1. A driving method of an array substrate, wherein the array substrate comprises:
a plurality of sub-pixels arranged in an array and divided into a plurality of pixel groups according to two adjacent columns of sub-pixels as a group, each pixel group comprising first sub-pixels and second sub-pixels provided in turn;
each of a plurality of data drive signal lines provided between two columns of sub-pixels of each pixel group and electrically connected to each sub-pixel of the pixel group;
a plurality of first row scan drive signal lines;
a plurality of second row scan drive signal lines;
in a same row, a first sub-pixel of each pixel group being connected to a first row scan drive signal line and a second sub-pixel of each pixel group being connected to a second row scan drive signal line, each column of sub-pixels being composed of first sub-pixels or second sub-pixels;
wherein the driving method of the array substrate comprises:
controlling the plurality of data drive signal lines to output a first polarity data drive signal in a first time period and output a second polarity data drive signal in a second time period alternately;
outputting the first polarity data drive signal to drive the first sub-pixels of each pixel group to make the first sub-pixels of each pixel group to be a first polarity in the first time period; and
outputting the second polarity data drive signal to drive the second sub-pixels of each pixel group to make the second sub-pixels of each pixel group to be a second polarity in the second time period, wherein polarities of sub-pixels of each column of sub-pixels are same.
