Abstract

The invention relates to a driving method of a display panel and a display device. The method comprises the steps of dividing the sub-pixels of the display panel into a plurality of sub-pixel groups;selecting set color sub-pixels, of which the gamma value needs to be adjusted according to the color characteristic of the sub-pixel group for each sub-pixel group, and adjusting the gamma values of the set color sub-pixels of each sub-pixel group. According to the driving method of the display panel and the display device, the gamma values can be independently adjusted for each block. The picturequality of the positive visual angle and the side visual angle can be taken into consideration. In addition, the set color sub-pixels needing to be adjusted are selected according to the color characteristics of the sub-pixel groups, and then the gamma values of the set color sub-pixels are adjusted. The color cast phenomenon caused by the fact that the RGB brightness proportion is not uniform under the low driving voltage in the side view angle can be effectively solved, so that the display effect of the display panel is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving method of a display panel and a display device. Background technique [0002] Traditional large-size liquid crystal display panels usually use negative VA (Vertical Alignment, vertical alignment) liquid crystal or IPS (In-Plane Switching, in-plane conversion) liquid crystal technology. Compared with IPS liquid crystal technology, VA liquid crystal technology has a higher production rate. The advantages of efficiency and low manufacturing cost, but compared with IPS liquid crystal technology, there are obvious defects in optical properties in optical properties, especially in the case of large-size panels that require a larger viewing angle for commercial applications. [0003] The tendency of each sub-pixel brightness saturation (that is, the curve tends to be flat) increases rapidly at the side viewing angle of the traditional VA-type liquid crystal display pa...
