Zusammenfassung:	Embodiments of the present invention relate to a touch display device, a touch driving circuit, and a touch driving method and, more particularly, to a touch display device, a touch driving circuit, and a touch driving method capable of improving a resolution for determination of multitouch by varying amplification gain of a touch sensing signal according to a distance between a touch peak values of adjacent touch sensing signals. 본 발명의 실시예들은 터치 디스플레이 장치, 터치 구동 회로 및 터치 구동 방법에 관한 것으로서, 더욱 상세하게는, 인접한 터치 센싱 신호의 터치 피크값 사이의 거리에 따라 터치 센싱 신호의 증폭 이득을 달리함으로써, 멀티 터치의 판단에 대한 분해능을 개선할 수 있는 터치 디스플레이 장치, 터치 구동 회로 및 터치 구동 방법에 관한 것이다.
