Abstract:
1. An optical display device comprising: a substrate comprising a source of light, the light from the source of light including a plurality of primary colors; a modulation array comprising a plurality of modulation elements arranged to modulate light received from the source of light; a reflective color filter array comprising a plurality of color filters, each of the plurality of color filters arranged to correspond to a respective element of the modulation array, each of the plurality of color filters transmitting light having one of the primary colors and reflecting light of the remaining light having other of the primary colors back to the substrate, the reflective color filter array arranged relative to the substrate such that there are no layers winch substantially absorb light of the primary colors between the substrate and the reflective color filter array; and a reflective panel winch reflects the reflected light having the primary colors back towards the reflective color filter array, wherein the modulation array comprises a reflective polarizer, and wherein the reflective color filter array is disposed between the reflective polarizer and the substrate.
