Paper Abstract

Since the development of the liquid crystal display (LCD) projector, several features have been improved to realize better quality and performance. The two points listed below have achieved especially satisfying levels: 1. efficiency of utilization of white light source 2. color uniformity As a result an LCD projector with a brightness of more than 70 lumens, and color uniformity characterized by a variation of u' & v' within 0.04 at the peak white level has been developed.
