Abstract: Provided are a display panel, a driving method thereof and a display device, for improving the quality of displayed images and reducing the power consumption. The display panel includes first and second pixel units of opposite polarities, and first and second data lines for transmitting signals of opposite polarities. The first and the second pixel units each includes at least two sub-pixels of different colors. The first data line is connected to the first pixel units in the (j−1)th and jth columns of sub-pixels. Sub-pixels in the first pixel unit in the (j−1)th column have different colors from those in the first pixel unit in the jth column. The second data line is connected to the second pixel units in the jth and (j+1)th columns. Sub-pixels in the second pixel unit in the jth column have different colors from those in the second pixel unit in the (j+1)th column.

Abstract: An array substrate includes a substrate; scan lines and data lines arranged on the substrate and intersecting one another to define sub-pixels, each of which includes a pixel electrode including strip-like electrodes whose long axes of a same row are parallel to one another. Extension lines of long axes of strip-like electrodes in sub-pixels in any two adjacent rows intersect one another. The touch electrode is electrically connected to at least one touch signal line. Each touch signal line includes straight-line portions and fold-line portions. Two adjacent straight-line portions are connected by one fold-line portion. Any straight-line portion is parallel to long axes of strip-like electrodes in sub-pixels in a same row. Extension lines of fold-line portions intersect long axes of strip-like electrodes. Orthographic projections of fold-line portions on the substrate overlap orthographic projections of scan lines on the substrate. Fold-line portions are not perpendicular to scan lines.
