Abstract

In 3-D imaging systems, with a point light source (PLC) array as a backlight illumination and viewing zone forming, the finite size of the light-emitting surface of each PLC in the array and mismatch between the array period and pixel cell pitch limits the region of individual view image to a small portion of the viewing zone cross section (VZCS). The portion becomes smaller as the size approaches that of a pixel for an individual view image in the pixel cell, and/or the fractional size of the pixel becomes smaller. As a consequence, the VZCS becomes filled with viewing regions for mixed images of two adjacent view images. Hence, the effective number of different images which can be viewed at VZCS could be increased around two times that of the total different view images displayed on the display panel.
