A liquid crystal display (LCD) recently comes into common use. It is possible for this display unit to provide the same size of displaying area as the image screen on the panel. To display a stereoscopic image for left and right eyes, the display screen needs to be divided in half and left and right stereoscopic images must be overlaid for easy 3D viewing. The authors had ever developed a stereo image overlapping method which enables both images to be in same position. A grating film can shift an image into any position by adjusting the interval from the original image plane. However an observer must wear the polarized glasses to separate the overlaid stereoscopic images into appropriate eyes. To improve this problem, we developed a glasses-free 3D stereoscopic display using an LCD display panel, a view control film and a grating film for stereoscopic viewing. The observer can watch overlapped stereoscopic images for left and right eyes without special glasses such as polarized glasses.
