Abstract
In this study, we proposed a numerical approach to predict a sound quality of the large‐sized OLED panel speaker. In order to perform accurate numerical analysis of the panel speaker, it is necessary to build the entire display module and the multiphysic simulation of elastic and acoustics must be analyzed. In this study, we totally constructed a three‐dimensional (3D) finite element model of the OLED panel to analysis the multi‐physics and it is sequentially simplified to reduce the computational cost. The modified incident condition is applied as an external pressure boundary condition to correct the total energy decrease by increasing the operation frequency. The results of the proposed method was verified by numerical simulations and experimental measurements.
