Abstract

AbstractAn efficient and economical LCOS optical engine has been designed for high definition rear projection television. The design uses a 3M™ VikuitiT Optical Core comprising three Cartesian PBSs and an X‐Cube color combiner. The first prototype engine built with this core delivers 400 lm color corrected, near 9000K color temperature with contrast over 1000:1, using a 100W lamp without polarization conversion.
