A multi-layer optical structure includes a pixel array layer, an addressing matrix layer, and a micro lens array. The pixel array layer includes an array of quantum dot pixels for emitting an image from a first side of the multi-layer optical structure. The addressing matrix layer adjoins the pixel array layer and includes electrically conductive signal lines to individual address and activate the quantum dot pixels to generate the image. The micro lens array includes micro lenses optically aligned with the quantum dot pixels in an emission path of the image to focus the image. |
