Abstract

Un mode de réalisation de la présente invention peut porter sur un appareil d'entrée pour dispositif électronique portable, comprenant : un module capteur d'empreinte digitale ; et un capteur complexe. Le module capteur d'empreinte digitale comprend : un support ; un capteur d'empreinte digitale, disposé sur le côté supérieur du support, comprenant une unité de détection formée sur un substrat souple et une unité de circuit de capteur électriquement connectée à l'unité de détection ; et une couche de revêtement positionnée sur le côté supérieur du capteur d'empreinte digitale. Le capteur complexe comprend : une électrode détectant un accès ou contact d'un conducteur par l'intermédiaire d'une variation de capacité ; une bobine en boucle détectant un accès ou contact d'un stylo électromagnétique par détection d'un champ magnétique engendré par le stylo électromagnétique ; et un capteur électromagnétique. De plus, le module capteur d'empreinte digitale et le capteur complexe sont positionnés sur le même substrat de base.
