Abstract
This study investigates the complex diffraction patterns arising from aperture arrays in Under Display Infrared (UDIR) sensors for facial recognition applications. Utilizing simulations and experimental data, we analyze diffraction effects based on aperture shapes and open area ratios. Our findings reveal that the diffraction issues are too complex to describe using only simple parameters like Transmittance. Our study emphasizes the need for sophisticated methodologies to accurately assess the performance impact of diffraction in UDIR applications.
