An autostereoscopic display system with four viewpoints in full resolution using active anaglyph parallax barrier

In this paper, we propose an autostereoscopic display system based on active anaglyph parallax barrier, which provides four viewpoints in full resolution. This system is realized with 120Hz displays and requires no special optical devices. With the four viewpoints achieved, a smoother multi-view experience can be achieved when involving head tracking. In addition, this system can be used for two-viewpoint autostereoscopy that allows more freedom of movement than that of a conventional parallax barrier system. We made a prototype system with two 120Hz displays and successfully showed four viewpoints.
