88‐2: Modeling Light Propagation in a Smartphone's Under‐Display Sensors

A universal light propagation model is built for a smartphone's under‐display sensors. Under‐display cameras, ambient light sensors, and proximity sensors are analyzed using the model. Far‐field Fraunhofer diffraction, near‐field geometric optics, and Fresnel diffraction are recognized, respectively. The model's effectiveness is experimentally verified for the three sensors.

Abstract

A universal light propagation model is built for a smartphone's under‐display sensors. Under‐display cameras, ambient light sensors, and proximity sensors are analyzed using the model. Far‐field Fraunhofer diffraction, near‐field geometric optics, and Fresnel diffraction are recognized, respectively. The model's effectiveness is experimentally verified for the three sensors.
