Vacuum Ultraviolet Emission Characteristics on High Xenon Mole Fraction at Low Pressure in AC-PDP

Nowadays, many research groups try to achieve the high Xe mole fraction discharge gas for high efficiency in AC-PDPs. However, the high Xe mole fraction discharge gas causes the high discharge voltage, which is a serious problem in AC-PDP`s for high efficiency. In this study, the discharge gas with high Xe mole fraction and the low pressures has been applied and it`s discharge voltage and vacuum ultraviolet emission characteristics have also been measured. It is shown that the discharge voltage is 354V and 389V at Ne+Xe (15%) with 400 Torr and Ne+Xe (30%) with 200 Torr, respectively. Their vacuum ultraviolet emission characteristics have similar characteristics to each other, in which their wavelengths are ranged from 140 nm to 200 nm. It is found in this experiment that the luminous efficiency for the discharge gas of Ne+Xe (30%) with 200 Torr is drastically increased by about 30%.
