Abstract

A driving circuit configured to drive a touch display panel is provided. The driving circuit includes a signal generating circuit and a sensor driving circuit. The signal generating circuit is configurable to be coupled to gate lines of the touch display panel via a gate control circuit. The signal generating circuit modulates a plurality of voltage signals on a first driving signal and a second driving signal, and provides the modulated first driving signal and the modulated second driving signal to the gate control circuit to drive the gate lines during a sensing period. The sensor driving circuit is configurable to be coupled to sensor pads of the touch display panel. The sensor driving circuit modulates the voltage signals on a third driving signal, and drives the sensor pads with the modulated third driving signal during the sensing period. A method for driving a touch display panel is also provided.
