Gas Discharge and Experiments for Plasma Display Panel

Physical phenomena which take place in an AC Plasma Display PanelPDP cells are discussed in this paper. Basic principles for gas discharge in PDP are presented. According to experiments in this paper, we can see PDP changes behaviors including memory margin, luminance, luminous efficiency, Penning effect and Paschen curve with varying gas composition and pressure. For pure helium and neon gas, helium has higher breakdown voltage than neon below 35OTorr. Pure neon has higher memory margin than helium. The memory margins of both pure neon and helium decrease when their pressures are increased. In Ne-Xe gas mixture, the minimum breakdown voltage is located on Xe 0.O.2 due to Penning effect and then the voltage increases when Xe content is increased. The maximum memory margin for Ne-Xe gas mixture is located on Xe45. The luminous efficiency increases when the gas pressure is increased. The spectrum of PDP with Ne-4Xe at 5OOTorr from 4OOnm to 850nm is presented. Ne-Xeup to lOXe has lower luminous efficiency than pure Ne and the minimum value is located on 23Xe. By SIPDP simulation model, we can see electrical and optical properties of PDP change with varying gas compositions.
