Angular dependence of the performance of stereoscopic liquid-crystal- display (LCD) television using shutter glasses (SG)

3-D cross-talk typically represents the ratio of image overlap between the left and right views. For stereoscopic LCDs using shutter-glasses technology, 3-D cross-talk for stereoscopic LCD TV with a diagonal size of 46 in. and vertical alignment (VA) mode was measured to change from 1% to 10% when the stereoscopic display is rotated around the vertical axis. Input signals consist of the left and right images that include patterns of different amounts of binocular disparity and various gray levels. Ghost-like artifacts are observed. Furthermore, intensities of these artifacts are observed to change as the stereoscopic display is rotated about the vertical axis. The temporal luminance of the LCD used in stereoscopic TV was found to be dependent on the viewing direction and can be considered as one cause of the phenomenon of angular dependence of performance for stereoscopic displays.
