Description

[0234] The present invention will be better understood and other details and advantageous characteristics of the invention will be apparent on reading the examples of laminated vehicle glazings according to the invention and illustrated by the following figures:

[0235] FIGS. 1, 1, 1a, and 8 are each a face-on schematic view of a windshield with AMOLED screen of an automotive vehicle, inside view

[0236] FIGS. 1bis, 1bis, 2a, 2b are face-on and detail schematic views of a windshield with AMOLED screen of an automotive vehicle, inside view

[0237] FIGS. 2, 3, 4, 5, 6, 7 are sectional and partial schematic views of a windshield with AMOLED screen of an automotive vehicle, inside view.

[0238] It is specified that out of concern for clarity the various elements of the objects represented are not necessarily reproduced to scale. For simplicity, the glazings are not represented cambered nor are the flexible elements in the lamination represented curved while adapting to this or these curvatures (in two dimensions) of glazing.

[0239] FIG. 1 is a partial schematic representation viewed from the interior of a windshield with AMOLED screen 100 of an automotive vehicle.

[0240] The windshield 100 comprises a clear view central zone (central part of the interior glazing 1 therefore face F4 side 14) and an external masking peripheral frame 5, bottom 15a and top 15b, left lateral 15c and right lateral 15d longitudinal edges, frame here masking the rear of the opaque or slightly transparent AMOLED screen 3 (not transparent enough to be in the clear window region). The external masking layer 5, on face F2, thus hides from a view of the exterior of the vehicle the AMOLED screen 3 (and its connector not represented here, preferably in the laminate). The function of the enamel 5 is first to hide, viewed from the face F1, the glue bead fastening the final laminated glazing to the bodywork bay.

[0241] The AMOLED screen is arranged in a central position of the top longitudinal edge 15b in a horizontal manner and is rectangular. It is (all or part) in a so-called widened zone the width (vertical dimension) L1 of whose enamel is larger than the adjacent width L0 (for example on the left) serving for the conventional and even copilot side masking.

[0242] For example, the horizontal dimension or width W3 is at least 120 mm and even up to 250 mm. The vertical dimension or height H3 is at least 75 mm.

[0243] Here the AMOLED screen 3 is down at the bottom-most of the widened peripheral zone. Its bottom edge 34 is in proximity to or on the boundary of the enamel flat patch 51 (solid zone) rather than on the boundary of the optional zone with enamel patterns for example at most 15 mm in width. Its top edge 34 can be as high as possible (to the limit of the zone of vision in the cabin), typically at least 15 mm and better at least 70 mm. This depends on the design of the windshield (size, inclination, clear view desired by the maker).

[0244] The edges 53, 53 of the widened enamel zone 50 can protrude beyond the lateral edges 33 and 33 for example by at most 2 cm or even 1 or 0.5 cm (limit of the solid zone). In the off state, the AMOLED screen is dark and is even barely if at all distinguishable from the enamel background 5 (protruding over the sides). It is possible to adapt the enamel color accordingly. Preferably the enamel is opaque and dark.

[0245] The AMOLED screen is here in a distinct peripheral zone from the transparent central zone termed zone A Z.sub.A (the most central and in two parts, quadrilateral-like) or of the restricted zone B Z.sub.b (dashed).

[0246] A first sensor forming a rain sensor (not visible here) is behind the AMOLED screen within the lamination in the zone swept by a windshield wiper.

[0247] On the lit AMOLED screen 3, it is possible to see the central vision of the rear of the vehicle and preferably the lateral visions of the vehicle.

[0248] The AMOLED screen can have the rear vision function. It can also have other functions such as: telephone mode, television mode, display of environmental data or data on the road (maps, GPS etc) or on the vehicle, simultaneous display on one or more screen zones (for example in the manner of a mobile telephone screen).

[0249] In a variant, not shown, the AMOLED screen is on the drivers side top longitudinal edge. It is higher but can be wider than in the central zone and protrude into the central zone (away from projecting enamel zone).

[0250] As a variant, not shown, the AMOLED screen is on the drivers side bottom longitudinal edge in the vision zone. It can be wider than in the central zone.

