摘　　要：针对目前PDP效率较低的问题 ,本文采用三维流体模型计算了新型荫罩式PDP(SMPDP)不同放电单元结构的放电特性和放电效率。在此基础上采用蒙特卡罗模型 ,研究了SMPDP放电单元中的光子辐射和捕获过程 ,给出了达到荧光粉层上的光子情况。研究了SMPDP结构电极宽度和位置以及气压和气体成分对放电效率的影响。设计了一种具有较高效率的荫罩式PDP结构 。The breakdown characteristics and discharge efficiency of the newly developed shadow mask plasma display panel (SMPDP) were simulated with a three dimensional (3 D) fluid model.The emission and capture of photons in the discharge cells as well as the distribution of impinging photons on the phosphor layer were simulated with Monte Carlo model.Influence of various parameters,such as the position and width of its electrode,pressure and concentration of xenon,on discharge efficiency was also studied.Possible ways to improve discharge efficiency were proposed and an optimal SMPDP structure was designed.
