Development of the 3D adapter using an optical grating film for stereoscopic viewing

摘要

We developed a 3D display using an LCD display panel and a grating film for stereoscopic viewing. The display screen is divided in half in order that left and right regions provide the stereoscopic images for left and right eyes. Because both stereoscopic images are not in the same position, it is difficult for the observer to view the 3D image by the stereoviewing. We solved this problem using a polarized LCD panel and a grating film. The optical grating film shifts both left and right images to the same position. As the result, the observer can watch overlapped stereoscopic images for left and right eyes.
