Touch display apparatus, driving circuit, and driving method

A touch display apparatus, a corresponding driving circuit, and a driving method. The touch display apparatus comprises a common electrode (105) and a driving circuit (100). The common electrode (105) is disposed between a first substrate and a second substrate (111), and is used as a touch sensing electrode during a touch sensing phase. The driving circuit (100) is used for providing a first signal for touch detection to the common electrode (105); the driving circuit (100) is also used for providing a second signal to a gate line during the touch sensing phase, said second signal enabling a thin-film transistor (104) to be in off mode and decreasing the charge-discharge capacity of a capacitor formed by the common electrode (105) and a gate line; and/or, the driving circuit (100) is also used for providing a third signal during the touch sensing phase, and the third signal can decrease the charge-discharge capacity of a capacitor formed by the common electrode (105) and a data line. The touch display apparatus, the corresponding driving circuit and the driving method can reduce interference of a parasitic capacitor to touch detection, thereby improving the touch detection precision.
