Abstract: A screen panel includes a rigid glass, a lenticular lens and a Fresnel lens laminated with each other, and the edges of the screen panel are sealed. An air evacuation path is formed between the lenses by wires inserted between the contact surfaces of the lenses, or by convexes or concaves previously formed on one of the contact surfaces. Because of the provision of the air evacuation path, the air between the lenses of the screen panel is sufficiently evacuated, and the lenses can closely attached to each other. Therefore, the flatness of the screen panel can be enhanced, and the degradation of the image quality can be prevented.

Abstract: A display apparatus includes an emissive screen having luminescent pixels that are addressed solely by a laser addressing system. Each pixel includes a luminescent region located next to a photocathode. When struck by the laser beam, free electrons are created that are accelerated by an applied high voltage field from the photocathode to the luminescent region, thereby causing the luminescent region to emit visible light with a brightness (energy) that is substantially higher than the energy of the addressing beam. Apertures are optionally provided in hexagonal luminescent regions to relax beam-scanning requirements. Optional millichannel plates (crude versions of 2nd generation night vision system Microchannel plates) are provided to enhance photon multiplication. A position sensitive device is implemented using the photocathode or photoanode (luminescent) material to facilitate the scanning and modulating process.
