Experiments and Numerical Analyses of Charged Particle's Behavior in a Plasma Display Panel
Experimental and numerical studies of erosion process of an MgO layer were performed in order to obtain a fundamental guideline for lifetime evaluation of a plasma display panel (PDP). From the experimental results of an over-voltage accelerated discharge test and surface analysis of the MgO layer, it was found that the erosion and deterioration progressed due to the bombarding ions and adsorbed impurities, respectively, in the MgO surface during the accelerated discharge. The numerical analysis of the plasma behavior and its structure in PDP discharge was performed to explain these experimental results. The localized erosion on the MgO surface was due to the discontinuity of the ion bombardment, which was further expedited by the charge accumulated in dielectric (wall charge) behavior. The combination of these behaviors of charge particle was found to explain the localized erosion process in the MgO layer in the accelerated PDP discharge.
