Abstract

The embodiment of the present application provides a display panel driving method and driving device and a display device. The method comprises the steps of calculating an average gray scale value ofan original pixel unit in each sub-region of the display panel, and then judging whether the average gray scale value is greater than a preset gray scale threshold value, if the average gray scale value is greater than a preset gray scale threshold value, determining a pixel voltage correction value of the sub-region according to a conversion relationship between the average gray scale value and apreset pixel voltage, and setting the pixel voltage correction value as a pixel voltage value of an original pixel unit in the sub-region. Thus, the pixel voltage in the display panel is adjusted toachieve the effect of reducing the color deviation of the display panel, and the problem that the brightness of the large viewing angle of the existing VA-type liquid crystal panel technology will saturate rapidly with the increase of the driving voltage, and the picture quality of the display panel will be distorted when the large viewing angle of the display panel is large is solved.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a driving method, a driving device and a display device of a display panel. Background technique [0002] Existing large-size liquid crystal display panels usually use Vertical Alignment (Vertical Alignment, VA) type liquid crystal panels or in-plane switching (In-Plane Switching, IPS) type liquid crystal panels. Compared with IPS type liquid crystal panel technology, VA type liquid crystal panel technology has The advantages of higher production efficiency and lower manufacturing costs. [0003] However, the existing VA-type liquid crystal panel technology will quickly saturate when the brightness of the large viewing angle increases with the increase of the driving voltage, resulting in distortion of the image quality of the display panel at a large viewing angle, which reduces user experience. Contents of the invention [0004] The present application...
