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.

摘要： The present application provides a display panel control method and a display module. A display voltage corresponding to corresponding pixel unit can be compensated for based on a difference between a first feed-through voltage generated by a pixel electrode when a first transistor is turned from on to off and a second feed-through voltage generated by a common electrode when a second transistor is turned from on to off, so as to improve the problem such as the flicker or the image sticking in the display picture due to the unevenness of the feed-through voltages.
