带有浮动电极的等离子体显示板发光效率数值模拟研究

Simulation of Luminous Efficacy of AC Plasma-Display-Panel with Floating Electrodes

针对表面放电ACPDP中一种大放电间隙的情形 ,采用流体模拟方法 ,研究浮动电极的宽度、间隙以及浮动电极与显示电极平面之间的介质厚度及其相对介电常数对发光效率的影响 ,结果发现浮动电极的宽度和间隙对发光效率影响较大 ,而浮动电极与显示电极平面之间的介质厚度及其相对介电常数则对发光效率影响较小 ,采用浮动电极后最小维持电压得到了较大幅度的降低。

Influence of various factors of floating electrode on the luminous efficacy, including its width, gap, thickness and relative permittivity of the dielectric layers sandwiched between the display electrode and the floating cathode, was evaluated by fluid simulation. The results show that the width and gaps of the floating cathode affect luminous efficacy more strongly than the thickness and the permittivity of the dielectric layers. The minimum sustaining voltage can be considerably reduced with the floating cathode.
