Title (EN) TOUCH PANEL HAVING PRESSING FORCE DETECTING FUNCTION AND PRESSURE SENSITIVE SENSOR FOR TOUCH PANEL
(FR) ECRAN TACTILE POSSÉDANT UNE FONCTION DE DÉTECTION DE LA FORCE DE PRESSION ET CAPTEUR SENSIBLE À LA PRESSION POUR ÉCRAN TACTILE
(JA) 押圧検出機能を有するタッチパネル及び当該タッチパネル用感圧センサ
Abstract:
(EN) Provided is a touch panel having a pressing force detecting function, the touch panel capable of reducing the deterioration of visibility of a display unit of a display device and improving the pressure measurement accuracy even when mounted in an electronic device.  The touch panel is provided with a first substrate, a second substrate which is disposed opposite the first substrate, a pair of electrodes which are disposed on either of or disposed respectively on both of opposite surfaces of the respective substrates, a pressure sensitive ink member which is disposed with a space from at least one of the pair of electrodes and has electric characteristics that change according to applied pressure force, and a space holding member by which the first and second substrates are bonded and which holds a space between the pressure sensitive ink member and at least one of the pair of electrodes, wherein the pair of electrodes are disposed in a frame shape along the edge of the first or the second substrate, and the pressure sensitive ink members are dotted along the edge of the first or the second substrate and configured such that when the first or the second substrate is deformed by application of external force, at least one thereof comes into contact with both of the pair of electrodes and provides conduction between both the electrodes.
(FR) La présente invention a pour objet un écran tactile possédant une fonction de détection de la force de pression, l'écran tactile étant capable de réduire la détérioration de la visibilité d'une unité d'affichage d'un dispositif d'affichage et d'améliorer la précision de la mesure de pression même lorsqu'il est installé dans un dispositif électronique. L'écran tactile est pourvu d'un premier substrat, d'un second substrat qui est disposé à l'opposé du premier substrat, d'une paire d'électrodes qui sont soit disposées sur l'une des deux surfaces opposées des substrats respectifs, soit disposées respectivement sur les deux surfaces opposées des substrats respectifs, d'un organe de tracé sensible à la pression qui est disposé en respectant un espace avec la ou les électrodes de la paire d'électrodes et possède des caractéristiques électriques qui changent en fonction de la force de pression appliquée, et d'un élément d'écartement par lequel les premier et second substrats sont reliés et qui maintient un espace entre l'organe de tracé sensible à la pression et la ou les électrodes de la paire d'électrodes, la paire d'électrodes étant disposée en forme de cadre le long du bord du premier ou du second substrat, et les organes de tracé sensibles à la pression étant éparpillés le long du bord du premier ou du second substrat et conçus de telle sorte que lorsque le premier ou le second substrat est déformé par l'application d'une force externe, qu'au moins l'un d'entre eux vienne au contact des deux électrodes de la paire d'électrodes et fournisse une conduction entre les deux électrodes.
(JA)  本発明は、電子機器に搭載されても表示装置の表示部の視認性の低下を抑えることができるとともに、圧力の測定精度を向上させることができる押圧検出機能を有するタッチパネルを提供することを目的とする。このため、本発明のタッチパネルは、第1基板と、第1基板と対向配置された第2基板と、各基板の互いの対向面のうちのいずれか一面又は両面に分かれて配置された一対の電極と、一対の電極の少なくとも一方とは隙間を空けて配置され、加えられた押圧力により電気特性が変化する感圧インク部材と、第1及び第2基板を接着するとともに、感圧インクと一対の電極の少なくとも一方との隙間を保持する隙間保持部材とを備え、一対の電極は第1又は第2基板の縁部に沿って枠状に配置され、感圧インク部材は、第1又第2基板の縁部に沿って点在し、外力が加わることにより第1又は第2基板が変形したとき、少なくとも1つが一対の電極の両方に接触して両者を導通させるように構成されている。
