Abstract: The present disclosure provides a method for driving a display panel, a display panel, and a display device, which relates to the technical field of liquid crystal display technologies, and can decrease a risk of abnormal display caused by a sudden change of voltage on a touch electrode, when finishing a touch stage and entering into a display stage. The method includes:when finishing a touch stage and entering into a display stage, compensating a charging voltage value corresponding to first N rows of to-be-charged pixel electrodes in the display stage; and charging the first N rows of the to-be-charged pixel electrodes according to a charging voltage value after compensation; wherein N is an integer greater than or equal to 1. The technical solution is mainly used in a charging process of the pixel electrodes.

Abstract: A touch-control display panel, a driving method thereof, and a touch-control display device are provided. The display panel includes a first substrate and a plurality of touch-control driving electrodes extending along a second direction. The first substrate includes a first touch-control display region and a second touch-control display region arranged along a first direction. The plurality of touch-control driving electrodes include first touch-control driving electrodes distributed in the first touch-control display region and second touch-control driving electrodes distributed in the second touch-control display region. The number of the first touch-control driving electrodes is equal to the number of the second touch-control driving electrodes. One first touch-control driving electrode and one second touch-control driving electrode are scanned simultaneously, a distance from the one first touch-control driving electrode to the second touch-control display region is equal to a distance from the one second touch-control driving electrode to the first touch-control display region.
