含辅助电极的等离子体显示板单元放电特性模拟

Discharge Characteristic Simulation of PDP Cell with Auxiliary Electrode

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;在维持间隙在于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60-100μm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．

The discharge characteristics of a new cell of PDP with one powered auxiliary electrode in between of two sustaining electrodes are simulated and compared with traditional long gap cell.. The Xe excitation efficiency of new cell is higher than that of long gap cell and Xe excitation efficiency is inversely proportional to voltage. The minimum sustaining voltage of new cell is lower than that of long gap cell when the sustaining gap is larger than 360 urn. This advantage is more obvious for the sustaining gap being equal to or larger than 450 μm. The minimum sustaining voltage is low when the auxiliary gap is 60-100 μm. The phosphor damage of new cell is below 50% that of long gap cell. The study is beneficial to the optimal design of new PDP cell.
