五电极等离子体显示板触发放电的研究

Analysis of Trigger Discharges in Five-Electrode Alternating Current Plasma Display Panel

采用流体模型研究了一种五电极交流等离子体显示板(AC PDP)的单点触发放电过程及其真空紫外线 (VUV)的辐射特性．数值模拟结果表明,在放电期间恰当地调整电极上的驱动电位,可以改变介质层表面电荷积 累,获得较高的壁电压．通过数值模拟还获得了五电极AC PDP维持放电期间的VUV辐射效率,其中173 nm 的VUV辐射占总真空紫外辐射效率的27％,有利于提高AC PDP的发光效率．

The triggering discharges and the vacuum ultra-violet (VUV) radiation of the five-electrode alternating current plasma display panel (AC PDP) were investigated by fluid model simulations. The results show that after triggering discharge, the wall charges can be varied by adjusting the driving waveform, and the high wall voltage can be obtained. The ratio of 173 nm VUV to total VUV radiation is about 27%. It is useful to improve the efficiency of AC PDP.
