| 摘 要： | 为了提高等离子体显示单元的亮度和放电效率,本文采用三维流体模型对新型荫罩式等离子体显示板(SMPDP)的菱形单元结构进行了优化。研究了放电单元中的荫罩小孔结构改变对寻址期和维持期放电的影响。详细分析了小孔取向平行寻址电极和垂直寻址电极条件下电场和壁电荷的分布,以及对寻址时间、真空紫外辐射量和放电效率的影响。模拟结果表明:当小孔垂直寻址电极、长度和宽度分别为240μm和120μm时为最佳结构,通过优化小孔结构可以获得较高的寻址速度和放电效率,又可保证荧光粉的涂覆面积。

| Abstract: | The structure of the diamond-shaped cell of the novel shadow mask plasma display panel(SMPDP) was simulated with the three-dimensional fluid model.The influence of the structural changes of the shadow mask on the discharge characteristics in the address and sustain periods was studied.The distributions of the electric field and the wall change for the holes,oriented parallel and normal to the address electrodes,were calculated and their impacts on the address time,vacuum ultraviolet(VUV) emission energy,and... |
