Zusammenfassung:	A touch display driving integrated circuit according to an embodiment of the present invention includes a touch driving circuit connected to touch electrodes through touch sensing lines, respectively, and a source driving circuit connected to pixels through the data lines. The touch driving circuit provides a sensing signal to first touch sensing lines of the touch sensing lines in a touch section, applies a common voltage to second touch sensing lines of the touch sensing lines in a display section, and applies a voltage different from the common voltage to third touch sensing lines different from the second touch sensing lines. Accordingly, the present invention can improve reliability and performance. 본 발명의 실시 예에 따른 터치 디스플레이 구동 집적 회로는 터치 감지 라인들을 통해 터치 전극들과 각각 연결되도록 구성되는 터치 구동 회로, 및 데이터 라인들을 통해 픽셀들과 연결되도록 구성되는 소스 구동 회로를 포함한다. 터치 구동 회로는, 터치 구간에서, 터치 감지 라인들 중 제1 터치 감지 라인들로 감지 신호를 제공하고, 표시 구간에서, 터치 감지 라인들 중 제2 터치 감지 라인들로 공통 전압을 인가하고, 제2 터치 감지 라인들과 다른 제3 터치 감지 라인들로 공통 전압과 다른 전압을 인가한다.
