Abstract
An optical unit (20, 30) for color projection display system that has three SLMs (21, 31) and three projection lenses (27, 37). Each SLM (21, 31) receives light of a different primary color, which it modulates to form images for that color. Each SLM (21, 31) and its associated projection lens (27, 37) provides a 'channel' for that color of the final image, with the channels being converged out of the projection lenses (27, 37) to the viewing screen.