[0251] As a variant, not shown, the AMOLED screen is on the drivers side bottom lateral edge and is arranged vertically as low down as possible in the vision zone.

[0252] FIG. 1 is a partial schematic representation viewed from the interior of a windshield 100 with AMOLED screen of an automotive vehicle.

[0253] The windshield 100 differs from that in FIG. 1 in that the AMOLED screen is arranged in a vertical manner (H3 larger and W3 smaller). For example H3 is 150 mm to 300 mm and W3 is 60 m to 120 mm.

[0254] As a variant, not shown, two AMOLED screens are disposed in this central zone on either side of the AMOLED screen: [0255] for example also arranged in a vertical manner [0256] for example arranged in a horizontal manner

[0257] FIG. 1a is a partial schematic representation viewed from the interior of a windshield 100a with AMOLED screen of an automotive vehicle.

[0258] The windshield 100a differs from that in FIG. 1 in that the AMOLED screen is arranged in a required transparent zone for example with the top edge 34 at the limit of the solid zone 51. The first sensor is behind or in the adjacent (widened) central zone.

[0259] FIG. 1bis is a face-on and detail schematic view of a windshield 100bis with AMOLED screen of an automotive vehicle, inside view showing different possible positions of sensors.

[0260] For simplicity the external masking layer is not represented although it covers the zone of the AMOLED screen (which is peripheral, opaque or slightly transparent). The solid-line elements are seen by transparency through the interior glazing 1.

[0261] As in FIG. 1, the AMOLED screen 3 is arranged horizontally in the central zone of the top longitudinal edge 15b. The windshield 100bis comprises an exterior mineral glass sheet 1 and an interior mineral glass sheet 1 whose upper edge 15b exhibits a notch 11.

[0262] The AMOLED screen 3 is sandwiched between the exterior glass sheet 1 and the interior glass sheet 1. It exhibits a display zone 32 flanked by one or more technical edges (here four) in narrow lateral peripheral 33 and 33, bottom 34, top 34 bands generally at least 0.5 mm in width. It is supplied through an electrical connection element 4 of the AMOLED screen 3 which comprises: [0263] a flexible so-called connecting part 40 between the face F2 and the face F3 within the lamination interlayer with a front surface on the face F3 side and a rear surface on the face F2 side, of thickness E4 less than that E2 of the lamination interlayer, linked to the AMOLED screen and extending the AMOLED screen in the direction of the lip of the second glazing, [0264] extended outside of the lip of the second glazing by a flexible so-called exterior part 45, curved and fixed by gluing on face F4 without stretching as far as the display zone 32 via a part 47 terminated by its connector 8 in a zone accessible at the time of mounting/dismantling.

[0265] The connection element 4 is a flexible printed circuit (FPC) suitable for the implementation of 2560?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 polyvinylbutyral (PVB set back a little with respect to the glazing edges). The interior glass 1 comprises a notch 11. The dimensions of the notch 11 are suited to the FPC 4: [0266] width of the notch 11 greater than or equal to that of the FPC 4; [0267] depth of the notch 11 greater than or equal to the thickness of the FPC 4 preferably so as to prevent the FPC 4 being visible from the exterior in a case when the edge is evident.

[0268] In practice the depth of the notch 11 lies between 1.5 mm and 2 mm. The zone of the notch 11 is substantially devoid of lamination interlayer.

[0269] Between the face F2 and the rear face of the AMOLED screen 3, it is possible to place sensors notably with conducting layer or electroconducting wires in particular a rain detector 72 for example of capacitive type in the zone of the windshield wiper or else two cameras (stereoscopic vision) 71, 71 for the visible or the infrared on the face F2, more precisely each glued in an opening (detection area) of an enamel on face F2.

[0270] Alternatively or cumulatively, it is possible to place one or more sensors 70 between the face F2 and the rear surface 41 of the FPC, notably on or integrated into the FPC 40 before mounting (and even before shrouding). A predetermined zone is provided on the FPC for this purpose for example by widening the FPC.

[0271] Alternatively or cumulatively, it is possible to place one or more sensors 70a alongside the FPC 40, in one and the same plane and of the same thickness preferably and even to use the notch 11 to afford an exit for a flexible supple support carrying the sensor or sensors 70a.

