Description
technical field [0001] The invention relates to a liquid crystal display device and a driving method thereof. Background technique [0002] The liquid crystal in the liquid crystal display device itself does not have luminescent properties, and it uses an electric field to control the twisting of the liquid crystal molecules to realize the passage or non-passage of light, so as to achieve the purpose of display. The liquid crystal driving method of the traditional liquid crystal display device is the twisted line mode, but its viewing angle range is relatively narrow, that is, different display effects will be observed when viewing the picture from different angles. In order to solve the problem of narrow viewing angle of the twisted steering mode liquid crystal display device, the industry proposes a four-domain vertical alignment type liquid crystal display device. By setting a plurality of "<" shaped protrusions and grooves between two substrates, each pixel The unit ...
