Abstract

Abstract

The paper introduces the mechanism of liquid-crystal-on-silicon(LCOS) display. tendue value is used to illustrate luminous flux and optical efficiency, and the relation between optical efficiency and étendue value is analyzed. Zemax and Tracepro are used in the design simulation. Experimental results show that the optical engine has advantages such as small size, low étendue, high light uniformity of more than 92% and high energy efficiency of 56%, and can meet the needs of projection display.
