The influence of Ar addition to conventional Plasma Display Panel gases, Xe/Ne and Xe/He mixtures, on the radiation characteristics and the discharge onset voltage is studied using a Boltzmann equation method coupled with rate equations for electrons and excited species. When Ar is added to Xe/Ne mixtures, the efficiency of ultraviolet light radiation from Xe (1s2,4) and Xe2* increases 7-17% for E/p0 between 3 and 100?V?cm-1?Torr-1. In Xe/He mixtures, the efficiency increases over 20% for E/p0<10?V?cm-1?Torr-1. In addition, the visible light radiation of the 600?nm band from excited Ne, which makes the contrast worse, is effectively reduced. On the other hand, the discharge onset voltage increases with Ar addition because of a decrease in the effective secondary electron emission coefficient.

Addition of Ar to Xe/Ne and Xe/He mixtures: radiation characteristics and discharge onset voltage for an application of plasma display technology

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.
