Abstract: A back-lighted autostereoscopic display. A uniform light is emitted from a plane light source. A polarization plate is disposed in front of the plane light source to polarize the uniform light into a polarized light. A micro-moving window device is disposed in front of the polarization plate to selectively change the polarity of the polarized light into another type of polarization. A micro-optical device is located in front of the micro-moving window device, thereby both the polarized light changed and unchanged pass through the micro-optical device to travel further. An imaging apparatus is located in front of the micro-optical device, so that the lights are converged into the eyes of an observer. A liquid crystal display panel with a patterned half-wavelength phase retarder according to the even rows and odd rows of the interlaced image displayed on the liquid crystal display is located in front of the imaging apparatus to project the stereo-image to the observer.
