Research demonstrates improved field of view performance in under-display ambient light sensors, indicating the importance of panel design.
This study focuses on the under‐dispkiy 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.
