Abstract

The invention provides a liquid crystal grating and a control method thereof, a 3D display panel and a display device. A first grating electrode in the liquid crystal grating comprises a plurality of grating sub-electrodes arranged in an arrayed mode. A second grating electrode is a whole clear electrode. Or, the second grating electrode comprises a plurality of grating sub-electrodes arranged in an arrayed mode. The first grating electrode is a whole transparent electrode. The multiple grating sub-electrodes on each row are connected with a row driving line through a plurality of control switches. The multiple grating sub-electrodes on each column are connected with a column driving line through the multiple control switches. According to the embodiment, the electrode pattern on the grating electrode is designed into the mode that the multiple grating sub-electrodes are distributed in the arrayed mode, the row driving line or the column driving line is controlled to apply an electric signal alternately, the liquid crystal layer is pervious to light partially and not pervious to light partially, slits are formed at intervals, electric control signals are used for adjusting the shape and direction of gratings formed on the liquid crystal layer, and therefore transverse or longitudinal random switching o the 3D display effect is achieved.

Description

technical field [0001] The invention relates to the technical field of 3D display, in particular to a liquid crystal grating and a control method thereof, a 3D display panel and a display device. Background technique [0002] At present, with the continuous development of liquid crystal display technology, the application of naked-eye 3D technology is also becoming more and more mature. The specific implementation method is to assemble a grating module composed of a switch liquid crystal screen, a polarizing film and a polymer liquid crystal layer on the surface of the display panel. In the three-dimensional display mode, under certain working conditions, the liquid crystal layer and the polarizing film can form vertical stripes with a width of tens of microns, blocking part of the view, so that the left eye of the viewer only receives the left eye view, and the right eye only receives the view. The right-eye view creates a 3D image effect by separating the visual images of...
