摘　　要：本文讨论了新型荫罩式PDP单元结构的变化对放电的影响 ,从放电强度和放电效率的角度对单元结构进行优化设计。研究了取代介质障壁的荫罩的高度、宽度变化和荫罩内边界形状的变化对放电的影响 ,给出了不同结构下平均粒子浓度随时间的变化曲线和放电效率的变化趋势。模拟结果表明荫罩边界为内斜式的结构在响应时间、峰值浓度和放电效率上都具有较大优势 。Influence of various geometric factors of the mask in the newly developed shadow mask plasma display panel (SM-PDF) cell, including its size, its shape and its height, on discharge characteristics was theoretically simulated to optimize the geometric design. The time evolution of the average particle density and the discharge efficiency for different PDF cell structures were calculated. The simulated results show that the inward-inclined structure offers higher peak value of particle density, faster response speed, and higher discharge efficiency, than any other structures we have discussed here.
