This research reveals a method that improves diffraction in curved displays, indicating benefits for AR/VR and automotive technologies.
By integrating an inverse propagation phase retrieval algorithm with a customized simulated annealing (SA) algorithm, this research designed Diffractive Optical Elements (DOEs) to suppress unwanted diffraction spots in curved transparent displays. Results show that the proposed method increases the zero‐order diffraction ratio from 42.261% to 65.752%, offering a scalable solution for curved transparent displays in automotive, AR/VR, and under‐display camera applications.
