Abstract: 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.
