(FR) PANNEAU TACTILE ET DISPOSITIF ÉLECTRONIQUE
(JA) タッチパネルおよび電子機器
Abstract:
(EN) The purpose of the present invention is to achieve further miniaturization of and improved performance for a pressure detection-type touch panel. A touch panel (1) comprises: a TP upper electrode layer (19) located above a CF substrate (18); a TP lower electrode layer (15) located below the CF substrate (18) and above a liquid crystal layer (14); and a piezoelectric element layer (16) located between the TP upper electrode layer (19) and the TP lower electrode layer (15).
(FR) L'objectif de la présente invention est d'obtenir une miniaturisation supplémentaire et une performance améliorée d’un panneau tactile de type à détection de pression. L’invention concerne un panneau tactile (1) qui comprend : une couche d'électrodes supérieures TP (19) située au-dessus d'un substrat CF (18) ; une couche d'électrodes inférieures TP (15) située au-dessous du substrat CF (18) et au-dessus d'une couche de cristaux liquides (14) ; et une couche d'éléments piézoélectriques (16) située entre la couche d'électrodes supérieures TP (19) et la couche d'électrodes inférieures TP (15).
(JA) 押圧検出型タッチパネルにおいて、さらなる小型化および性能向上を実現する。タッチパネル(1)は、CF基板(18)の上方に位置するTP上側電極層(19)と、CF基板(18)の下方かつ液晶層(14)の上方に位置するTP下側電極層(15)と、TP上側電極層(19)とTP下側電極層(15)との間に位置する圧電素子層(16)と、を備えている。
