ABSTRACT uGoySt&;(
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV R>C^duos.
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of o[A y2"e?
the system, and it directly affects final performance, so the design of good color performance, high brightness and y^u9Ttf{
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light e> zv+9'Q
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as ;q"Yz-3
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design Y5/SbQYf1
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS %&Fsk]T%:
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end hx.ln6=4
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). Yl$R$u)
