The Luminous Efficiency Improvement of Color AC Plasma Display Panel by adding Ar Gas

In this study, we analyzed the luminous efficiencies of Ne-Xe-Ar and He-Ne-Xe-Ar mixing gas in compared with those of Ne-Xe and He-Ne-Xe mixing gas to improve luminous efficiency by adding a small amount of Ar gas. At the Xe 4%, the brightness of Ne-Xe and He-Ne-Xe mixing gas is higher than others. As the Xe % increases, power consumption decreases. Thus, in the Ne-Xe and He-Ne-Xe mixing gas of Xe 4%, we obtained maxium luminous efficiency. The Ar concentration is varied from 0.1% to 0.7% in this study. The luminous efficiency of the Ne-Xe(4%) mixing gas is improved to 1.16 and 1.13 lm/W by adding an Ar concentration of 0.4% and 0.5%, respectively. The luminous efficiency of the He-Ne-Xe(4%) (He : Ne = 7 : 3) mixing gas is considerably improved by adding an Ar concentration of above 0.3%. The maximum luminous efficiency of this mixing gas is 1.38 lm/W at the condition of adding an Ar concentration of 0.5%.
