摘要
The surface reconstruction of MgO by ion sputtering and redeposition brings about changes in discharge characteristics of AC-PDP. The more the number of discharges in cells is increased, the more the instability of discharge is increased. As discharges continuously occur, the microstructure of MgO is changed, and the time lag of the discharge is increased. In this paper, we present the mechanism of misdischarges, such as bright noise and black noise, by analyzing aging characteristics. Also, we found that misdischarges are closely connected with the exoelectron emission, which strongly influences the lag time of discharge, from a MgO surface. Moreover, we expressed the instability of reset discharge in terms of the lag time of the discharge and the probability of the strong dark discharge in the reset period.
