Embodiment Construction

[0044] In order to better understand the purpose, technical solution and technical effect of the present invention, the present invention will be further explained below in conjunction with the accompanying drawings and embodiments. At the same time, it is stated that the embodiments described below are only used to explain the present invention, and are not intended to limit the present invention

[0045] An embodiment of the present invention provides a method for driving a display panel:

[0046] A method for driving a display panel. The display panel includes a display array, and the display array includes pixel units arranged in an array. The columns formed by the arrangement of each pixel unit are arranged sequentially in the row direction, wherein each pixel unit includes a first pixel unit arranged sequentially in the row direction. , 2, ..., α, α+1, ..., k sub-pixels, where α is greater than or equal to 1 and less than or equal to k.

Abstract

The present invention relates to a driving method and a display device of a display panel. Taking the driving of the pixel units of the 2β frame display array as a cycle, the αth sub-pixel in the pixel unit of the β frame display array is driven in the bright area, and the remaining The αth sub-pixel in the pixel unit of the β frame display array is driven in the dark area. In the pixel units of the 2β frame display array displayed in one cycle of the display array, the α-th sub-pixel of each pixel unit in the pixel units of the 2β frame display array realizes bright area and dark area cancellation. At the same time, the sub-pixels in the continuous γ-row are driven in the bright area and the sub-pixels in the other consecutive γ-row are driven in the dark area, so that the sub-pixels in the bright-area driven γ-row and the sub-pixels in the dark-area driven γ-row are offset. Based on this, the difference between light and dark or the phenomenon of interlacing between light and dark is eliminated, so as to solve the problem of flickering and graininess in the display of the display panel, and improve the display quality of the display panel.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a driving method of a display panel and a display device. Background technique [0002] Currently, liquid crystal display panels generally adopt VA (Vertical Alignment negative vertical alignment) liquid crystal technology or APS (In Panel Switching coplanar switching) liquid crystal technology. Among them, the VA-type liquid crystal technology has the advantages of higher production efficiency and lower manufacturing cost compared with the APS-type liquid crystal technology. In the VA-type liquid crystal technology, the wide viewing angle technology is generally used to improve the display viewing angle of the VA-type liquid crystal display panel. [0003] In the non-wide viewing angle technology, the large viewing angle gamma curve corresponding to each sub-pixel is relatively large. In the wide viewing angle technology, a sub-pixel is divided into a bright are...
