ABSTRACT J '%
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV Jp0*Y-*Y
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of ];vEj*jCX
the system, and it directly affects final performance, so the design of good color performance, high brightness and i r-= @ @
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light %]zaX-2dm!
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as nisW<Q `uB
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design JS&=V 67[
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS <yxEGjm
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end *A>I)a<:
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). =Z($n: m=*
