ABSTRACT +r"$?bw '
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV rKq]zHgpo
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of tam/FzVw
the system, and it directly affects final performance, so the design of good color performance, high brightness and zt6ep=
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light \aozecpC`
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as )I9(WV x!]
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design ^)I:82"|?
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS $r_ gFv
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end HB:i0m2fJW
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). %m`QnRX?D
