Abstract

Le domaine général de l'invention est celui des dispositifs à écran tactile comprenant au moins un écran tactile multiplexé (10), une électronique de commande (20) et une électronique d'acquisition et de traitement (30), l'écran tactile comprenant un premier substrat rigide (15) comportant une pluralité de lignes conductrices (13), un second substrat souple (14) comportant une pluralité de colonnes (12) conductrices perpendiculaires auxdites lignes. L'électronique de commande (20) comporte un générateur (21) d'une tension haute fréquence alimentant un premier multiplexeur (22) adressant la pluralité de lignes conductrices. L'électronique d'acquisition et de traitement (30) comporte un second multiplexeur (31) adressant la pluralité de colonnes conductrices et un démodulateur synchrone (32) fonctionnant à la même fréquence que le générateur de tension haute fréquence et délivrant une pluralité de tensions de sortie (VOUT) sur chaque colonne et des moyens de calcul permettant de calculer l'impédance existant entre chaque tension de sortie (VOUT) et la tension d'entrée (VIN). L'électronique d'acquisition et de traitement comporte également des moyens d'analyse (34) de l'impédance permettant de calculer sa partie résistive et sa partie capacitive.
