The gas mixture ratio of PDP discharges plays a very important role in the discharge characteristics of a plasma display panel. The increase of Xe contents results in the increases of luminance and luminous efficiency while it also results in the increase of the breakdown voltage. The addition of He gas increases the brightness and the luminous efficiency. Especially, the luminance and the luminous efficiency have a maximum value when the partial pressure of He is about 10% of the total pressure for a standard plasma display panel with Xe fraction of $10\sim30%$.

Voltage transfer curves have been used for analyzing the micro-discharge characteristics of cells in ac-PDP. This paper deals with the effect of working gas species, pressure and frequency of applied voltage on the micro-discharge characteristics. Using the mixture gases of He+Xe or He+Ne+Xe, wall voltage steeply varied compared with only He gas, and also voltage margin increased. Discharge voltage and voltage margin increased with increasing Xe percentage, and also wall voltage more steeply varied. In addition, the variation of effective wall capacitance which is significantly dependent on the discharge strength is discussed.

We investigated the discharge characteristics by adding a little $N_2$ to the mixed gas, Ne+Xe+He, as the working gas in AC PDP. In this study, it is founded that the luminance and efficiency of the panel included a little $N_2$ increased and the discharge firing voltage is reduced. In addition, the characteristics of jitter and delay time are investigated.

MgO dielectric pprotection layer is ppreppared by R.F. reactive magnetron spputtering with Mg target under various conditions of spputtering ppressure, time and substrate tempperature. Discharge characteristics of ppDpp is also studied as a pparameter of MgO pprepparation conditions. As the working ppressure and substrate tempperature was increase, the discharge voltage was decreased. Two kinds of MgO ppreppared both spputtering and E-beam methods were stable after annealing at 35$0^{\circ}C$ for 120min. discharge voltage under 3 mixed gas(He+Xe0.2%+Ne30%) was V=130V, V=102V and ${\gamma}$ coefficient was twiced as much as that of dielectric layer.

For ac Plasma Display Panel (PDP), the lifetime should be guaranteed over 30000 hours. The lifetime is correlated with the deterioration characteristics for the weakest element in ac PDP. In this paper, in order to improve the lifetime of ac PDP, a short-term relative lifetime test method for a given element in the ac PDP is proposed. By this method, the effects of MgO thin film thickness and deposition rate on the relative lifetime of ac PDP are investigated. The relative lifetime is increased with MgO thin film thickness but it was almost saturated over 5000. The relative lifetime decreased with increase in the MgO deposition rate and increased with Xe% in the working gas of He+Ne+Xe..