[0272] Alternatively or cumulatively, it is possible to place one or more sensors 73, 75 in proximity to and at the periphery of the AMOLED screen 3 (here left side and below), on the face F2 or on the face F3 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 window region or else in front of the background of the external masking layer with optional opening forming a detection area). This can be cameras or photodiodes.

[0273] FIG. 1bis is a face-on and detail schematic view of a windshield 100bis with AMOLED screen of an automotive vehicle, inside view. For simplicity the external masking layer is not represented although it covers the zone of the AMOLED screen (peripherally, opaque or slightly transparent). The solid-line elements are seen by transparency through the interior glazing 1.

[0274] It differs from the windshield 100bis by its arrangement vertically.

[0275] Between the face F2 and the rear face of the AMOLED screen, it is possible to place sensors notably with conducting layer or electroconducting wires in particular a rain detector 72 in the zone of the windshield wiper, for example of capacitive type.

[0276] Alternatively or cumulatively, it is possible to place one or more sensors 70 between the face F3 and the front surface of the FPC, notably on or integrated into the FPC before mounting (and even before shrouding). A predetermined zone is provided on the FPC for this purpose for example by widening the FPC. This sensor can thereafter be masked by an enamel on face F3 or F4 or an opaque overlayer on the FPC 40.

[0277] Alternatively or cumulatively, it is possible to place one or more sensors 70a alongside the FPC, in one and the same plane and of the same thickness preferably and even to use the notch 11 for a flexible supple support carrying sensors 70a. This sensor can thereafter be masked by an enamel on face F3 or F4 or an opaque overlayer on the FPC 40.

[0278] Alternatively or cumulatively, it is possible to place one or more sensors 75a, 75b in proximity to and at 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 external masking layer (or not, if they are invisible). This can be two cameras (stereoscopic vision) for the visible or the infrared on the face F2 or F3, more precisely each glued in an opening (detection area) of an enamel on face F2.

[0279] FIG. 2 is a sectional and partial schematic view of a windshield 200 with AMOLED screen of an automotive vehicle, inside view.

[0280] The windshield 200 comprises: [0281] a first glazing 1, with a first main face 11 termed F1, intended to be on the outside of the vehicle, and a second opposite main face 12 termed F2, preferably of thickness E1 of at most 2.5 mm, in particular a preferably tinted soda-lime-silica float glass sheet, with a 2.1 mm thickness of glass such as a TSA glass from the Applicant company [0282] a lamination interlayer of polymeric substance 2, on the face F2 side, of thickness E2 preferably of at least 0.76 mm such as polyvinylbutyral (PVB) [0283] a second glazing 1, with a third main face 13 termed F3 on the lamination interlayer 2 side and a fourth opposite main face 14 termed F4, intended to be on the inside of the vehicle, preferably of thickness E1 of at most 2.2 mm, in particular a soda-lime-silica float glass sheet with a 1.6 mm thickness of glass, for example tinted such as a TSA glass from the Applicant company, [0284] between the face F2 and the face F3 and within the lamination interlayer, an organic light-emitting diode-based viewing screen, comprising a set of pixels, termed a flexible AMOLED screen 3, the AMOLED screen comprising a zone of dynamic information display 32, of thickness E3 less than E2 and preferably subcentimetric, AMOLED screen having a front main face 32 oriented toward the face F3 and a rear face 31 oriented toward the face F2, the AMOLED screen is arranged peripherally, [0285] within the lamination interlayer an electrical connection element 4 of the AMOLED screen.

[0286] The AMOLED screen 3 is therefore sandwiched between the exterior glass sheet 1 and the interior glass sheet 1. It exhibits a display zone 32 flanked by one or more technical edges (one, two, three or four) in narrow peripheral bands 34, 34 generally at least 0.5 mm in width (and less than 1 cm preferably). The AMOLED screen 3, flexible and extended directly toward an edge of the glazing, by the connection element 4 which is linked to it and extends outside the lamination.

