Abstract

A brightness-enhanced full-color projection display using optically addressed spatial light modulators (SLMs) with light-scattering mode polymer-dispersed liquid crystal has been developed. The SLM can modulate strong unpolarized light efficiently using the light-scattering effect. The projector using SLM with a Schlieren optical produces bright, high-contrast images. Electrical image compensation of the shading and gamma characteristics of the SLMs carried out in the driving circuits improves the spatial uniformity and gray-scale representation of the projected images. The system projects a bright image of more than 1300 cd/m ² with a high extinction ratio over 130:1 on a 60-inch screen, which can be viewed in a bright living room under normal lighting conditions.
