Abstract: front page image
(EN)Disclosed is a touch input device comprising: a touch electrode pad disposed so as to generate a touch input capacitance between a user input tool and the touch electrode pad; a first switch and a first operational amplifier; and a second switch and a second operational amplifier. A first one end of the first switch is connected to the touch electrode pad and a first other end of the first switch is connected to a non-inverting input terminal of the first operational amplifier; a second one end of the second switch is connected to the touch electrode pad and a second other end of the second switch is connected to a non-inverting input terminal of the second operational amplifier; a first potential (VH) is applied to an inverting input terminal of the first operational amplifier and a second potential (VL) is applied to an inverting input terminal of the second operational amplifier (wherein the second potential < the first potential); a first integrated capacitor is connected between the non-inverting input terminal of the first operational amplifier and an output terminal of the first operational amplifier; and a second integrated capacitor is connected between the non-inverting input terminal of the second operational amplifier and an output terminal of the second operational amplifier.
(FR)La présente invention concerne un dispositif d'entrée tactile comprenant : une électrode tactile disposée de sorte à générer une capacitance d'entrée tactile entre un outil d'entrée utilisateur et l'électrode tactile ; un premier commutateur et un premier amplificateur opérationnel ; et un second commutateur et un second amplificateur opérationnel. Une première extrémité du premier commutateur est connectée à l'électrode tactile et l'autre première extrémité du premier commutateur est connectée à une borne d'entrée non inversée du premier amplificateur opérationnel ; une seconde extrémité du second commutateur est connectée à l'électrode tactile et l'autre seconde extrémité du second commutateur est connectée à une borne d'entrée non inversée du second amplificateur opérationnel ; un premier potentiel (VH) est appliqué à une borne d'entrée inversée du premier amplificateur opérationnel et un second potentiel (VL) est appliqué à une borne d'entrée inversée du second amplificateur opérationnel, le second potentiel étant inférieur au premier potentiel ; un premier condensateur d'intégration est connecté entre la borne d'entrée non inversée du premier amplificateur opérationnel et une borne de sortie du premier amplificateur opérationnel ; et un second condensateur d'intégration est connecté entre la borne d'entrée non inversée du second amplificateur opérationnel et une borne de sortie du second amplificateur opérationnel.
(KO)사용자 입력도구와의 사이에서 터치입력 커패시턴스를 발생시키도록 배치된 터치전극패드; 제1 스위치 및 제1 연산증폭기; 제2 스위치 및 제2 연산증폭기를 포함하는 터치입력장치를 공개한다. 상기 제1 스위치의 제1 일단부는 상기 터치전극패드에 연결되고 제1 타단부는 상기 제1 연산증폭기의 비반전 입력단자에 연결되고, 상기 제2 스위치의 제2 일단부는 상기 터치전극패드에 연결되고 제2 타단부는 상기 제2 연산증폭기의 비반전 입력단자에 연결되고, 상기 제1 연산증폭기의 반전 입력단자에는 제1전위(VH)가 인가되고, 상기 제2 연산증폭기의 반전 입력단자에는 제2전위(VL)가 인가되고(단, 제2전위<제1전위), 상기 제1 연산증폭기의 상기 비반전 입력단자와 상기 제1 연산증폭기의 출력단자 사이에는 제1 적분 커패시터가 연결되어 있고, 상기 제2 연산증폭기의 상기 비반전 입력단자와 상기 제2 연산증폭기의 출력단자 사이에는 제2 적분 커패시터가 연결되어 있다.
