Abstract
We developed a flat panel display having a slanted subpixel arrangement suitable for a multi-view display. A set of 3M × N subpixels (M × N subpixels for each R, G, and B color) is combined with one of the cylindrical lenses constituting a lenticular sheet to construct a three-dimensional pixel. Subpixels with the same color in each three-dimensional pixel have different horizontal positions, and these R, G, and B subpixels are repeated in the horizontal direction. In addition, ray-emitting areas of the subpixels in a three-dimensional pixel are continuous in the horizontal direction for each color. One vertical edge of one subpixel has the same horizontal position as the opposite vertical edge of one of the other subpixels of the same color subpixels. The crosstalk among viewpoints is theoretically zero and a three-dimensional image has no moire. When the horizontal pitch of subpixels is p, the width of a subpixel is 3p/N and the width of the black matrix region between subpixels is (1-3/N)p. This structure is suitable for providing a large number of viewpoints. A mobile three-dimensional display with 16 viewpoints and three-dimensional resolution of 256 × 192 was constructed. The screen size was 2.57 inches. A three-dimensional pixel was composed by 12 × 4 subpixels (M=4 and N=4). The horizontal pitch of subpixels was 17.0 μm and the horizontal width of the black matrix areas was 4.25 μm. The horizontal position of subpixels was shifted 9.56 μ;m between adjacent rows.
