Abstract
An autostereoscopic 3D display device may be configured to set the width of a viewing zone to a proper fraction of the interocular distance while at the same time overlapping the viewing zones with each other. Through this, an autostereoscopic 3D display device allowing the input and output of stereo image data may be implemented to reduce the number of image sources as well as reduce 3D crosstalk. In addition, the autostereoscopic 3D display device may apply view data rendering to extend a 3D viewing zone.
Claims17
An autostereoscopic 3D display device, comprising:
- an image panel comprising a plurality of sub-pixels that collectively output light corresponding to stereo view data, the stereo view data defining a first view image and a second view image;
- and
- a 3D filter disposed on a surface of the image panel, the 3D filter selectively directing portions of the outputted light to a plurality of viewing zones at a viewing distance, wherein the plurality of viewing zones is divided into repeating blocks of m viewing zones, m being an odd integer greater than 4, and, for each block, the portions of the outputted light form instances of the first view image in a first subset of the m viewing zones and instances of the second view image in a second subset of the m viewing zones, and wherein the first subset of the viewing zones has [(m−1)/2] viewing zones and the second subset of the viewing zones has [(m+1/2] viewing zones;
- wherein the plurality of viewing zones are overlapped with each other and a width of each viewing zone is a proper fraction of an interocular distance between an observer's eyes.
