摘要： A touch control module, a display panel, a display device, and a touch control method. The touch control module includes a first substrate and an array of touch electrodes disposed on a first surface of the first substrate. In a touch control period of a touch electrode row, the touch electrode row and at least one touch electrode row directly adjacent to the touch electrode row are configured to receive a same touch scan signal simultaneously. Therefore, under synchronous modulation, the influence of the coupling between directly adjacent touch electrode rows is reduced and overall uniformity of the capacitance is achieved, so that accuracy of the touch positioning and the pressure touch control can be improved.
