Liquid crystal display projection system.

摘要

A liquid crystal display projection system for providing improved brightness. A light beam is split by a polarizing beam splitter (20) into two polarized beams having substantially orthogonal polarizations. Each beam is reflected by a mirror (40, 42) toward an opposite side of a liquid crystal display (30), so that the two beams pass through the display in opposite directions. The two beams are then reflected by the mirrors back toward the polarizing beam splitter, where they are recombined into a single beam for projection onto a screen. <IMAGE>
