Claim 8:
9. A drive circuit, wherein the drive circuit is configured to drive a display panel for displaying, the display panel comprises a plurality of scanning lines extending along a row direction, a plurality of data lines extending along a column direction, and a plurality of pixel units arranged in an array and defined by intersections of the plurality of scanning lines and the plurality of data lines, wherein
the drive circuit comprises a row driver, an algorithm controller, and a timing controller separately electrically connected to the row driver and the algorithm controller, wherein the timing controller is configured to control the row driver to output corresponding scanning signals to corresponding pixel unit rows through scanning lines;
the algorithm controller is configured to obtain a target grayscale value of each pixel unit in picture data of a frame to be displayed, determine, based on the target grayscale value of the pixel unit in the picture data of the frame to be displayed, a target pixel unit row that needs luminance compensation in the frame to be displayed, and feed the target pixel unit row back to the timing controller; and
in a process of the display panel displaying a picture of the frame to be displayed, the timing controller is configured to control the row driver to output corresponding scanning signals through the plurality of scanning lines according to a preset time sequence to implement progressive scanning of a plurality of pixel unit rows, wherein when the drive circuit scans a non-target pixel unit row, the timing controller is specifically configured to control the row driver to output, through scanning lines corresponding to the non-target pixel unit row, scanning signals with turn-on voltages each equal to a first turn-on voltage; and when the drive circuit scans a target pixel unit row, the timing controller is specifically configured to control the row driver to output, through scanning lines corresponding to the target pixel unit row, scanning signals with turn-on voltages higher than the first turn-on voltage, wherein the non-target pixel unit row is a pixel unit row other than the target pixel unit row.
