Abstract: In an autostereoscopic display apparatus comprising a liquid crystal spatial light modulator having an array of pixels of different colors, each pixel comprising plural domains of different polar alignments, and a parallax element comprising an array of optical elements having geometric axes extending in parallel across the spatial light modulator in an inclined direction, the domains are shaped to improve the angular contrast uniformity. For each individual domain, a notional line parallel to the geometric axes of the optical elements of the parallax element has a total length of intersection with the individual domain, summed over adjacent pixels of the same color, is the same for all positions of the notional line. The total length of intersection for different domains is proportional to the area of the individual domains.

Abstract: An autostereoscopic display system comprised of an array of vertically oriented narrow light sources and a spatial light modulator, (SLM), disposed between the lights and viewers, whereby light rays originating from the lights and passing through the SLM are vertically dispersed by a vertical dispersion panel. The lights are sequentially flashed, sending light through the SLM where selected full height narrow vertical picture lines, VPL's, are made briefly transmissive while the remainder of the SLM remains dark, projecting vertically oriented sheets of light through selected VPL's toward selected eyes. The light sheets are sufficiently narrow as to enter a left or right eye but not both, while the entire height of selected VPL's is visible due to said vertical dispersion. The process rapidly repeats for all VPL's and all array lights, alternating between right/left SLM scenes each projected into appropriately selected eyes resulting in a 3D image.

Abstract: Moiré generated in an autostereoscopic display utilizing a parallax barrier method is cancelled. The interval between visible light transmitting sections that are abutting in the horizontal direction of a parallax barrier is determined using: the average number of subpixels constituting one pixel for three-dimensional display in one row in the horizontal direction; the width of a subpixel, which forms a display; the distance from a predetermined diagonal moiré canceling position to the parallax barrier; the number of viewpoints of a video image used for displaying an autostereoscopic video image; and the distance (Z) from the image display surface of the display to the parallax barrier.

Abstract: Stereoscopic video content is reproduced to obtain a first pair of images with mutual parallax producing a stereoscopic effect. A first stereoscopic adjustment on the first pair of images is carried out to obtain a second pair of images. A second stereoscopic adjustment on the second pair of images is carried out to obtain a third pair of images, which are displayed on a screen to respective eyes of the viewer. The first stereoscopic adjustment is carried out differently for different video sources. The second stereoscopic adjustment is the same for all sources. The combination of the first and second stereoscopic adjustments enables content from different sources to be displayed with an appropriate stereoscopic adjustment for each source.
