Effect of barrier rib height variation on the luminous characteristics of ac plasma display panel

We studied the mechanism of high luminous efficiency discharge with high Xe partial pressure in ac plasma display panel using three-dimensional numerical simulation. Because the electron heating efficiency improves more than the excitation efficiency by electrons under high Xe partial pressure gas condition, it is possible to achieve high efficiency discharge with the increase in the sustain voltage. We studied the effect of barrier rib height variation using ray-optics code in conjunction with the three-dimensional plasma simulation to analyze the effects of cell geometry for varying pressure conditions. The optimal barrier rib height decreased as the Xe partial pressure increased which resulted due to the formation of local, strong sheath under high Xe partial pressure condition.
