OPTICAL CONFIGURATIONS IN A TILEABLE DISPLAY APPARATUS

摘要

A display apparatus including a screen layer for displaying a unified image to a viewer and an illumination layer having an array of light sources. Each light source emits a light beam. An array of optical elements, each coupled to a corresponding light source in the array of light sources, is disposed between the screen layer and the illumination layer. The display layer includes a matrix of pixlets and a spacing region disposed between the pixlets in the matrix, wherein the array of light sources emit their light beams through the array of optical elements, wherein each optical element is configured to shape the received light beam into a divergent projection beam having a 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 the unified image that is substantially seamless.

1. A display apparatus comprising:
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; an illumination layer having an array of light sources, wherein each light source emits a light beam; an array of optical elements, each optical element optically coupled to a corresponding light source in the array of light sources; a display layer disposed between the screen layer and the illumination layer, the display layer comprising:
a matrix of pixlets, anda spacing region disposed between the pixlets in the matrix, wherein the array of light sources are positioned to emit their light beams through the array of optical elements, wherein each optical element is configured to shape the received light beam into a divergent projection beam having a 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 the unified image that is substantially seamless.
