Abstract
An autostereoscopic projection screen with projection displays a stereoscopic image for receiving parallax images of right eye and left eye. The autostereoscopic projection screen includes a polarization-reserved diffuser, a microretarder, a polarizer, and a parallax element. Parallax images of right eye and left eye pass through the polarization-reserved diffuser and the microretarder for transferring their polarization states. Parallax images of right eye and left eye with specific polarization states will pass the polarizer and parallax element for dividing images of right eye and left eye from parallax images. The individual images separately enter viewing zones of right eye and left eye to generate the stereoscopic-image for viewers.
