Abstract
The present disclosure is related to a display driving method. The display driving method may include obtaining a grayscale data voltage compensation table; calculating a value of VCOM shift amplitude corresponding to a row of sub-pixels on a display panel based on grayscale data voltages of a frame of an image to be displayed; obtaining a grayscale data voltage compensation value corresponding to the row of sub-pixels on the display panel based on the calculated value of VCOM shift amplitude and the grayscale data voltage compensation table; compensating grayscale data voltages actually inputted to the row of sub-pixels based on the grayscale data voltage compensation value to obtain compensated grayscale data voltages; and outputting the compensated grayscale data voltages to the row of sub-pixels during a display time of the frame of the image to be displayed.
