— Two fluid models, LFA (local field approximation) and EME (electron mean energy), were applied to simulate the discharge process of a novel PDP with a shadow mask. In order to consider the variation of the secondary electron emission coefficient under different electric‐field and gas content, the secondary electron emission coefficient was calculated as a function of the energy of incident ions. The variation of the mean density of different particles as a function of time, electron temperature, and their space distributions in the discharge cell will be presented. And the simulation results of these two models are also compared in this paper. Then the EME model was used to investigate the relation between the discharge efficiency and the structure of the shadow mask, the xenon concentration, and the pressure.
