Paper Abstract

Liquid-crystal projection displays (LCPD) have been in production for many years, and have demonstrated performance equal to HDTV requirements. Projection CRT displays are cheaper to manufacture, making it difficult for LCPDs to compete in the consumer market. This could change with recent developments in metal halide arc lamps which will lead to smaller and cheaper LCPDs. The arc dimensions determine the light source etendue, which is a basic parameter in projector design. The influence of source etendue on the optical efficiency of various LCPDs is assessed with the goal of reducing the diameter of the spatial light modulator (SLM) while maintaining high-efficiency. The SLM diameter is a measure of the manufacturing cost.
