Outline of Final Research Achievements

In order to control the Arc 3D display images with smooth movement parallax by applied voltages, we have estimated the directional scattering characteristics and realized appropriate liquid-crystal active device. In contrast to conventional devices by which continuous slopes are used for deflecting light beams, the tips of prism structures can be utilized for directional scattering in our liquid-crystal device. By using our liquid-crystal device, the directional scattering for Arc 3D display can be successfully switched on/off when applied voltage frequency is changed. Moreover, we found that angle distributions of directional scattering strongly depend on tip angles of prism structures.
Thus, basic technologies can be successfully obtained for liquid-crystal active device of Arc 3D display.
