APPAREIL DE RECONNAISSANCE DE CARACTÉRISTIQUES BIOLOGIQUES À L'ÉCRAN ET DISPOSITIF ÉLECTRONIQUE

摘要

An under-screen biometric identification apparatus (300) and electronic device. The under-screen biometric identification apparatus (300) includes an optical function layer (310), including a first linear polarizer (311) and a first quarter-wave plate (312), wherein the first linear polarizer (311) and the first quarter-wave plate (312) are configured to be stacked; a biometric identification module (320), configured to perform biometric identification based on light transmitted to the biometric identification module (320) via the optical function layer (310). The under-screen biometric identification apparatus (300) could improve the performance of the under-screen biometric identification.
