Summary:A touch device according to one embodiment comprises: a touch panel including a plurality of touch electrodes; a driving/receiving unit for applying a first driving signal to the touch panel while driving in a first mode, and applying, to the touch panel, a second driving signal that differs from the first driving signal while driving in a second mode; and a control unit which obtains first touch data by comparing a first threshold and first detection signals received from the touch panel while driving in the first mode, and which obtains second touch data by comparing a second threshold and second detection signals received from the touch panel while driving in the second mode, wherein the control unit can determine the second threshold on the basis of at least some of the first detection signals. Selon un mode de réalisation, l'invention concerne un dispositif tactile comprenant : un panneau tactile comportant une pluralité d'électrodes tactiles ; une unité d'entraînement/réception permettant d'appliquer un premier signal d'entraînement au panneau tactile lors de l'entraînement dans un premier mode, et d'appliquer, au panneau tactile, un second signal d'entraînement, différent du premier signal d'entraînement, lors de l'entraînement dans un second mode ; et une unité de commande destinée à obtenir des premières données tactiles au moyen de la comparaison entre un premier seuil et des premiers signaux de détection reçus en provenance du panneau tactile lors de l'entraînement dans le premier mode, et destinée à obtenir des secondes données tactiles au moyen de la comparaison entre un deuxième seuil et des seconds signaux de détection reçus en provenance du panneau tactile lors de l'entraînement dans le second mode, l'unité de commande pouvant déterminer le deuxième seuil en fonction d'au moins certains signaux parmi les premiers signaux de détection. 일 실시 예에 따른 터치 장치는 복수의 터치 전극을 포함하는 터치 패널, 제1 모드로 구동하는 동안 제1 구동 신호를 상기 터치 패널로 인가하고, 제2 모드로 구동하는 동안 상기 제1 구동 신호와 다른 제2 구동 신호를 상기 터치 패널로 인가하는 구동/수신부, 및 상기 제1 모드로 구동하는 동안 상기 터치 패널로부터 수신되는 제1 감지 신호들과 제1 임계치를 비교하여 제1 터치 데이터를 획득하고, 상기 제2 모드로 구동하는 동안 상기 터치 패널로부터 수신되는 제2 감지 신호들과 제2 임계치를 비교하여 제2 터치 데이터를 획득하는 제어부를 포함하고, 상기 제어부는, 상기 제1 감지 신호들 중 적어도 일부에 기초하여 상기 제2 임계치를 결정할 수 있다.
