Abstract: The present invention provides a touch display driving circuit, which comprises a source driving circuit and a touch detection circuit. The source driving circuit is coupled to a plurality of source lines of a touch display panel. The touch display driving circuit outputs a touch driving signal to one of the plurality of source lines during a touch detection cycle. The touch detection circuit receives a plurality of touch sensing signals via the corresponding common electrode of the source line. The plurality of touch sensing signals are then generated according to the touch driving signal.
