ABSTRACT PMpq>$6b7
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV YR*gO TD
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of y^,Q M[ &
the system, and it directly affects final performance, so the design of good color performance, high brightness and p<=Lh47 =
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light !8[T*'LJ-
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as ]c~yMA+]FZ
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design $TmEVC^ 0
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS X!qK[b@ Z
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end 9-/q-,
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). DH
