Display panel driving method for adjusting sub-pixel row scanning duration based on image data, driving circuit, and display apparatus

A driving circuit, wherein the driving circuit is configured to drive a display panel to display, and the display panel comprises n scan lines extending in a row direction and n sub-pixel rows in one-to-one correspondence with the n scan lines, wherein n is an integer greater than 1 the driving circuit comprising:

• a timing controller;
• and a scan driving circuit,
• wherein the timing controller is configured to:
• acquire image data of an image to be displayed;
• determine a necessary charging duration of each sub-pixel row according to the image data;
• and
• control, the scan driving circuit to control the n scan lines according to a preset sequence to sequentially scan the n sub-pixel rows, to drive the display panel to display the image to be displayed, wherein a scanning duration of each scan line is positively correlated to the necessary charging duration of a sub-pixel row corresponding to the scan line, and
• wherein the timing controller configured to determine the necessary charging duration of each sub-pixel row according to the image data is configured to:
• determine a target grayscale of each sub-pixel according to the image data:
• determine a sub-pixel with a highest target grayscale in each sub-pixel row as a target sub-pixel of the sub-pixel row:
• determine a shortest charging duration of each target sub-pixel according to the target grayscale of each target sub-pixel;
• and
• determine the shortest charging duration of each target sub-pixel as the necessary charging duration of a sub-pixel row where the target sub-pixel is located.
