Gas discharge and experiments for plasma display panel

摘要

Physical phenomena which take place in an AC Plasma Display Panel(PDP) 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 350Torr. 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 = 0.1approx0.2percent due to Penning effect and then the voltage increases when Xe conten is increased. The maximum memory margin for Ne-Xe gas mixture is located on Xe = 4approx5percent. The luminous efficiency increases when the gas pressure is increased. The spectrum of PDP with Ne-4percentXe at 500Torr from 400nm to 850nm is presented. Ne-Xe(up to 10percentXe) has lower luminous efficiency than pure Ne and the minimum value is located on 2approx3percentXe. By SIPDP simulation model, we can see electrical and optical properties of PDP change with varying gas compositions.
