Title (EN) TOUCH INPUT DEVICE COMPRISING STRAIN GAUGE
(FR) DISPOSITIF DE SAISIE TACTILE COMPRENANT UNE JAUGE DE CONTRAINTE
(KO) 스트레인 게이지를 포함하는 터치 입력 장치
Abstract:
(EN) A touch input device capable of detecting touch pressure according to an embodiment of the present invention comprises: a display module; and a pressure sensor layer disposed under the display module, wherein: an adhesive layer is disposed between the display module and the pressure sensor layer so as to adhere the pressure sensor layer to the display module; the pressure sensor layer has a structure in which a first strain gauge is formed on the upper surface of a substrate and a second strain gauge is formed on the lower surface of the substrate; when pressure is applied to the display module, the display module is bent, and due to the bent display module, the electrical characteristics of each of the first strain gauge and the second strain gauge are changed; and the Young's modulus of the substrate is greater than the Young's modulus of the adhesive layer.
(FR) Un dispositif de saisie tactile capable de détecter une pression tactile selon un mode de réalisation de la présente invention comprend : un module d'affichage ; et une couche de capteur de pression disposée sous le module d'affichage, où : une couche adhésive est disposée entre le module d'affichage et la couche de capteur de pression de manière à faire adhérer la couche de capteur de pression au module d'affichage ; la couche de capteur de pression a une structure dans laquelle une première jauge de contrainte est formée sur la surface supérieure d'un substrat et une deuxième jauge de contrainte est formée sur la surface inférieure du substrat ; lorsqu'une pression est appliquée au module d'affichage, le module d'affichage est déformé, et en raison de la déformation du module d'affichage, les caractéristiques électriques de chacune des première jauge de contrainte et deuxième jauge de contrainte sont changées ; et le module d'Young du substrat est supérieur au module d'Young de la couche adhésive.
(KO) 본 발명의 실시예에 따른 터치 압력 검출이 가능한 터치 입력 장치는, 디스플레이 모듈, 및 상기 디스플레이 모듈의 하부에 배치된 압력센서층을 포함하고, 상기 디스플레이 모듈과 상기 압력센서층의 사이에 접착층이 존재하여 상기 압력센서층을 상기 디스플레이 모듈에 접착시키고, 상기 압력센서층은 기판의 상면에 제1 스트레인 게이지가 형성되고 상기 기판의 하면에 제2 스트레인 게이지가 형성된 구조를 포함하고, 상기 디스플레이 모듈에 압력이 인가되면 상기 디스플레이 모듈이 휘어지고, 상기 디스플레이 모듈이 휘어짐에 따라 상기 제1 스트레인 게이지와 상기 제2 스트레인 게이지 각각의 전기적 특성이 변화하고, 상기 기판의 영률(Young's Modulus)은 상기 접착층의 영률보다 크다.
