Study on Optimization Methods for the FoV Performance of Under-Display Ambient Light Sensors in AMOLED

Description:

This study focuses on the under-display ambient light sensors (ALS) in smartphones, specifically investigating the impact of AMOLED panels on field of view (FOV). By establishing a three-dimensional model of the complete film layer stack of the display panel, we obtained simulation results that closely matched the experimental data. The research reveals the mechanisms by which panel design affects oblique incident light. By optimizing the panel design, the FOV capability of ALS can be effectively enhanced. Ultimately, we developed a simple and rapid method to evaluate the impact of AMOLED panels on FOV performance, providing significant guidance for panel design.
