ABSTRACT EIRf6jL
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV ]O."M"B
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of $((<le5-)
the system, and it directly affects final performance, so the design of good color performance, high brightness and @!$NUY8,A#
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light x-<dJ}`
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as ~a $%
a
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design BlUY9`VWh@
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS $$@Tg kg?o
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end J*k4&l
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). >@" j9