[0287] It is supplied through an electrical connection element 4 of the AMOLED screen 3 which comprises: [0288] a flexible so-called connecting part 40 between the face F2 and the face F3 within the lamination interlayer with a front surface 42 on the face F3 side and a rear surface 41 on the face F2 side, of thickness E4 less than that E2 of the lamination interlayer linked to the AMOLED screen and extending the AMOLED screen in the direction of the lip of the second glazing 1, [0289] extended outside of the lip of the second glazing via a so-called exterior part 45 and curved and fixed by gluing (on face F4 without stretching as far as the display zone 32 via a part 47 terminated by its connector 8 in a zone accessible at the time of mounting/dismantling.

[0290] The connection element 4 is a flexible printed circuit (FPC) suitable for the implementation of 2560?1600 pixels (AMOLED screen). The FPC 4 could 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 (set back a little with respect to the glazing edges).

[0291] The interior glass 1 comprises a notch 11. The dimensions of the notch 11 are suited to the FPC 4: [0292] width of the notch 11 greater than or equal to that of the FPC 4; [0293] depth of the notch 11 greater than or equal to the thickness of the FPC 4 preferably so as to prevent the FPC 4 being visible from the exterior in a case when the edge is evident.

[0294] In practice the depth of the notch 11 lies between 1.5 mm and 2 mm. The zone of the notch 11 is substantially devoid of lamination interlayer.

[0295] The AMOLED screen 3 has for example a thickness E3. The connecting part 40 can be less thick. It is optionally covered or shrouded with any material so as to increase (if necessary) the thickness E4 thereof to a value substantially equal to E3. If E4 is equal of 0.4 mm, E3 is from 0.38 to 0.40 mm. A central ply 22 of 0.38 mm is for example used for the lamination, with a reserve to house the AMOLED screen and the connecting part and two external plies 22, 23 of 0.17 mm or 0.38 mm. One of the external plies can be thicker for example 0.76 mm.

[0296] It is possible to have more than 3 plies (if insertion of a polymeric film such as a PET etc) or for more mechanical protection.

[0297] When the AMOLED screen is at most 0.15 mm or even at most 0.2 mm in thickness, it is optionally possible to eliminate the central ply during assembly.

[0298] The first glazing (exterior) 1 comprises an external masking layer 5 on face F2, opaque, of black enamel preferably, [0299] with an edge 51 toward the center of the windshield [0300] and an edge 52 on the lip side of the glazing 15 for example at a distance of at most 3 or 1 mm from the lip 15.

[0301] It hides not only the glue bead 7 of the trim 7 but also the AMOLED screen 3 (opaque or slightly transparent), the connecting part 40 and the off-glazing part 45 of the FPC and the part 47 and its connector 8.

[0302] The external masking layer 5 is preferably a solid zone (a flat patch) rather than a network of patterns. Beyond the edge 51 it can be extended by a network of patterns (made of the same substance) for example in gradation over a width of at most 15 mm and even 5 mm and even larger if the lip 15 is the lower longitudinal edge.

[0303] The second glazing 1 (interior) comprises on face F4 an internal masking layer 6 on face F4 (or as a variant F3), opaque, of black enamel preferably, with [0304] an edge 61 toward the center of the windshield [0305] an edge 65 on the notch side.

[0306] This internal masking layer 6 masks from the interior the entire surface of the connecting part 40 in particular that which is in the vision zone (away from zone with trim or optional casing). It can be wider than the connecting part.

[0307] This internal masking layer also masks from the interior the technical edges 34, 34 of the AMOLED screen. It can protrude for example by at most 10 mm opposite the lamination interlayer over the perimeter of the technical edges in order to mask lamination defects.

[0308] When the internal masking layer 6 is thus on the perimeter of the AMOLED screen 3, an opening 63 has therefore been formed (masking or post fabrication of the layer) revealing the display zone 32.

[0309] It can also protrude further beyond the technical edges so that its width is (almost equal) to that of the external masking layer 5 on either side of the AMOLED screen (and/or of the connecting part).

