Touch detection circuit, its driving method and display device
The present disclosure provides a touch detection circuit, its driving method and a display device. The touch detection circuit includes a touch sensing electrode, a switch control unit, a touch detection unit, a first control signal terminal, a second control signal terminal, a third control signal terminal, a fourth control signal terminal, and a signal output terminal. At a charging stage subsequent to an initialization stage, a touch capacitance is generated at a position corresponding to the touch sensing electrode in the case that the touch sensing electrode is being touched, and the touch sensing electrode is charged through the switch control unit under the control of the first control signal terminal. As a result, it is able to detect charges stored on the touch sensing electrode by the touch detection unit at a detection stage, thereby to determine whether or not the touch sensing electrode is being touched in accordance with a detection signal from the signal output terminal.
