Abstract
A touch display apparatus, a corresponding driving circuit, and a driving method are provided. The touch display apparatus includes a driving circuit configured to, during the touch sensing stage, provide a first signal to a common electrode for realizing touch detection during the touch sensing stage, a second signal used to control a thin film transistor of the touch display apparatus to be switched off and is used to decrease charge and discharge capacity of a capacitor formed by the common electrode and the gate line, and a third signal used to decrease charge and discharge capacity of a capacitor formed by the common electrode and a data line. The third signal is used to control the data line to enter a floating state during the touch sensing stage.
