彩色AC-PDP充气的优化

Optimization of the Gases Filled in Color AC PDP

综述充气成分、配比、压强对彩色ＰＤＰ特性的影响。利用辉光放电管和３英寸ＡＣ－ＰＤＰ表面放电模拟板，测得几种常用气体的ＤＣ放电巴邢曲线和ＡＣ表面放电的着火电压曲线。结果表明，对ＡＣ表面放电的电极系统不符合气体放电相似定律，其着火电压Ｕｆ也不符合巴邢定律。为提高亮度和光效，对表面放电ＡＣ－ＰＤＰ，充气压强应选在Ｕｆ＝ｆ（ｐ）曲线的右支。最后归纳ＡＣ－ＰＤＰ充气的优化步骤。

The effects which are caused by composition,ratio and pressure of the gases filled on the performance of color PDP are reviewed.By a glow discharge tube and 3 in.analogous panel of surface discharge AC PDP,The Paschen curve of firing voltage for DC discharge and the U f= f(p) curve of AC surface discharge for several gas mixtures in common use are measured.The results show that the AC surface discharge electrode system is not conformed to the Analogical law of gas discharge,and the firing voltage is not satisfied with Paschen law.To improve brightness and luminous efficiency of AC PDP,The pressure of the gases filled should be selected at the right branch of the U f= f(p) curve.At last,The procedure of optimization of filling gases are summarized.
