Abstract:
An image display generator operable for use in generating an image, comprising:a sheet of transparent substrate material having a plurality of lenses formed in a first image projecting surface of that sheet; a layer of semiconductor material disposed on a second surface of the sheet; a plurality of selectively operable light generating devices formed in said semiconductor material layer, each said light generating device being aligned with a respective one of said lenses for directing light operatively emitted by said each light operating device in a first direction through said substrate toward the respective lens and in a second direction away from said substrate; a layer of transparent insulating material disposed over said semiconductor material; and a layer of reflective material disposed over said insulating material for receiving, from each light generating device and reflecting the second direction light back to the respective aligned lens so that each said respective lens collimates the first and second direction light produced by the respective each light generating device for projection from the display generator.
