ABSTRACT tH(g;flO)  
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV ]P96-x  
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of GP(ze-Yp  
the system, and it directly affects final performance, so the design of good color performance, high brightness and vawS5b;  
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light Ltk-1zhI  
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as :rU,7`sE/  
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design e0M'\'J  
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS 1pz-jo,2'  
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end P @~)
