The case for color-filter-on-chip lcos

摘要

Liquid-crystal-on-silicon (LCOS) technology has not been too successful in penetrating the rear-projection-television (RPTV) market. One main reason is that existing LCOS solutions are too expensive and the optical engine too complicated. Recently, we have disclosed a new LCOS technology based on inte- grated color filters (CF_s) that we have developed at Integrated Microdisplays, Ltd. [U.S. Patent No. 6,793,344; SID Symposium Digest Tech. Papers 36, 1302-1305 and 880-883 (2005)]. I genuinely believe that color-filter-on-chip LCOS (CF-LCOS) technology offers an excellent alternative approach to LCOS RPTV.
