ABSTRACT 9wq%Fnt
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV /5x `TT
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of -8tA~;p
the system, and it directly affects final performance, so the design of good color performance, high brightness and 7@lXN8_f
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light kQ#eWk J,
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as :>X7(&j8
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design h+74W0
$
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS _"sRL} -Z
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end Mt YP3:
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). nUd\4;J#
Keywords: optical engine, illumination system, projection display, LCoS
