摘　　要：为了降低五电极交流等离子体显示板(AC PDP)的维持放电电压,提出了一种新的触发驱动方法.该方法利用2个辅助间隙内放电过程相互独立的特性,在触发期间采用单个辅助间隙进行触发放电以提高主维持间隙的壁电压.二维流体模拟结果表明,新的触发驱动方法可将五电极AC PDP主维持间隙的壁电压提高30 V左右,从而使其维持电压降低了10～20 V,降低了对驱动电路的要求,同时真空紫外辐射效率比传统三电极AC PDP提高了50%以上.A new triggering method is proposed to lower the sustaining voltage of the five-electrode alternating current plasma display panel（AC PDP）. In the method, a triggering discharge is adopted in one of the auxiliary gaps to increase the wall voltage across the sustaining gap. Two dimensional fluid simulation results show that the wall voltage across the sustaining gap is increased by 30 V, and the sustaining voltage can be lowered by 10-20 V with the new triggering method. The vacuum ultra-violet radiation efficiency is increased by more than 50% compared to the conventional three-electrode AC PDP.
