Research Abstract

We developed the high-resolution autostereoscopic 3D display system based on the iris-plane dividing technology. We electrically controlled the observation area discretely in the direction of the depth without any mechanical parts by changing the position of activated LC cell according to the visual distance. We also developed the front diffusing film which maintains the polarization state and has a top-hat light diffusing distribution, wide-viewing angle OCB-mode liquid crystal shutter and realized high light efficiency and high luminance uniformity. We confirmed that that our 3D display successfully produced high-quality stereoscopic images without cross-talk noise.
