Paper Abstract

The step barrier technology with multiple parallax images has overcome the problem of conventional parallax barrier system that the image quality of each image deteriorates only in the horizontal direction. The step barrier distributes the resolution problem both to the horizontal and the vertical directions. The system has a simple structure, which consists of a flat-panel display and a step barrier. The apertures of the step barrier are not stripes but tiny rectangles that are arranged in the shape of stairs, and the sub-pixels of each image have the same arrangement. And three image processes for the system applicable to computer graphics and real image have been proposed. Then, two types of 3-D displays were developed, 22-inch model and 50-inch model. The 22-inch model employs a very high-definition liquid crystal display of 3840 x 2400 pixels. The number of parallax images is seven and the resolution of one image is 1646 x 800. The 50-inch model has four viewing points on the plasma display panel of 1280 x 768 pixels. It can provide stereoscopic animations and the resolution of one image is 960 x 256 pixels. Moreover, the structural or electric 2-D 3-D compatible system was developed.
