【摘要】 对PDP 维持电极间插入带电辅助电极的新单元放电特性进行了模拟研究,并与传统的长间隙放电单元的模拟结果做了比较.模拟结果表明:新单元的Xe 激发效率高于传统结构的Xe 激发效率,并且Xe 激发效率与电压成反比;在维持间隙大于360 μm 时,新单元的最小维持电压低于传统单元的最小维持电压,当维持间隙大于或等于450 μm 时,辅助电极降低最小维持电压的优点尤为明显:当辅助间隙在60～100 μm 时,最小维持电压较小;与长间隙单元相比,新单元对荧光粉的损伤减轻50%以上,模拟结果对新结构PDP 单元优化设计提供了指导.更多还原

【Abstract】 The discharge characteristics of a new cell of PDP with one powered auxiliary electrode inbetween of two sustaining electrodes are simulated and compared with traditional long gap cell..TheXe excitation efficiency of new cell is higher than that of long gap cell and Xe excitation efficiency isinversely proportional to voltage.The minimum sustaining voltage of new cell is lower than that oflong gap cell when the sustaining gap is larger than 360 μm.This advantage is more obvious for thesustaining gap being equal to or larger than 450 μm.The minimum sustaining voltage is low when theauxiliary gap is 60～100μm.The phosphor damage of new cell is below 50% that of long gap cell.Thestudy is beneficial to the optimal design of new PDP cell.更多还原
