ABSTRACT e#(0af8A
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV d QVV0)z
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of cKEf- &~
the system, and it directly affects final performance, so the design of good color performance, high brightness and MUh )
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light 0?qXD O&~
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as >eQ;\j
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design I\&..e0l
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS QZ$9 4XLI
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end H$>D_WeJ
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). \K.i8f,
