Title (EN) IMPROVING OPTICAL SENSING PERFORMANCE OF UNDER-SCREEN OPTICAL SENSOR MODULE FOR ON-SCREEN FINGERPRINT SENSING
(FR) AMÉLIORATION DES PERFORMANCES DE DÉTECTION OPTIQUE D'UN MODULE DE CAPTEUR OPTIQUE SOUS-ÉCRAN POUR DÉTECTION D'EMPREINTE DIGITALE SUR ÉCRAN
Abstract:
(EN) Devices and optical sensor modules are provided for provide on-screen optical sensing of fingerprints by using a under-screen optical sensor module that captures and detects returned light that is emitted by the display screen for displaying images and that is reflected back by the top surface of the screen assembly. Optical collimators(2106) are provided in the under-screen optical sensor module to enhance the optical imaging performance. Techniques for reducing the environmental light in the optical sensing are provided.
(FR) La présente invention concerne des dispositifs et des modules de capteurs optiques permettant d'assurer une détection optique sur écran d'empreintes digitales au moyen d'un module de capteur optique sous-écran qui capture et détecte la lumière renvoyée qui est émise par l'écran d'affichage pour afficher des images et qui est réfléchie en retour par la surface supérieure de l'ensemble écran. Des collimateurs optiques (2106) sont prévus dans le module de capteur optique sous-écran afin d'améliorer les performances de l'imagerie optique. L'invention concerne également des techniques de réduction de la lumière ambiante dans la détection optique.
