| Zusammenfassung: | The present embodiment may provide a touch circuit comprising: a touch driving circuit that supplies a touch driving signal to touch electrodes; a touch sensing circuit that senses a capacitance change of a touch electrode through a touch sensing line; and a multiplexer connected to the touch sensing line to transfer the capacitance change of the touch electrode to the touch sensing circuit. Some of the touch electrodes of the touch circuit is selectively short-circuited according to a driving mode of the touch circuit, a node of the touch electrode is connected so that the touch electrodes are electrically connected to the other touch electrodes. Therefore, the present invention can reduce a power usage amount consumed on a touch panel.
본 실시예는 터치구동신호를 터치전극에 공급하는 터치구동회로, 터치전극의 정전용량 변화를 터치센싱라인을 통해 센싱하는 터치센싱회로; 및 터치센싱라인과 연결되어 상기 터치전극의 정전용량 변화를 상기 터치센싱회로로 전달하는 멀티플렉서를 포함하는 터치회로를 제공할 수 있다. 터치회로의 터치전극 중 일부는 터치회로의 구동모드에 따라 선택적으로 단락되고, 터치전극의 노드가 연결되어 다른 터치전극과 전기적으로 연결될 수 있다. |
