Abstract:
The present disclosure provides a touch display panel and a driving method therefor, and a display device including the touch display panel, relating to the field of display technologies, and enabling a touch function of the display panel without increasing the thickness of the display panel. The touch display panel includes an upper substrate and a lower substrate, a plurality of gate lines and a plurality of data lines provided on the lower substrate and defining a plurality of sub-pixel regions, in each of which at least one common electrode block is provided, at least one common electrode block is configured to also function as a touch driving electrode; the touch display panel further comprises a touch sensing chip and a touch sensing electrode, the touch driving electrode and the touch sensing electrode being respectively electrically connected to output ends of the touch sensing chip; the touch sensing chip is configured to, during a touch time period, apply a touch driving signal to the touch driving electrode, apply a touch sensing signal to the touch sensing electrode, and detect a change of the touch sensing signal on the touch sensing electrode so as to determine a touch position on the touch display panel.
