摘要

We have developed an autostereoscopic multi view display with 36view using 15.1" ultra-high resolution LCD. The resolution of LCD used for experiment is QUXGA of 3200×2400. RGB sub pixels are aligned as vertical lines and size of each sub pixel is 0.032 mm by 0.096mm. Parallax barrier are slanted at the angle of tan~(-1)(1/6) = 9.46 degree and placed before LCD panel to generate viewing zones. Barrier patterns repeated approximately for every 6 pixels of LCD. So, the numbers of pixels decrease by six along the horizontal direction and the vertical direction. Nominal 3D resolution becomes (3200/6) × (2400/6) = 533 × 400. In slanted barrier configuration, the angular luminance profile for each zone overlaps each other. For the case of 2view 3D system, cross-talk between left eye and right eye zone deteriorates 3D image quality. However for multi view 3D, cross-talk between adjacent zones does not always bring about negative effects as image differences between adjacent zones are rather small. As viewers can see pixels from multiple viewing zones at one place, viewers feel 3D image of higher resolution than nominal 533×400 resolutions. Tested 3D images are made by computer graphics, in which camera position and depth of 3D objects are varied. Smooth motion parallax is observed for the limited depth range of 3D object. As depth of 3D object increases, 3D objects are observed not one image but as overlapped multiple images and image flipping becomes noticeable. We changed the barrier conditions so that horizontal angles between each zone are different and 3D image qualities were compared. For each barrier condition of different horizontal angle between viewing zones, we find an acceptable range of 3D object depth and camera displacement between each zone for computer generated images.
