Abstract
Devices and optical sensor modules are provided for on-screen optical sensing of fingerprints by using an under-screen optical sensor module that includes a pinhole-lens assembly to enhance the optical imaging performance such optical sensor modules placed under organic light emitting diode (OLED) display modules and other display modules. Techniques for reducing the environmental light in the optical sensing are provided.
