Analysis of the Discharge Characteristics for Kr Gas Mixtures in an ac Plasma Display Panel

We investigated the discharge characteristics of a Kr gas mixture in an ac plasma display panel through two-dimensional numerical simulations. In a Ne-Kr gas mixture, the VUV output and the efficacy increase with higher Kr content due to an increase in the VUV source. In order to analyze the effect of Kr content on the luminous characteristics for various gas mixtures, we compared the results for Ne-Kr, Ne-Kr-Xe and Ne-Xe mixtures. As the Kr content was decreased and the Xe content increased, the VUV generation efficacy increased because the lower energy level of the Xe excited state caused the generation of excited species to be more effective than that of Kr gas.
