Abstract:Influence of the noble gas mixture composition on the performance of a plasma display panel Influence of gas mixture ratio on the luminous efficiency in surface discharge alternating current plasma display panelsWe propose the optimal mixing ratio of Ar or Kr in Ne ͑96%͒-Xe ͑4%͒ and He ͑70%͒-Ne ͑27%͒-Xe ͑3%͒ to improve the luminance and luminous efficiency for alternating current plasma display panels. To verify the improvements, we measured the voltage, current, and luminance experimentally. We analyzed the l… Show more
A volume-averaged, zero-dimensional numerical simulator for ac discharge of plasma display panel (PDP) is developed. The vacuum-ultraviolet photons such as 147 and 173nm are treated as particles that cannot be stored. The surface charge on the dielectric layer is introduced in this study. Solving particle continuity and electron energy balance equations simultaneously, the characteristics of ac-discharge phenomena, such as the temporal evolution of surface charge, electric field, and particle densities, are analyzed. This numerical simulation result shows that the increment of the percentage of xenon atoms in a neon-xenon mixture of PDP improves the luminous efficiency of the ac-discharge gas by raising the intensity of 173nm vacuum-ultraviolet photons from xenon excimers.
