Claim 10:
11. The drive circuit according to claim 10, wherein the algorithm controller is further configured to:
calculate, 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
determine 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 algorithm controller configured to calculate, based on target grayscale values of the first pixel unit row in the picture data of the frame to be displayed, the proportion of low grayscale pixel units in the first pixel unit row is configured to:
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, calculate, 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.
