Abstract
A single panel reflective-type color optical engine makes use of a grating matched with a reflecting mirror set for adjusting the traveling directions of three primary color lights or at least a beam-splitting rotating disk and a reflecting mirror to split an incident light into the three primary color lights and separately adjusts their reflected directions and orders, or makes use of three reflecting mirrors with continually varying angles to reflect three primary color lights to adjust their reflected directions and orders, thereby simultaneously projecting the three primary color lights onto different regions of a single panel in the red-green-blue, green-blue-red, and then blue-red-green order. The single panel reflective-type color optical engine can apply to LCOS and DLP reflective-type projection systems, and has the advantages of high brightness, good uniformity, small size, and low price.
