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.
