摘要：An optical projection system can receive a red light beam, green light beam, andblue light beam. The optical projection system includes a color-combination prism, andthe light beams respectively enter the color-combination prism from three surfaces andare combined into a mixed light beam, which exits from another surface. A projection lens
set receives the mixed light beam to perform the projection. Each of the light beamsfurther includes a liquid crystal reflection panel and a wire grid polarizer (WGP). Theliquid crystal reflection panel is parallel to the corresponding surfaces of the color-combination prism. In the design, before the light beam entering the color-combinationprism, they are first reflected by the WGP onto the liquid crystal reflection panel, and theliquid crystal reflection panels respectively with a polarizing state reflect the light beams,passing through the WGP and directly propagating toward the color-combination prism.
