Parallax Barrier 3D Display for Viewing Full Images

Abstract

A display system that does not require viewers to wear special glasses to see 3D images is useful technology. Conventional lenticular and parallax-barrier display systems have disadvantages in that images have divided horizontal resolution. We describe a thin stereoscopic 3D display with a parallax polarizer barrier. The advantage of the parallax polarizer barrier is that the resolution of presented parallax images is much greater than that possible with conventional displays. This compact display has two LCD panels to present stereo views and control polarization. It has twice the 3D image resolution, because the LCD image plane can multiplex images with horizontal and vertical polarization to display stereo views.
