中文摘要：

本文采用基于动力学模型的OOPIC仿真软件模拟具有不同扫描电极宽度和荫罩结构的荫罩式等离子显示器（PDP）放电单元内的放电过程,分析单元内的条纹数量、分布状态和介质层表面壁电荷分布情况,研究扫描电极宽度和荫罩结构对阳极条纹的影响。结果表明,扫描电极宽度增加,放电单元内的主放电区域增大,条纹可分布空间压缩,条纹现象减弱。大小孔荫罩结构也会使条纹现象减弱。研究发现,荫罩式PDP结构阳极条纹的分布区域与介质层表面电荷积累的范围密切相关,阳极条纹只出现在阳极表面介质层有壁电荷积累,而对应的阴极表面介质层无壁电荷积累的区域。

英文摘要：

The discharge process of the shadow mask plasma display panel（PDP）with different scanning electrode widths and shadow mask structures were simulated with the software package object oriented particle in cell（OOPIC）,developed with the kinetic model.The number and position of the anode striations and the accumulated charge distributions on the dielectric surfaces were analyzed.The results show that the scanning electron width and the shadow mask structure significantly affect the anode striation.For example,the increase of the scanning electron width widens the main discharge area,narrows the space left for striation,and consequently reduces the number,or even eliminates the striation.Moreover,the large-small-hole shadow mask structure also strongly weakens the striation.We found that the charge accumulation on the dielectric surface closely correlated with the striation areas：the striation only exists on the area where negative charges accumulated on the dielectric surface above the anode,but no positive charge on the corresponding dielectric surface above the cathode.
