The invention discloses a liquid crystal grating, a driving method of the liquid crystal grating and a three-dimensional display device; and aims at solving the problem that existing liquid crystal gratings are prone to cause crosstalk during three-dimensional display. The liquid crystal grating of the embodiment comprises a first substrate, a second substrate and a liquid crystal layer arranged between the first substrate and the second substrate, and the first substrate and / or the second substrate are provided with a plurality of bar-shaped electrode structures arranged at equal intervals. Each bar-shaped electrode structure is connected with a driving circuit of the liquid crystal grating through different control lines, and under a three-dimensional display mode, the liquid crystal grating adjusts size of a light transmitting area corresponding to each current position information according to the current position information of each light transmitting area corresponding to own left eyes and right eyes of watchers. The light transmitting area of the embodiment can effectively reduce crosstalk and improve visual angles of the watchers under the three-dimensional display mode.
Description
technical field [0001] The present invention relates to the technical field of stereoscopic display, in particular to a liquid crystal grating, a driving method thereof, and a stereoscopic display device. Background technique [0002] The working principle of three-dimensional (3D) display technology is: for the same scene, the left eye and the right eye of the viewer receive images respectively, and the distance between the two eyes of the viewer in the horizontal direction (that is, the interpupillary distance, about 65mm), There is a slight difference in the perspective of the two eyes. Due to this difference, the images observed by the left eye and the right eye of the viewer will also be slightly different. This difference is called "binocular parallax". The different images observed by the eyes constitute a pair of "stereoscopic image pairs". After the "stereoscopic image pairs" are fused by the visual cortex of the brain, a stereoscopic effect is formed. [0003] Whe...
