Abstract
A display including a screen layer for displaying a unified image to a viewer on a viewing side of the screen layer that is opposite a backside of the screen layer, and an illumination layer having an array of light sources. Each light source in the array is configured to emit a divergent projection beam having a limited angular spread. A display layer is disposed between the screen layer and the illumination layer, and includes a matrix of pixlets, a spacing region disposed between the pixlets in the matrix, wherein the array of light sources are positioned to emit the divergent projection beams having limited angular spread to project sub-images displayed by the pixlets as magnified sub-images on the backside of the screen layer, the magnified sub-images to combine to form a substantially seamless unified image, and one or more components positioned on the display layer in the spacing region.
