ABSTRACT ?4A$9H
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV (dgBI}Za
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of .Mb<.R3
the system, and it directly affects final performance, so the design of good color performance, high brightness and (`me}8
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light {$fd?| 9h
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as U1 ;<NUg
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design b"7L

of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS rf= ndjrH
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end Wt

evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). z8-dntkf
Keywords: optical engine, illumination system, projection display, LCoS
