Numerical Simulation of Microdischarge in Radio Frequency Excited Plasma Display Panel with Coplanar Electrodes

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 improvements in efficiency are required. In the present work, we proposed a new driving scheme applying radio frequency voltage to coplanar electrodes and simulate 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 during the addressing and sustaining periods. The radiation efficiency of ultraviolet light was about four times as large as that of a conventional plasma display panel. The barrier rib height was an important parameter because of its significant influence on tiring and sustaining conditions. (c) 2007 Wiley Periodicals, Inc.
