1. A driving method of a display device, the display device comprising a plurality of scan lines, a plurality of a data lines, and a plurality of LED lights driven by the plurality of scan lines and the plurality of data lines; wherein the plurality of LED lights are arranged in a plurality of rows and a plurality of columns; wherein an anode of each LED is connected to the respective scan line, and a cathode of each LED is connected to the respective data line; wherein the driving method comprises:
obtaining a compensated display grayscale corresponding to an LED in an instant row based on a display grayscale of an LED in a previous row, a display grayscale of the LED in the instant row, and a display grayscale compensation table;
obtaining corresponding driving parameters according to the compensated display grayscale corresponding to the LED in the instant row; and
controlling the LED in the instant row to display according to the driving parameters;
wherein the obtaining the compensated display grayscale corresponding to the LED in the instant row based on the display grayscale of the LED in the previous row, the display grayscale of the LED in the instant row, and the display grayscale compensation table comprises:
calculating a parasitic capacitance on the respective data line corresponding to the LED in the previous row based on the display grayscale of the LED in the previous row;
calculating a respective compensation value for the display grayscale of the LED in the instant row based on the parasitic capacitance obtained by the LED in the previous row and the display grayscale of the LED in the instant row; and
obtaining the compensated display grayscale corresponding to the LED in the instant row based on the compensation value so as to generate the display grayscale compensation table.
