Abstract

This paper proposes a super-multiview autostereoscopic display with a full HD resolution. A super-multiview display, where multiple views are generated around the eyes to stimulate focal accommodation, requires generation of images for many viewpoints. When we apply time-division multiplexing, the number of views can be increased without losing spatial resolutions, while flickers stand out as the number of time-division increases. To attain more views with the same refresh rate, we set two LCD panels so that they may face the opposite directions. In this way, the order of color filter is reversed and the light rays of different colors are directed to different orientations. Each color creates a different directional light to achieve three fold views. To extend the viewing zone in the depth direction, we introduce adaptive time-division, where quadruplexing is applied when the viewer is farthest, quintuplexing is applied when the viewer is in the middle, and sextuplexing is applied when the viewer is nearest. Expansion of viewing zone and the effect of focal induction are confirmed by the experiments using a prototype system based on the proposed method.
