Summary:A touchscreen panel according to the embodiments of the present invention comprises: a touch detection part comprising a plurality of driving electrodes and a plurality of sensing electrodes insulated and crossing the driving electrodes; and a driving signal generating part that provides a driving signal to the driving electrodes. The driving signal generating part comprises touch drivers disposed between a digital-to-analog converter providing a first signal or a second signal and the driving electrodes, and each of the touch drivers is connected to a preset number of driving electrodes among the driving electrodes. Therefore, the present invention is capable of reducing the number of touch drivers. 본 발명의 실시예들에 따른 터치 스크린 패널은, 복수의 구동 전극들 및 구동 전극들과 절연되어 교차하는 복수의 센싱 전극들을 포함하는 터치 감지부, 구동 전극들에 구동 신호를 제공하는 구동 신호 생성부를 포함한다. 구동 신호 생성부는, 제1 신호 또는 제2 신호를 제공하는 디지털 아날로그 컨버터와 구동 전극들 사이에 배치되는 터치 드라이버들을 포함하고, 터치 드라이버들 각각은, 구동 전극들 중 기 설정된 개수의 구동전극들과 연결된다.
