a plurality of gate lines, wherein the plurality of gate lines are sequentially scanned during an active period in a frame period, and the plurality of gate lines are maintained at a low level voltage during a blank period in the frame period; and

a plurality of data lines, comprising a first data line, wherein voltage polarities of the plurality of data lines for all the blank period are respectively identical with voltage polarities of the plurality of data lines during the active period, a first level voltage is applied to the first data line during all the blank period, the first level voltage is related to an average value or a maximum value of level voltages of all of the plurality of data lines during the active period, a time length of the blank period is longer than a first time length of a first blank period, and a first frame period comprising the first blank period is adjacent to the frame period.
