摘　　要：根据气体放电特性和交流等离子体显示器的放电单元结构 ,提出了AC PDP等效电路模型和表征该模型的 3个特性参量 :击穿电压、气体维持放电的最小电压和放电单元电容比。通过分析放电过程 ,推导出最大维持电压、最小维持电压和维持电压余裕度的表达式。利用外接串联电容 ,提出一种放电特性参量的测量方法 ,并对 12英寸PDP实验屏进行实际测量 ,获得了放电特性参量的测量结果。本文所提放电特性参量及其测量方法对AC PDP显示屏的放电单元设计具有参考作用。A new equivalent circuit of the discharge cell of AC plasma display panel (AC-PDP) has been developed based on the cell structure and the IV characteristics of gas discharge. Three key factors, including the break-down voltage, the minimum voltage of the gas discharge and the capacitance ratio of the cell were used to characterize the proposed equivalent circuit. Analytical expressions of the maximum and minimum voltages as well as the sustain voltage margin were obtained by analyzing the cell discharge. A new technique for discharge characteristics measurement, in which an external capacitor is used, has been successfully developed and applied to the technical evaluation of a 12 inch test AC-PDP with satisfactory results.
