Summary:A touch detection apparatus according to an embodiment comprises: a touch panel which includes a plurality of first touch electrodes extending in a first direction and arranged in a second direction crossing the first direction, and a plurality of second touch electrodes extending in the second direction and arranged in the first direction; and a touch driving unit which, in a first section, applies first driving signals to the touch panel so as to generate a resonance signal of a stylus pen, and which, in a second section following the first section, receives detection signals from all of the plurality of first touch electrodes and the plurality of second touch electrodes. L'invention porte, selon un mode de réalisation, sur un appareil de détection tactile qui comprend : un panneau tactile qui comprend une pluralité de premières électrodes tactiles s'étendant dans une première direction et agencées dans une seconde direction croisant la première direction, et une pluralité de secondes électrodes tactiles s'étendant dans la seconde direction et agencées dans la première direction ; et une unité d'entraînement de toucher qui, dans une première section, applique des premiers signaux d'attaque au panneau tactile de sorte à générer un signal de résonance d'un stylet, et qui, dans une seconde section après la première section, reçoit des signaux de détection en provenance de la totalité de la pluralité de premières électrodes tactiles et de la pluralité de secondes électrodes tactiles. 일 실시예에 따른 터치 장치는 제1 방향으로 연장되고, 제1 방향과 교차하는 제2 방향으로 배열되는 복수의 제1 터치 전극, 제2 방향으로 연장되고, 제1 방향으로 배열되는 복수의 제2 터치 전극을 포함하는 터치 패널, 그리고 제1 구간에 스타일러스 펜의 공진 신호 발생을 위한 제1 구동 신호를 터치 패널에 인가하고, 제1 구간 다음의 제2 구간에 복수의 제1 터치 전극과 복수의 제2 터치 전극 모두로부터 감지 신호를 수신하는 터치 구동부를 포함한다.
