Claim 0:
1. A display panel driving method, wherein the display panel driving method is used 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, 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, and each scanning line is used to output a corresponding scanning signal to a corresponding pixel unit row, wherein
the display panel driving method comprises:
obtaining a target grayscale value of each pixel unit in picture data of a frame to be displayed;
determining, 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
when the display panel is driven to display a picture of the frame to be displayed, outputting 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, which comprises: when a non-target pixel unit row is scanned, outputting, 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 a target pixel unit row is scanned, outputting, 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.
