Effects of pressure and electrode resistance on AC-plasma display panels (AC-PDPs) for various panel temperatures

摘要

In this study, the effects of panel temperature on AC-plasma display panels (AC-PDPs) were investigated. Macroscopic properties, such as the luminance, discharge delay time lag, and discharge current decreased while the breakdown voltage increased with increasing panel temperature. These data implied that changes in the materials properties with the panel temperature strongly affected the macroscopic properties, including the gas-discharge characteristics of AC-PDPs. The reason can be explained by the change in the collision kinetics due to the increase in the pressure in the AC-PDPs, the voltage drop due to the increase in the resistivity of the metal electrodes, and the decrease in the effective voltage due to the decrease in the surface resistivity of a MgO protective layer. The properties of other components such as the indium-tin-oxide (ITO) transparent electrode and the dielectric layer changed little in the considered temperature range (0 ~ 80 °C), and, thus, are not thought to affect the macroscopic properties of AC-PDPs with changing panel temperature.
