“…Suzuki et al developed a time-sequential 3-D system with an OCB-mode LCD and an OCB-mode active LC shutter glass. 35 In this system, reduced 3-D cross-talk was achieved via a control technology that employed a driving and blinking backlight for black insertion (see Fig. 16).…”

Abstract— Optically compensated bend (OCB) mode is a promising technology, due to its wide range of viewing angles without gray‐scale inversion or color shift, fast response, high contrast ratio, and wide temperature range. This paper summarizes the fundamental characteristics of OCB mode and discusses the development of field‐sequential‐color displays and 3‐D displays for future high‐quality display applications.

“…So, it is technologically possible to make SG 3D TV with the modi-fication of the existing 240-Hz displays, and SG 3D TVs are now available in the market. 4,5,9,10 For large-sized TV applications, users watch TV at various positions. Hence, the viewing direction of the user's position with respect to the TV is not fixed and can affect the display performance.…”

Abstract— 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.

“…Now 3D crosstalk has been measured for active polarizing beam and optically compensated time-sequential stereoscopic 3D LCDs. [2][3] Therefore, the key to introduce the polarizing beam technology into household is to resolve the left and right eye images crosstalk problem. In this paper we developed a new 3D LCD BCfl1 display mode based on backlight control to avoid the crosstalk in 3D display.…”

In this paper a new three-dimensional (3D) liquid crystal display (LCD) display mode based on backlight control is presented to avoid the left and right eye images crosstalk in 3D display. There are two major issues in this new black frame 3D display mode. One is continuously playing every frame images twice. The other is controlling the backlight switch periodically. First, this paper explains the cause of the left and right eye images crosstalk, and presents a solution to avoid this problem. Then, we propose to play the entire frame images twice by repeating each frame image after it was played instead of playing the left images and the right images frame by frame alternately. Finally, the backlight is switched periodically instead of turned on all the time. The backlight is turned off while a frame of image is played for the first time, then turned on during the second time, after that it will be turned off again and run the next period with the next frame of image start to refresh. Controlling the backlight switch periodically like this is the key to achieve the black frame 3D display mode. This mode can not only achieve better 3D display effect by avoid the left and right image crosstalk, but also save the backlight power consumption. Theoretical analysis and experiments show that our method is reasonable and efficient.
