ABSTRACT IFHgD}kp%#
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV bYRQI=gW':
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of G5C#i7cpm
the system, and it directly affects final performance, so the design of good color performance, high brightness and XmE_ F
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light ?Vb=4B{~
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as U^WQWa
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design ePFC$kMn
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS )[a?J,
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end .>cL/KaP
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). i1kh@s~8UC
