ABSTRACT 7 sv

Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV $_NYu
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of R7u &`
the system, and it directly affects final performance, so the design of good color performance, high brightness and v<

contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light a"gZw9m@
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as nen(
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design v7x%V%K
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS

projection display including illumination system, dividing and recombining of colors system, projection lens. At the end UfcQFT{()
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). f& P'Kxj_
