Numerical Analysis of Influence of Penning Gas Composition on Discharge Characteristics in AC Plasma Display Panel

为优化彩色ACPDP中的气体组成以提高其性能 ,建立了ACPDP单元气体放电的一维模型 ,模型是基于对电子和离子输运的二元流体描述 ,并耦合了泊松方程及一系列动力学方程。利用此模型对潘宁气体Ne +Xe中Xe的百分含量对ACPDP单元放电特性的影响进行了数值分析 ,给出了气体组成比例对ACPDP工作电压及放电过程中产生的UV射线效率的影响特性。计算过程中 ,假定放电气体处于局域平衡状态 ,各种粒子的反应概率设为E/p的函数 。

The composition of a gas mixture filled in an AC PDP may significantly affect the discharge characteristics,and improvement of AC PDP's performance can be realized by optimizing the gas composition.A one dimensional fluid model has been developed to study the discharge in an AC PDP cell.Numerical calculation was performed with this model for the case of Ne+Xe Penning gas mixture to evaluate possible influence of Xe percentage on the working voltage and the UV production efficiency in the discharge.
