Paper Abstract

The goals of our research are to realize stereoscopic large displays for the general public in the open air. These goals impose certain design constraints. It is preferable to view stereoscopic images without any special glasses. Multiple viewing areas are necessary to crowds of viewers. The thickness of the stereoscopic large display is a problem for installations. We have developed a stereoscopic full color LED display using parallax barrier and demonstrated multiple viewing areas. However, the thickness of that stereoscopic display, which is consisted of 8-mm pitch LED panel, becomes over 2 min the case that the viewing distance is designed for 20 m. In order to reduce the thickness of stereoscopic LED display, we propose use of dual lenticular sheets. The first lenticular sheet performs multiple imaging, which allows multiple viewing areas without diffusion screen. The second lenticular sheets separates the raster images into the right and left eye positions. The thickness, which is defined as the distance between the LED panel and the second lenticular sheet, can be reduced below 50cm for the viewing distance of 20 m. Optimal parameters are discussed to reduce the thickness.
