Abstract

A display panel and a driving method thereof are provided. The display panel includes a plurality of subpixels and a plurality of data lines. The plurality of subpixels are divided into a plurality of unit regions. Two sides of any column of the subpixels correspond to two of the data lines with different polarities respectively. The polarities of the subpixels of any column are same. The unit regions include a plurality of unit subregions. Grayscales of the subpixels in each unit subregion are same, and grayscales of the subpixels in two adjacent unit subregions are different.