[0310] The internal masking layer 6 is preferably a solid zone (a flat patch) rather than a network of patterns. Beyond the edge 61 it can be extended by a network of patterns (made of the same substance) for example in gradation over a width of at most 15 mm and even 5 mm and even larger if the lip of the notch 11 is the lower longitudinal edge. The sensors can be placed preferably in the windshield wiper sweep zone and/or: [0311] on the face F2, behind the AMOLED screen, for example sensor 71 which is capacitive and for example a rain detector and sensor 72 which is a camera opposite a local opening 53 of the masking layer 72 [0312] and/or on the face F2, behind the connecting part 40, for example sensor 70 which is which is capacitive and [0313] and/or on the face F2 in a transparent zone (of clear window region), sensor 73 for example a camera, or an optionally transparent sensor if necessary, [0314] and/or on the face F3 in a transparent zone (of clear window region), sensor 74 for example a camera, or an optionally transparent sensor if necessary notably with transparent electroconducting layer or sufficiently fine wire(s).

[0315] The sensor 71 or 70 can comprise an electroconducting layer such as a conducting enamel on the enamel on F2.

[0316] Power supply conductors for the sensors can exit through the notch 11 or in proximity. A sensor 76 is on the face F4 in the field of vision, on the enamel 6 on F4, preferably it is in a housing. It serves for example as antenna element for signals used by the AMOLED screen. This can be a conducting enamel on the enamel 6. This can be a transparent or opaque layer under the enamel 6 (no masking housing necessary).

[0317] Other sensors for the AMOLED screen can be at the front of the vehicle or in the dashboard.

[0318] The sensors notably with layer or with electroconducting wires can be covered with a polymeric film (adhesive-coated) such as a polyimide, a PET or else with a varnish so as to be insulated from the PVB.

[0319] A sensor can influence one or more display parameters of the AMOLED screen: luminance, contrast etc as a function of the day or of the night or as a function of the climate (snow, rain, fog). A sensor can serve for a GPS function of the AMOLED screen. The rain detector can be coupled to the AMOLED screen notably to indicate a reduced speed limit (in addition to actuating the windshield wiper or wipers).

[0320] A sensor can evaluate the distance to an obstacle or car in front and notably alert the driver regarding too short a safety distance via the AMOLED screen. The camera or cameras in the visible (73 or 74 preferably) also serve to detect fog notably so as to indicate a reduced speed limit via the AMOLED screen.

[0321] The camera or cameras in the infrared (73 or 74 preferably) serve at night to alert via the AMOLED screen for example of the presence of animals or of bikes etc

[0322] A photodiode serves for example to evaluate the natural illumination so as to adjust the luminance of the AMOLED screen.

[0323] A temperature sensor can serve to regulate the operating parameters of the AMOLED screen.

[0325] 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 a central or non-central position. [0326] lateral edges 64 and 64 protruding preferably by at least 3 mm and [0327] bottom edge 61 protruding preferably by at least 3 mm.

[0328] As in FIG. 2, there are: [0329] sensors 70, 71, 71, 72 (dashed) behind the display zone 32 of the AMOLED screen or the connecting part 40 of the FPC 4 here of width equal to the AMOLED screen [0330] a sensor 74 on face F3 (or F3) in a transparent zone beyond the edge 61 (and beyond the enamel on face F2).

[0331] 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): [0332] sensor 73 bottom edge side 61, on the face F3 or F2 [0333] sensor 75 lateral edge side (here left) 64, on the face F3 or F2.

[0334] Provision may even be made for one or more sensors on the technical edges of the AMOLED screen, optionally sufficiently wide for this purpose.

[0335] The internal masking layer 6 is alternatively a strip of given width with an opening for the AMOLED screen, [0336] strip along the upper or lower longitudinal edge, the AMOLED screen arranged horizontally being on the drivers and/or copilot's side [0337] strip along the left or right lateral edge, the AMOLED screen arranged vertically on the drivers and/or copilot's side.

[0338] FIG. 2b is a face-on and detail schematic view of a windshield 200b with AMOLED screen of an automotive vehicle, inside view.

[0339] It differs from the windshield 200a by its arrangement vertically.

[0340] As in FIG. 2, there are: [0341] sensors 72; 70 behind the display zone 32 of the AMOLED screen or the connecting part 40 of the FPC 4 here of width equal to the AMOLED screen [0342] a sensor 74 on face F3 (or F3) in a transparent zone beyond the edge 61 (and beyond the enamel on face F2).

