Abstract

A compact LCD projection display system and its optical performance are discussed in this paper. In order to improve optical performance, two flyingeye lens have been employed in the system. It can improve the brightness uniformity of display image. Also, a polarized light transformer, which involves two functions: polarizing light radiation and converting unpolarized light into the same polarization direction light beam for LCD panels, has been developed to increase the optical efficiency and contrast ratio. Moreover, color separation and combination system has been designed and developed. Under these construction, the system with good optical performance and outstanding picture quality has been achieved.
