ILLUMINATING OPTIC SYSTEM HAVING BICOLOR MIRROR WHEEL AND IMAGE DISPLAY DEVICE INCLUDING THE SAME

摘要

PURPOSE: An illumination optical system having a bicolor mirror wheel and an image display device including the same are provided to remove an optical loss and enhance the resolution by splitting the light, spatially and temporally. CONSTITUTION: An illumination optical system having a bicolor mirror wheel includes a light source(401) and a bicolor mirror wheel(407). The light source(401) is used for outputting the light. The bicolor mirror wheel(407) includes a plurality of bicolor mirrors. Each bicolor mirror is formed with three segments in order to separate three-color rays from the incident rays of the light source(401). The number of the bicolor mirrors is equal to the number of the segments. The three-color rays are formed with red, green, and blue color rays. The segments corresponding to the bicolor mirrors are used for reflecting different color rays, respectively.
