Hollow cavity light guide for the distribution of collimated light to a liquid crystal display |
摘要 |
An optical light guide comprising optical elements enclosing a hollow cavity is configured to uniformly distribute homogenized collimated light to a liquid crystal display. The optical light guide includes a beam splitting structure covering the entrance aperture of the light guide, a retarder and specular reflector on the face of the light guide opposite the entrance aperture, an exit aperture orthogonal to the entrance aperture with a reflective polarizer and a beam directing structure over the exit aperture, and a specular reflector on the bottom of the light guide opposite the exit aperture. |
