Abstract

The present invention provides a driving method of a display panel, a display panel and a display device. The driving method of the display panel groups a plurality of pixel units in the display panel, so that each pixel unit includes the same number of sub-pixels, and performs display grayscale switching for each pixel unit in the corresponding switching frame, so that the In each pixel unit, the sub-pixel originally having the first display gray level is switched to have the second display gray level, the sub-pixel originally having the second display gray level is switched to have the first display gray level, and each pixel in the same frame is switched to have the second display gray level. The number of sub-pixels with the first display gray level and the sub-pixels with the second display gray level included in the pixel unit is the same, and the plurality of sub-pixels in the multiple pixel units maintain the first display gray level and the second display gray level. The frame duration is the same.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a driving method of a display panel, a display panel and a display device. Background technique [0002] In high-resolution display panels, the 4-domain pixel structure and the time-domain viewing angle compensation algorithm are often used to improve the viewing angle bias problem. However, the response time of the existing liquid crystal is long, and the switching time of HL (the original pixel grayscale value is replaced by two grayscales with relatively high (H) and relatively low (L) grayscale values) needs to be extended to achieve the effect of improving the viewing angle deviation. . However, prolonging the HL switching time will result in a lower brightness switching frequency during HL switching, which is easy to make the human eye perceive the existence of flickering. SUMMARY OF THE INVENTION [0003] Embodiments of the present invention provide a m...
