Claim 2:
3. The display panel driving method according to claim 2, wherein before the calculating, based on target grayscale values of a first pixel unit row in the picture data of the frame to be displayed, a proportion of low gray scale pixel units in the first pixel unit row, the display panel driving method further comprises:
calculating, based on target grayscale values of the first pixel unit row to an nth pixel unit row in the picture data of the frame to be displayed, a proportion of low grayscale pixel units in the first pixel unit row to the nth pixel unit row, wherein n is an integer greater than 1; and
determining whether the proportion of the low grayscale pixel units in the first pixel unit row to the nth pixel unit row is less than or equal to a second preset proportion threshold; and
the calculating, based on target grayscale values of a first pixel unit row in the picture data of the frame to be displayed, a proportion of low grayscale pixel units in the first pixel unit row comprises:
if the proportion of the low grayscale pixel units in the first pixel unit row to the nth pixel unit row is less than or equal to the second preset proportion threshold, calculating, based on the target grayscale values of the first pixel unit row in the picture data of the frame to be displayed, the proportion of the low grayscale pixel units in the first pixel unit row.
