    摘要： A compensation method of a display panel includes controlling a first display part of a target panel to display a light load image based on a standard gamma curve, controlling a second display part of the target panel to display a heavy load image, acquiring a first brightness of a first color sub-pixels in an (N1+1)th row electrically connected to a first data line of the first display part, acquiring a second brightness of the first color sub-pixels in an (N2+1)th row of a first sub-display part of the second display part electrically connected to a second data line, and according to a difference between the first brightness and the second brightness, determining a first compensation data corresponding to the first gray scale and the second preset gray scale of at least the first color sub-pixels of the first sub-display part in the target panel.

    摘要： A backlight driving method is provided. The method includes: determining a first duration of a first active pulse phase in a backlight driving signal corresponding to a target frame of a to-be displayed picture in a display panel, based on a target duty ratio and a first period corresponding to a target previous frame; wherein the target previous frame is a frame preceding the target frame, and the backlight driving signal is configured to drive a backlight of the display panel; and determining a second duration based on a maximum period corresponding to a frame at a lowest refresh frequency of the display panel and the first period, to delay a start time of the first active pulse phase based on the second duration.
