Patent Images
1. An image display apparatus, comprising:
- an emissive display having plural pixels;
at least one source of ultraviolet (UV) light; and
a pixel activation mechanism scanning the UV light onto the pixels in response to a demanded image, wherein the display includes at least one substrate, plural pixels being established on the substrate, each pixel being established by respective red, green, and blue subpixels, at least one light refracting layer covering the pixels and opposed to the substrate.

Abstract
A large screen emissive display operating at atmospheric pressure includes pixels, the red, green, and blue subpixels of which are excited by UV laser light scanned onto the subpixels by a pixel activation mechanism. The pixel activation mechanism includes three grating light valves (GLVs) that are controlled by a processor in response to a demanded image to modulate the UV light as appropriate to produce the demanded image.
