Abstract

The invention provides a liquid crystal display device and a driving method thereof. A first pixel holding voltage and a second pixel holding voltage output by positive and negative half-cycle pixel electrodes are not symmetrical about a common voltage output by a common electrode, so that gray scale inversion of positive and negative half-cycle images displayed by the liquid crystal display device is compensated; and the skin whitening problem in side view is improved, so that the display view angle problem of the liquid crystal display device is solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a liquid crystal display device and a driving method thereof. Background technique [0002] Vertical Alignment (Vertical Alignment, VA) mode liquid crystal display device because of the birefringence characteristics of liquid crystal, compared with twisted nematic (Twisted Nematic, TN) mode liquid crystal display device, VA mode liquid crystal display device is prone to skin color whitening during the display process (color washout) problem. At present, the commonly used multi-domain pixel design can improve the whitening of the skin color to a certain extent, but in order to enhance the image quality, it is still necessary to increase the viewing angle of the VA mode liquid crystal display device. [0003] Therefore, it is necessary to propose a technical solution to solve the viewing angle problem of the VA mode liquid crystal display device. Contents of the inven...
