Mechanism of high efficiency discharge in PDP cell under high pressure conditions

Summary form only given, as follows. Using 2D fluid PDP cell simulation, we investigated the mechanism of different efficiency dependence on the sustain voltage under low and high-pressure gas condition. The VUV generation efficiency is determined mainly by two partial efficiencies. The first is the electron heating efficiency by electric field, and the second is the Xe excitation efficiency by electron. We found that these two partial efficiencies have different dependencies on the sustain voltage.
