ABSTRACT W?i s8r:
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV U-!+Cxjs
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of .h O ) R.
the system, and it directly affects final performance, so the design of good color performance, high brightness and pD;'uEFBQ
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light $ <'i+kK
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as /=4 m4
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design &ig6\&1
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS $3.hZx>
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end =*<Cw?Gc
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). cXP*?N4C f
Keywords: optical engine, illumination system, projection display, LCoS
