Abstract

L'invention porte sur un écran tactile à capteur de pression appliquée et sur un procédé de saisie d'utilisateur l'utilisant. Selon l'invention, et sans utiliser un substrat sur lequel un motif d'électrodes de structure complexe a été formé, il est possible de configurer un écran tactile pouvant détecter exactement: les pressions de contact par le doigt de l'utilisateur pour différentes positions, ainsi que les coordonnées des positions respectives des contacts, en n'utilisant qu'une série d'éléments capteurs de pression disposés sur l'écran tactile.
