ABSTRACT $+<X 1
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV
0O>8DX
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of .Jz$)R
the system, and it directly affects final performance, so the design of good color performance, high brightness and N2VF_[l
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light OH28H),}
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as ! G%LYHx
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design 2oAPJUPOJ
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS ;C%D+"l1g
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end R.R(|!w>
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). #(jozl_8
