Patent ID: 8711478

Claim:
A stereoscopic display comprising: a display panel including a display surface in which sub-pixels of a plurality of colors are two-dimensionally arranged in a predetermined arrangement pattern, and displaying a plurality of parallax images corresponding to the number of viewpoints in stereoscopic vision, the parallax images being combined into one screen while spatially separated from one another; and a parallax barrier arranged to face the display surface, including a barrier pattern configured of transmission sections allowing display image light from the display panel to pass therethrough and a shielding section shielding the display image light, and optically separating, with the barrier pattern, the parallax images displayed on the display panel from one another so as to achieve stereoscopic vision, wherein the display surface of the display panel has a vertical length different from a horizontal length thereof, the predetermined arrangement pattern of the sub-pixels in the display panel and the barrier pattern in the parallax barrier are configured in such a manner that stereoscopic vision is achieved when the display panel and the parallax barrier are both in a first arrangement state and in a second arrangement state, the first arrangement state and the second arrangement state having such a positional relationship that vertical direction and horizontal direction are interchanged with each other, wherein the transmission sections in adjacent rows or columns of the parallax barrier are arranged in a staggered configuration in such a manner that each of the transmission sections in a first row or column is arranged at a position shifted from the corresponding transmission section in an adjacent second row or column by an offset distance of a predetermined number of sub-pixels, wherein in the second arrangement state, stereoscopic vision is achieved by using each sub-pixel in the horizontal direction and using sub-pixels in every other vertical line in the vertical direction, wherein the sub-pixels are arranged in a repeating pattern of four different pixel groups that are arranged in triangular shapes and that are offset from one another, and wherein in the second arrangement state, stereoscopic vision from two viewpoints is achieved with use of first pixel groups for the first viewpoint and third pixel groups for the third viewpoint, and the barrier pattern is configured to shield the second and fourth pixel groups.
