Abstract:
The present disclosure discloses a touch display panel, a display apparatus, and a method for driving the touch display panel. The touch display panel includes an upper substrate; a lower substrate disposed opposite to the upper substrate; a plurality of pixels located between the upper substrate and the lower substrate and arranged in a matrix; a driving chip configured to scan a plurality of pixels progressively; and a common electrode layer located between the upper substrate and the lower substrate and divided into a plurality of self-capacitance electrodes which are independent of each other, wherein the self-capacitance electrodes are connected to the driving chip through corresponding wires, wherein the driving chip is further configured to apply a common electrode signal to each row of self-capacitance electrodes only when pixels corresponding to the corresponding row of self-capacitance electrodes are in a scanning state.
