Stereoscopic 3D Display Using a Parallax Polarizer Barrier

Abstract

A display system that requires no special glasses is useful technology for 3D images. Conventional lenticular and parallax barrier display systems have the disadvantages of producing images with divided horizontal resolution and without see-through. We describe, a newly developed, 3D display with a parallax polarizer barrier that can avoid these problems. The advantage of the parallax polarizer barrier is that the resolution of the presented parallax images is much greater than conventional display. This is because the 3D screen can multiplex projected images with both horizontal and vertical polarizations to display stereo views. This 3D screen can be made more easily using a 1/2-wave plate and a polarizer. The trial screen is 10cm square and consists of two 1/2-wave plates using a liquid crystal (LC) cell and a polarizer.
