Embodiment Construction

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0033] see Figure 6 to Figure 10 , the present embodiment provides a display panel, the display panel includes N partitioned sub-pixels, the grayscale state of each subpixel includes high grayscale H and low grayscale L; the grayscale state of the subpixels in the same partition remains N consecutive frames, and the grayscale state switching of sub-pixels in one partition is performed in the same frame; wherein, N is a positive integer greater than or equal to 2.

Abstract

The present application discloses a driving method of a display panel, a display panel and a liquid crystal display device. The display panel includes sub-pixels in N partitions, and the grayscale state of each subpixel includes high grayscale and low grayscale. The subpixels in the same partition The gray-scale state of N is maintained for N consecutive frames, and the gray-scale state switching of sub-pixels in a partition in the same frame can not only reduce the brightness change range between adjacent frames, but also increase the brightness change frequency, thereby reducing or Avoid flickering.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a method for driving a display panel, a display panel, and a liquid crystal display device. Background technique [0002] The display panel adopts the time-domain viewing angle compensation algorithm to effectively improve or remove the graininess of the display screen. When the liquid crystal in the display panel responds slowly, the grayscale state switching of each frame performed by the time-domain viewing angle compensation algorithm cannot achieve the ideal large-scale display. The effect of improving the effect of character deviation; if the number of frames for maintaining the grayscale state of each sub-pixel is prolonged in a scene where the refresh rate of the display panel is low, it will easily lead to a more obvious flickering phenomenon. [0003] For example, if figure 1 As shown, in one frame of the display panel, the grayscale state of all sub-pix...
