Abstract (en)

[origin: WO2018049944A1] Devices (200) and optical sensor modules (702) are provided for provide on-screen optical sensing of fingerprints by using a under-screen optical sensor module (702) that captures and detects returned light that is emitted by a LCD display screen for displaying images and that is reflected back by the top surface of the screen assembly (423).
