摘　　要：采用基于粒子-蒙特卡罗模型的OOPIC-PRO软件对荫罩式等离子体显示板(PDP)的放电进行模拟,研究扫描电极宽度、氖氙混合气体比例、气压等参数变化对主放电区域及条纹分布的影响,并与高速ICCD相机拍摄的条纹分布进行比较分析。模拟和实验结果表明:随着电极宽度增加,主放电区域增大,条纹区域减小,放电效率降低;随着氙比例和气压的升高,主放电区域减小,条纹区域增大,放电效率提高。研究结果揭示了PDP放电单元中条纹区域的粒子能量适宜激发产生辐射紫外光子的氙谐振态和激发态粒子,这对提高PDP的放电效率乃至发光效率尤为关键。OOPIC-PRO software based on Particle in Cell-Monte Carlo collision model is used to investigate the discharge in the shadow mask plasma display panel. The main-discharge region and the striation variation have been studied when the scan electrode width, the xenon proportions in gas mixture and the gas pressures are changed. The simulated resuits were compared with direct observations with an intensified charged coupled device camera. The simulated and experimental results indicate that the main-discharge region will reduce, the striation region will enlarge and the discharge efficiency will increase with the decrease of the scan electrode width, the increase of xenon proportions or the gas pressures. The results also show us that the particle energy in striation region is easy to generate ultraviolet photons, which may help improve the discharge efficiency of the shadow mask PDP.
