Abstract
The invention discloses a three-dimensional display device and a liquid crystal grating and a control method thereof. The liquid crystal grating comprises a first substrate and a second substrate which are oppositely arranged, a liquid crystal layer located between the first substrate and the second substrate, a first substrate electrode located on the first substrate and facing to one surface of the liquid crystal layer and a second substrate electrode located on the second substrate and facing to one surface of the liquid crystal layer. The second substrate electrode comprises a plurality of parallel strip-shaped sub electrodes which are electrically insulated. When the liquid crystal grating performs displaying, a plurality of light-transmitting grating bars and light-shading grating bars which are distributed at intervals are formed, each light-transmitting grating bar comprises a plurality of sequentially adjacent sub electrodes, and each light-shading grating bar comprises a plurality of sequentially adjacent sub electrodes. The light-transmitting grating bars and the light-shading grating bars of the liquid crystal grating can be moved by controlling voltage of the sub electrodes of the second substrate electrode, the deviation of the center point position of the two eye connection line of a viewer and the position of a calibration grating bar is reduced, and the three-dimensional display effect is ensured.
Description
technical field [0001] The present invention relates to the technical field of image display, and more specifically, relates to a three-dimensional display device, a liquid crystal grating and a control method thereof. Background technique [0002] Glasses-free three-dimensional display is a common three-dimensional display method at present. It does not need special polarizer glasses, and only needs to integrate a parallax barrier on the display device to realize three-dimensional display. Since the liquid crystal grating can realize the conversion between three-dimensional and two-dimensional, and is compatible with the preparation process of the liquid crystal display, it occupies a major position in the naked-eye three-dimensional display, and becomes the preferred parallax barrier in the naked-eye three-dimensional display device. [0003] refer to figure 1 , the existing liquid crystal grating includes: a first substrate 001 and a second substrate 002 arranged opposit...
