    DESCRIPTION
    The present invention relates to the field of interfacing devices (human-machine interface) integrating display means and control means, in particular tactile and mechanical means. The invention is preferably aimed at devices of the aforementioned type intended to be integrated in a dashboard, in particular of a motor vehicle.
    The present invention relates to an interfacing device comprising a touch screen and a control button or the like.
    Numerous embodiments of devices of the aforementioned type are already known, in particular composite devices comprising control means both mechanical and electronic. This is the case of the solution proposed by US Pat. No. 8,330,713 or EP2,511,807.
    Many of these solutions implement a combined means of display and control in the form of a touch screen generally referred to as "touch screen". These screens comprise, in a known manner and as shown in FIG. 1, a bidirectional matrix consisting of either band-shaped electrodes or connecting lines, arranged in rows (rows) Y and in columns X. These two series ( X, Y) of band electrodes or of connecting lines define or are connected to active pixels capable of detecting the contact of a finger of a user for example. The aforementioned first technology comprises crossed conductive strips, forming a two-dimensional grid with constitution of electrodes at superimposed crossing points. The aforementioned second technology based on crossed control lines connected to point transistors arranged in two-dimensional matrix is known to those skilled in the art under the designation of active matrix screen TCM (Thin Film Transistors) or TET. The various aforementioned means (crossed strips forming electrodes, control lines connected to point transistors) are generally integrated between two glass plates forming a touch screen and covering the visible face of a liquid crystal display screen (AMLCD / TFT- LCD) or organic electroluminescent diodes (AMOLED).
    The touch screen technologies mentioned above are known to those skilled in the art under the designation of projected capacitive technology or surface capacity, including as subcategories that of "mutual capacity" and that called "self-capacity". ".
    The bands or lines of each of the two series X, Y of electrodes or lines are connected by a respective collective connection means to at least one contact detection controller, making it possible to locate the place of contact.
    In these known embodiments, the mechanical control element, for example a movable, translational, rotatable or segmented button, is maintained on the visible front face of the touch screen panel or keypad by magnetic attraction and its position and / or its displacement are identified (s) by sensors located on the rear opposite side of said panel, as well as the electromagnet retaining the button provided with at least one ferromagnetic insert detectable by the aforementioned sensors.
    It has also been proposed to use the transparency properties of the screen to transmit light signals through it, signals that can be identified by a suitable optical sensor located on the rear face.
    Although these known solutions give at least partly satisfaction, there is a demand for, on the one hand, a simpler and more robust fixing of the mechanical means on the screen, and, on the other hand, a possibility of physical communication. between the two sides of the screen, in particular at the level of the zone receiving the mechanical means, without disturbing the performance or the operating modes of the touch screen, in particular related to the two-dimensional arrangement of bands or lines. For this purpose, the subject of the invention is an interface device with a touch screen comprising a two-dimensional matrix of elementary capacitive detectors formed by an array of electrodes in the form of crossed strips or by electrodes connected to control lines or connecting, all these bands or rows being arranged in rows and columns and connected to a respective controller, this device also comprising at least one button or a similar mechanical movable control mechanical member, manually operated and arranged on the apparent functional face of the touch screen, characterized in that at the level of the localization area of the button or the similar member, the touch screen has at least one aperture or through cutout, in that the button or the similar body presents at least one means or a display or light-signaling zone operatively connected to a power supply means power, in light or in images through said at least one opening or cutout and in that the constituent portions separated from the strips or lines interrupted by the cutout (s) or aperture (s) are all electrically connected to a controller. The invention will be better understood, thanks to the following description, which refers to the preferred embodiments, given as non-limiting examples, and explained with reference to the appended diagrammatic drawings, in which: FIG. schematic representation of a touch screen incorporating a two-dimensional matrix of strip electrodes, illustrating the negative impact of the realization of a through opening at the level of the two-dimensional detection matrix (see the two rectangles in dotted lines identifying the portions of unrelated bands); Figure 2 is a schematic representation of a touch screen as shown in Figure 1 comprising an improvement according to a first embodiment of the invention, to overcome the aforementioned negative impact; FIG. 3 is a partial schematic representation of a touch screen of the state of the art on which only the horizontally extending and superimposed electrode strips in the vertical direction of the screen (Y series) are shown; FIG. 4 is a representation similar to that of FIG. 3, illustrating the embodiment of the continuity of the Y electrode strips in the presence of an opening, in accordance with a second embodiment of the invention; FIG. 5 is a representation similar to that of FIG. 3, illustrating the embodiment of an electrical connection of all the electrodes and electrode portions in the presence of a through opening, in accordance with a third embodiment of FIG. the invention, and, Figures 6A and 6B are partial views in section, in a plane perpendicular or plane of the screen and containing the axis of rotation of the button, two embodiments of an interface device according to the invention.
