Patent attributes
A touch display apparatus, a corresponding driving circuit, and a driving method. The touch display apparatus includes a common electrode between a first substrate and a second substrate, and a driving circuit used as a touch sensing electrode during a touch sensing phase. The driving circuit is used for providing a first signal for touch detection to the common electrode. The driving circuit 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 to be in off mode and decreasing the charge-discharge capacity of a capacitor formed by the common electrode and a gate line. The driving circuit is also used for providing a third signal during the touch sensing phase, the third signal decreasing the charge-discharge capacity of a capacitor formed by the common electrode and a data line.
