Claim 9:
10. The drive circuit according to claim 9, wherein the algorithm controller configured to determine, based on the target grayscale value of the pixel unit in the picture data of the frame to be displayed, the target pixel unit row that needs luminance compensation in the frame to be displayed is configured to:
calculate, 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, wherein the low grayscale pixel unit is a pixel unit with a target grayscale value less than a preset low grayscale threshold;
determine whether the proportion of the low grayscale pixel units in the first pixel unit row is greater than or equal to a first preset proportion threshold;
if the proportion of the low grayscale pixel units in the first pixel unit row is greater than or equal to the first preset proportion threshold, determine that the first pixel unit row is a target pixel unit row; and
if the proportion of the low grayscale pixel units in the first pixel unit row is less than the first preset proportion threshold, determine that the first pixel unit row is not a target pixel unit row.
