PROJECTION AUTO-STEREOSCOPIC DISPLAY AND STEREO SCREEN

摘要

A projection auto-stereoscopic display includes an image projector (100) and a stereo screen (200). The image projector (100) projects image. The image includes multiple viewing-zone pictures. The stereo screen (200) receives the image and reflects the image. The stereo screen (200) includes a linear polarizer (202), for receiving the image projected thereon and filtering the image in polarization. A first micro-retarder layer (204) is attached behind over the linear polarizer. A second micro-retarder layer (208) is disposed behind over the first micro-retarder layer (204). A reflection-type polarization preserved diffuser is disposed behind the second micro-retarder layer, for reflecting and diffusing an incident light into various directions.
