Abstract

The invention discloses a driving method of a display panel, a driving device of the display panel and a display device. The display device comprises a display panel and a driving device of the display panel, the display panel is divided into a plurality of array areas, wherein each array area comprises a plurality of pixel columns, and each pixel column is provided with a corresponding common electrode. The polarity of the common electrode of the pixel column in each array area is detected; the number of the pixel columns with the arrangement mode of the polarity of the common electrodes in asingle array area meeting a preset arrangement relation is obtained; when the number is larger than or equal to a preset number, a driving signal of the array area where the pixel columns are locatedis reversed in a preset manner and then is loaded into the array area, so that the polarity distribution of the common electrodes of the pixel columns is balanced, the display of a green pixel columnis influenced, and the problem that the picture is greenish is solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel driving method, a driving device thereof, and a display device. Background technique [0002] An array substrate of an existing display device, the array substrate includes three pixel columns repeatedly arranged, the three pixel columns are respectively a red pixel column, a green pixel column and a blue pixel column, and each pixel column corresponds to a common electrode, Adjacent common electrodes have opposite polarities, and each pixel column drives its corresponding common electrodes with an independent common voltage. In the picture displayed on the array substrate, there is an alternating bright and dark picture. In the bright pixel row, the polarities of the common electrodes corresponding to the red pixel row and the blue pixel row are positive, and the polarities of the common electrodes corresponding to the green pixel row are positive. The ...
