Title (EN) METHOD AND APPARATUS FOR SENSING A PLURALITY OF CONTACT INPUTS
(FR) MÉTHODE ET APPAREIL DE DÉTECTION D'UNE PLURALITÉ D'ENTRÉES PAR CONTACT
(KO) 복수의 접촉 입력을 감지하는 방법 및 장치
Abstract:
(EN) The present invention relates to a method for sensing contact inputs in a contact input sensing apparatus comprising a sensing electrode. The method for sensing contact inputs comprises: a first step of enabling an input terminal of the sensing electrode to supply a driving signal for a first time period so as to obtain a sensed signal; a second step of enabling the input terminal of the sensing electrode to supply a driving signal for a second time period so as to obtain a sensed signal; and a third step of determining the location of the contact input based on the difference between the sensed signal obtained in the first step and the sensed signal obtained in the second step, wherein the first time period and the second time period are different from each other. The coordinates of the contact inputs can thereby be accurately determined even when two or more contact inputs are applied.
(FR) L'invention concerne une méthode de détection d'entrées par contact dans un appareil de détection d'entrée par contact comprenant une électrode de détection. La méthode de détection d'entrées par contact comprend : une première étape d'activation d'une borne d'entrée de l'électrode de détection afin qu'un signal d'excitation soit fourni pendant une première période, de manière qu'un signal détecté soit obtenu; une deuxième étape d'activation de la borne d'entrée de l'électrode de détection afin qu'un signal d'excitation soit fourni pendant une deuxième période, de manière qu'un signal détecté soit obtenu; et une troisième étape de détermination de l'emplacement de l'entrée par contact en fonction de la différence entre le signal détecté obtenu dans la première étape et le signal détecté obtenu dans la deuxième étape, la première et la deuxième période étant différentes. Les coordonnées des entrées par contact peuvent ainsi être déterminées avec précision même lorsque deux entrées par contact ou plus sont appliquées.
(KO) 감지 전극을 포함하는 접촉 입력 감지 장치에서 접촉 입력을 감지하는 방법이 개시된다. 접촉 입력 감지 방법은 제1시간 동안 상기 감지 전극의 입력단에서 구동 신호를 공급하고 감지 신호를 산출하는 제1단계와, 제2시간 동안 상기 감지 전극의 상기 입력단에서 구동 신호를 공급하고 감지 신호를 산출하는 제2단계와, 상기 제1단계에서 산출된 감지 신호와 상기 제2단계에서 산출된 감지 신호의 차이에 기초하여 접촉 입력의 위치를 결정하는 제3단계를 포함하되, 상기 제1시간과 상기 제2시간은 서로 다른, 접촉 입력 감지 방법이 제공된다. 이로써, 2 이상의 접촉 입력이 인가된 경우에도 접촉 입력의 좌표를 정확하게 결정할 수 있다.
