Patent ID: 8508830

Claim:
A multi-layer optical structure, the multi-layer optical structure comprising: a pixel array layer including an array of quantum dot pixels for emitting an image from a first side of the multi-layer optical structure; an addressing matrix layer adjoining the pixel array layer including electrically conductive signal lines to individual address and activate the quantum dot pixels to generate the image; a micro lens array including micro lenses optically aligned with the quantum dot pixels in an emission path of the image to focus the image; and a common electrode plane adjoining the pixel array layer on an opposite side of the pixel array layer as the addressing matrix layer, wherein the common electrode plane extends adjacent to a plurality of the quantum dot pixels, wherein the common electrode plane and the addressing matrix layer selectively electrically pump the array of quantum dot pixels to cause selected quantum dots to generate light, wherein the micro lens array is disposed over the common electrode plane and the common electrode plane is disposed between the micro lens array and the pixel array layer, wherein the pixel array layer, the addressing matrix layer, and the common electrode plane are at least semi-transparent to permit external light to pass through the multi-layer optical structure and the image emitted from the pixel array layer to pass out through the common electrode plane.
