The effects of wall charge and bias voltage on exo-electron emission currents were examined. In addition, the effects of doping elements on the currents were investigated. These results indicated that the statistical delay is inversely proportional to the exo-electron emission currents measured.

Study of the ion-induced-, photo- and exo-electron emission from a Sc doped MgO protective layer has been performed. It is established that doping with Sc increases photo- and especially exo-electron emission from MgO films while the ion-induced electron emission coefficient $\gamma$ stays unchanged.

In this study, we attempted to reduce firing voltage of AC-PDP by alloying MgO protective Layer with CaO. Also, spray coating of single crystal MgO powder has been used to improving Exo-electron emission characteristics and reducing the statistical discharge delay in plasma displays. The properties of discharge depending upon the single crystal MgO powder are investigated. Plasma display having powder coated MgCaO Protective Layer shows lower driving voltage and higher efficacy than of uncoated, conventional panel.

As the temperature of the panel increases in AC-PDPs, the minimum driving voltage increases. Also, as the more the number of discharge increases in cells, the probability of the strong dark discharge in the reset period increases. In this study, we investigated the relationship between the lag time of the discharge and the mechanism of mis-discharges which are the black noise and bright noise. We conclude that the variation of time lag characterizes the properties of exo-electron emission from MgO. Thus, we found that the main factor of the mis-discharges is the rate of change of the electron emission ability from the MgO surface.

In AC-PDP, it is necessary to achieve high luminance efficacy, high luminance and high resolution by adopting technologies such as high Xenon concentration, MgO doping, and long gap. However, it is very difficult to apply above technologies because they reduce driving voltage margin. For example, doping of MgO reduces driving voltage but introduces new problems such as increased temperature dependency of discharge, which result in larger variations in driving margin at different temperatures. In this paper, we present the experimental results of the characteristics of temperature-dependent discharges. In addition, we suggest the mechanism of bright noise, black noise, and high temperature mis-discharge, which depend on temperature-dependent characteristics of MgO.
