面電極型高周波駆動プラズマディスプレイにおけるマイクロ放電シミュレーション

In recent years, the demand for plasma display panels has expanded rapidly with the start of high definition digital broadcasting. However, the luminous efficiency of plasma display panels is still low compared with cathode-ray tube displays. With respect to the market expansion, further improvement of the efficiency is required. In the present work, we proposed a new driving scheme applying radio frequency voltage to coplanar electrodes and simulated the discharge behavior in a plasma display cell using a two dimensional fluid model. As a result, the discharge evolution in the cell was clarified at addressing and sustaining periods. The radiation efficiency of ultraviolet light was about 4 times as large as that of a conventional plasma display panel. The barrier rib height was a considerable parameter because of the significant influence on firing and sustaining conditions.
