ABSTRACT 58XZ]Mc0
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV v^ "qr?3V
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of Li]bU
the system, and it directly affects final performance, so the design of good color performance, high brightness and u?" ="-^
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light Q7rBc

weight design makes it more competitive. LightTools software has a great many of powerful functions, such as \_WR:? l
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design EjL]#,QR
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS ^R =`<jx
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end $2\ 8Rn6'
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). {.542}A