[0343] 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): [0344] sensor 73 bottom edge side 61, on the face F3 or F2.

[0345] Provision may even be made for one or more sensors on the technical edges of the AMOLED screen, optionally sufficiently wide for this purpose.

[0346] FIG. 3 is a sectional and partial schematic view of a windshield 300 with AMOLED screen of an automotive vehicle, inside view.

[0347] The windshield 300 differs from the windshield 200 firstly in that the internal masking layer is on face F3 instead of face F4.

[0348] The windshield 300 differs from the windshield 200 also in that the masked sensors 71, 72, 70 on face F2 are henceforth on the rear face 31 or the rear surface 41, for example on a polymeric film such as a PET. The sensor or sensors can comprise in particular an electroconducting layer deposited on the polymeric film with optionally an inserted barrier layer. They can also be covered with a polymeric film (adhesive-coated) such as a polyimide, a PET or else with a varnish so as to be insulated from the PVB.

[0349] The sensor 76 can be invisible or quasi-invisible for example comprises a layer of ITO or other conducting transparent oxide.

[0350] FIG. 4 is a sectional and partial schematic view of a windshield 400 with AMOLED screen of an automotive vehicle, inside view.

[0351] It differs from the windshield 200 in that the internal masking layer 6 is replaced with an opaque (opacified) film 6 of polyethylene terephthalate (PET) that can be stuck to the whole of the AMOLED screen 3 and of the FPC 4 immediately when premounted with a view to its storage, or else form part of a film which has been stuck to this premounted assembly, from which film can then optionally be removed an undesired part precut before assembling the windshield.

[0352] The opaque film 6 constitutes: [0353] a masking of the FPC 40, opaque or slightly transparent, and of the junction between the PVB 22 (central part) and the AMOLED screen 3, which can comprise irregularities and flaws, [0354] as well as a masking 61, 62 of the technical edges 34 of the AMOLED screen 3, seen from the interior side of the windshield.

[0355] The opaque film 6 can also be an opacified extension of the transparent polymer material covering the AMOLED screen, that is to say be an integral part thereof.

[0356] The opaque film 6 can also alternatively or cumulatively be an extension of the polymer material covering the FPC, that is to say be an integral part thereof.

[0357] Moreover, the face F3 is furnished with an electroconducting layer 9 and optionally with a current infeed 9 for the latter; this layer can consist of a stack which reflects solar radiation, in silver or other, or with a heating coating/stack furnished for this purpose with its current infeed 9. It can be covered directly with a masking of the technical edge of the AMOLED screen mentioned previously.

[0358] The sensors 71, 72, 70 masked on face F2 are henceforth on a transparent or non-transparent polymeric film 77 such as a PET laminated in the PVB between face F2 and rear surface 31 and rear face 41 and preferably exiting notch side (and even folded back so as to be fixed on face F4. Alternatively this sensor-carrying film (PET) is in the same plane as the AMOLED screen, in proximity and even exits through the notch 11. The sensor 74 on the face F2 in the vision zone is a zone of the electroconducting layer 9. For example it forms an antenna element for the exterior (remote-toll-payment etc). Other zones of the electroconducting layer 9 can form a sensor [0359] zone 76a opposite the display zone for example antenna element for the interior [0360] zone 76 opposite the masked front surface 42 example antenna element for the interior or mist detector.

[0361] 76a and 76 are transparent sensors.

[0362] FIG. 5 is a sectional and partial schematic view of a windshield 500 with AMOLED screen of an automotive vehicle, inside view.

[0363] It differs from the previous windshield 400 in that for esthetic reasons the electroconducting layer is absent at least in the zone 91 opposite the display zone 32. For esthetic reasons the electroconducting layer is absent at least in the zone 91 opposite the display zone 9. This opening 91 can be larger (toward the left of the drawing) so as to remove the coloration due to the reflection of the layer. It can also increase the LT in a zone of clear window region (without enamel).

[0364] FIG. 6 is a sectional and partial schematic view of a windshield 600 with AMOLED screen of an automotive vehicle, inside view.

[0365] It differs from the windshield 200 in that the AMOLED screen 3 is placed in a transparent vision zone of which without external masking layer 6 behind.

