Title
(DE) FINGERABDRUCKIDENTIFIZIERUNGSVORRICHTUNG UND ELEKTRONISCHE VORRICHTUNG
(EN) FINGERPRINT IDENTIFICATION DEVICE AND ELECTRONIC EQUIPMENT
(FR) DISPOSITIF D'IDENTIFICATION D'EMPREINTE DIGITALE ET ÉQUIPEMENT ÉLECTRONIQUE
Abstract
(EN) Provided are a fingerprint identification apparatus and an electronic device, and the fingerprint identification apparatus is applied to an electronic device having a display screen. The fingerprint identification apparatus comprises: a support plate used to fixedly connect with a middle frame of the electronic device; and at least one fingerprint sensor chip disposed on an upper surface of the support plate and disposed under the display screen through the support plate; wherein the at least one fingerprint sensor chip is configured to receive a fingerprint detecting signal returned by reflection or scattering via a human finger on the display screen, wherein the fingerprint detecting signal is used to detect fingerprint information of the finger.
(FR) L'invention concerne un dispositif d'identification d'empreinte digitale et un dispositif électronique. L'appareil d'identification d'empreintes digitales est appliqué à un dispositif électronique avec un équipement d'affichage. Le dispositif d'identification d'empreinte digitale comprend une plaque de support, qui est utilisée pour être reliée de façon fixe à un cadre intermédiaire de l'équipement électronique ; et au moins une puce de capteur d'empreinte digitale, qui est disposée sur la surface supérieure de la plaque de support et qui est disposée sous l'écran d'affichage au moyen de la plaque de support, la ou les puces de capteur d'empreinte digitale étant utilisées pour recevoir un signal de détection d'empreinte digitale renvoyé par réflexion ou diffusion à partir d'un doigt humain au-dessus de l'écran d'affichage, le signal de détection d'empreinte digitale étant utilisé pour détecter des informations d'empreinte digitale du doigt.
