ABSTRACT (yTz^o$t|
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV QKaj4?p$|S
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of K,,@',
the system, and it directly affects final performance, so the design of good color performance, high brightness and oY6|h3T=Q$
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light Z

weight design makes it more competitive. LightTools software has a great many of powerful functions, such as &eS70hq
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design N[bf.5T
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS "oXAIfU#T
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end 9-iB?a7{.
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). >h( rd1
Keywords: optical engine, illumination system, projection display, LCoS