[0366] However the masking of the exterior of the technical edges 34, 34 (and even of the PVB 22) by the external enamel layer 5,51 can be accepted. Hence the enamel layer 5 can have an opening 53 facing the AMOLED screen zone. And the masking of the interior of the technical edges 34, 34 (and even of the PVB 22) by the internal enamel layer 6,61 can be accepted. Hence the enamel layer 6 can have an opening 63 facing the AMOLED screen zone.

[0367] The sensors on the face F2 opposite the AMOLED screen zone have been eliminated or are sufficiently transparent. It is possible to add one or more sensors 70, 72 behind the FPC 4 again masked (fairly transparent with difficulty).

[0368] Provision may be made for sensors 71, 70 integrated into the AMOLED screen or the FPC 40.

[0369] FIG. 7 is a sectional and partial schematic view of a windshield 700 with AMOLED screen of an automotive vehicle, inside view.

[0370] It differs from the windshield 600 by the replacement of the internal masking layer 6 by an opaque film 6 (as in FIG. 5) on the AMOLED screen and the FPC 40 on the front side.

[0371] It is also possible an opaque film 6 (as in FIG. 5) on the AMOLED screen and the FPC 40 on the rear side in addition to or as replacement for the enamel of the edge 51.

[0372] FIG. 8 is a face-on view of a road vehicle windshield which illustrates the possible peripheral zones for an opaque or slightly transparent or even very transparent AMOLED screen 3 (without rear masking) and shows the central transparent zone for a very transparent AMOLED screen 3.

[0373] This figure shows distances defining the limits of the vision zone of the driver (or copilot) and of the zone A Z.sub.A or of the restricted zone B Z.sub.B.

[0374] The following pairs of distances are defined: [0375] h1 distance between the upper edge of the windshield and the upper limit F of the peripheral zone of vision of the driver or of the copilot in the vehicle, preferably of at least 15 mm and h2 distance between the upper edge and the upper limit F of the central zone of transparency on the driver's or copilot's side, of at least 120 mm, the AMOLED screen 3 is between said limits F and F as well as preferably the optional other AMOLED screen(s) in this zone [0376] h1 distance between the lower edge of the windshield and the lower limit F1 of the peripheral zone of vision of the driver or of the copilot in the vehicle preferably of at least 40 mm and h2 distance between the lower edge and the lower limit F1 of the central transparency zone on the driver's or copilot's side of at least 120 mm, the AMOLED screen 3a is between said limits F1 and F1 as well as preferably the optional other AMOLED screen(s) in this zone [0377] h4 distance between the lateral edge of the windshield and the lateral limit F2 of the peripheral zone of vision of the driver in the vehicle preferably of at least 15 mm and h5 distance between the lateral edge and the lateral limit F2 of the central zone of transparency on the drivers side or the copilot's side of at least 80 mm, the AMOLED screen 3b is between said limits F2 and F2 as well as preferably the optional other AMOLED screen(s) in this zone [0378] h1 distance between the upper edge of the windshield and the upper limit F3 of the peripheral zone of vision of the driver or of the copilot in the vehicle, preferably of at least 15 mm and H.sub.a distance between the upper edge and the upper limit F3 of the central transparency zone in the central part, of at least 180 mm, the AMOLED screen is between said limits F3 and F3 as well as preferably the optional other AMOLED screen(s) in this zone.

[0379] The enamel limits L1, L1, L1a, L1b can be respectively substantially equal to h2, Ha, h2, h5 when the AMOLED screen has to be masked.

[0380] As a variant the AMOLED screen is not masked from the rear (enamel strip less wide) in particular if very transparent.

[0381] Preferably the width of the top central zone wa is at most 300 mm.

[0382] The (automotive) road vehicle windshield of rectangular shape is: [0383] from 1350 to 1550 mm in width (horizontal dimension) Lp, [0384] from 950 to 1050 mm in height (vertical dimension) Hp.

[0385] By way of example we have h1=70 mm; h2=195 mm; h3=125 mm, Ha=270 mm; wa=300 mm; h6=75 mm; h4=25 mm; h5=125 mm; h=85 mm, hb=100 mm.
