A Stereoscopic Display With Wide Viewing Area Using Backlight Division
Details
We suggest a new stereoscopic display system to provide wide viewing area. To enlarge viewing area, the backlight panel is put slanting. It gives freedom of the distance between the lens and lights on the backlight panel. Because of observer-tracking program detects observer's iris, recognizes observer's position by the distance between the eyes of the observer and emits light for position corresponding to observer's eyes, viewing area are also extended. Since lights on the backlight panel focus at the viewing points vertically, a diffusion filter is used to spread light vertically. So a few observers can view stereoscopic images even if they are in different distances at the same time.
