Description:

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.
