Abstract
A driving circuit capable of enabling a display structure to provide a touch function, including: a first multiplexing interface for coupling with multiple gate driving lines; a second multiplexing interface for coupling with at least one storage capacitor driving line; a third multiplexing interface for coupling with multiple source driving lines; a fourth multiplexing interface for coupling with multiple transparent electrodes; and a control unit for driving the gate driving lines via the first multiplexing interface to form a capacitive network on a TFT display structure, and performing a capacitive touch detection procedure on the capacitive network via an interface selected from a group consisting of the second multiplexing interface, the third multiplexing interface, the fourth multiplexing interface, and any combination thereof.
