of a windshield 500 with AMOLED screen of a motor vehicle, inside view.
    It differs from the previous windshield 400 in that for aesthetic reasons the electroconductive layer is absent at least in the area 91 facing the display area 32 '.
    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.
    Figure 7 is a schematic sectional and partial view of a windshield 700 with AMOLED screen of a motor vehicle, view on the inside.
    It differs from the windshield 600 by replacing the inner masking layer 6 with an opaque film 6 '(as in FIG. 5) on the AMOLED screen and the FPC 40 on the front side. One can also a 6 "opaque film (as in Figure 5) on the AMOLED screen and the FPC 40 rear side in addition to or in replacement of the enamel of the edge 51.
