1. A method for driving a display panel, the display panel comprising a plurality of data lines and a plurality of sub-pixels electrically connected to the plurality of data lines; the plurality of the sub-pixels including a plurality of first sub-pixels, a plurality of second sub-pixels, and a plurality of third sub-pixels, the plurality of sub-pixels being arranged in intersecting row and column directions to form a plurality of sub-pixel rows arranged in the column direction, and to form a plurality of sub-pixel columns arranged in the row direction, the plurality of sub-pixel rows including a plurality of first sub-pixel rows, a plurality of second sub-pixel rows, and a plurality of third sub-pixel rows that are alternately arranged, display colors of a plurality of the sub-pixels in a same one of the sub-pixel rows being the same, display colors of the sub-pixels in the first sub-pixel row, display colors of the sub-pixels in the second sub-pixel row, and display colors of the sub-pixels in the third sub-pixel row being different; the method comprising:
driving a plurality of the sub-pixels to display in a plurality of frames, wherein each of the sub-pixels has one of a high grayscale data compensation state and a low grayscale data compensation state and has one of a positive polarity and a negative polarity in each of the frames;
wherein each of the sub-pixel columns includes a plurality of sub-pixel groups including a first sub-pixel group, a third sub-pixel group, and a second sub-pixel group located between the first sub-pixel group and the third sub-pixel group, the first sub-pixel group and the third sub-pixel group being connected to a corresponding one of the data lines, the second sub-pixel group being connected to another adjacent one of the data lines and including 2n sub-pixels of the plurality of sub-pixels, with n being an integer greater than or equal to 0;
wherein in a same frame, among a plurality of the sub-pixels, in any two adjacent ones of the sub-pixel columns, whose display colors are the same and have the high grayscale data compensation state, at least one of the sub-pixels has a polarity different from that of other ones of the sub-pixels.
