First Claim
Patent Images
1. A vehicle display device, which device comprises:
- an optically transparent laminated windshield having inner and outer juxtaposed plies, an interlayer disposed between said plies, said interlayer being optically transparent and adhering to said plies so as to join them in a laminated construction, a TOLED which is located so as to be in the field of vision of an operator of the vehicle and which is likewise disposed between said plies, and transparent conductor means leading to said TOLED for activating said TOLED to generate light within said plies of the windshield to provide a head-up message or the like in the field of vision of such operator so the operator'"'"'s eyes may always remain on the road ahead.

Abstract
A head-up display (HUD) is incorporated within a windshield of a motor vehicle at a location through which the operator'"'"'s field of vision onto the highway ahead must pass. The TOLED is formed of transparent materials and laminated, along with a polymeric interlayer, between two plies of glass; a pair of elongated conductors electrically connect the electrodes of the TOLED to an edge of the windshield. Upon the receipt of signals from a controller, light is created within the plies of the windshield to immediately convey a HUD to the operator without the need for his or her vision to leave the highway ahead.

12. A motor vehicle windshield which comprises:
-
inner and outer plies of glass shaped to close a window opening in the front of an a motor vehicle, a polymeric interlayer of transparent material securing said plies to each other, a thin transparent display device located in juxtaposition with said interlayer in a generally central location between an upper edge and a lower edge of said windshield, which display device contains a plurality of pixels that emit light when activated, transparent conductor means extending from said transparent display device to an edge of the windshield, and means for connecting said conductor means to an electronic unit for sending signals to said display device to emit light and thereby create a head-up display at a location generally centrally of the motor vehicle operator'"'"'s field of vision through the windshield toward the road ahead.

13. A method for presenting a head-up display to the operator of a motor vehicle in a manner so the operator'"'"'s eyes never need to leave the road ahead, which method comprises:
-
providing a thin transparent display device at a location between inner and outer plies of glass shaped to constitute a motor vehicle windshield at a generally central location between an upper edge and a lower edge of said windshield, which display device contains a plurality of pixels that emit light when activated, connecting the display device via transparent conductor means extending from said transparent display device to an edge of the windshield, connecting said conductor means to an electronic unit, and sending signals from said electronic to said display device to cause said display device to emit light and thereby create a head-up display at a location generally centrally of the motor vehicle operator'"'"'s field of vision through the windshield toward the road ahead.
