Zusammenfassung:Disclosed are a capacitance-type touch panel device and an operation method for same. In order that the effect of disturbance noise comprised in a reception signal is minimized, a calculation for a digital code which has been converted into a digital signal type is performed. Information about the noise level of the digital code is compared to a reference value, and, if the frequency of the noise is determined to be similar to the frequency of the reception signal, the frequency of an operation signal, which is supplied from a signal generation unit, is changed. L'invention concerne un dispositif d'écran tactile de type capacitif et un procédé de fonctionnement de celui-ci. Afin de minimaliser l'effet de bruit parasite compris dans un signal de réception, un calcul associé à un code numérique ayant été converti en un type de signal numérique est effectué. Des informations relatives au niveau de bruit du code numérique sont comparées à une valeur de référence, et s'il est déterminé que la fréquence du bruit est similaire à la fréquence du signal de réception, la fréquence d'un signal de fonctionnement fourni par une unité de génération de signal est modifiée. 정전용량형 터치 패널 장치 및 이의 구동방법이 개시된다. 수신 신호에 포함된 외란 노이즈의 영향을 최소화하기 위해 디지털 신호의 형태로 변환된 디지털 코드에 대한 연산이 수행된다. 디지털 코드의 노이즈레벨에 대한 정보는 기준값과 비교되고, 노이즈가 가지는 주파수가 수신 신호의 주파수와 유사하다고 판단되는 경우, 신호 생성부에서 공급되는 구동 신호의 주파수는 변경된다.
