Investigation of Discharge Characteristics Affected by Barrier Ribs in the Discharge Cell of Alternating‐Current Plasma Display Panel

Abstract

AbstractTo investigate the barrier ribs effect on the discharge characteristics in the discharge cell of Alternating‐Current Plasma Display Panel, three kinds of barrier ribs in the discharge cell: gas gap, dielectric gap, and metallic gap, were studied respectively. The distribution of potential and the distribution of density of charged particles were obtained by the two‐dimensional particle‐in‐cell kinetic simulation method. The simulation results shows that, in the Ne‐Xe (4%) gas mixture with the gas pressure of 300 Torr, the distribution of electric potential, in the corner of the left and right side, is very different, while the distribution in the center of cell in these three cases is almost same. And the formation process of the striation during the discharge is also discussed. The distribution of density shows that the striation phenomenon occurs along with the firing of discharge, and the existence of the dielectric ribs may reduce the charged particles density humps to some degree.
