ABSTRACT t`A5wqm  
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV Gt?ckMB  
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of I*8_5?)g<  
the system, and it directly affects final performance, so the design of good color performance, high brightness and HLDg_ On8  
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light (8.|q6Nww  
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as 5,WDmhJ  
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design 0CUUgwA/  
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS L+"5g@  
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end i52:<<
