采用放大单元的方法研究了表面放电结构、对向放电结构和新型荫罩式等离子体显示屏(SMPDP)的放电过程。分别制作了放大倍数为40的表面放电结构、对向放电结构和荫罩式结构PDP的放大单元。建立了放大单元的光辐射特性测试系统,采用高速ICCD拍摄了相应结构的放电过程并分析研究了各自的放电特性。结果表明,SMPDP的放电过程为非均匀场中的对向放电过程,具有较表面放电结构和对向放电结构更优越的放电性能。
Discharge processes of plasma display panel(PDP) in three major cases,such as the surface discharge,the opposite discharge and the discharge of shadow mask PDP, were studied, respectively. Dedicated measurement system and macro-discharge cells with a magnifying scale of 40 were built to evaluate the characteristics of both light emission and the discharge. The discharge was monitored with ICCD camera. The results show that the shadow mask PDP discharge is an opposite discharge in non-uniform field and that it has many advantages over that of the two other discharges.
