A study of a new Penning gas for improving the luminance and luminous efficiency in ac-PDPs

In order to improve the luminance efficiency and the luminance and to achieve low firing voltages and sustain voltages, we studied the effect of adding a small amount of D2 (deuterium) to conventional gases [Ne-Xe (8 %)]. We measured the firing voltage, the sustain voltage, the luminance, and the luminous efficiency for various amounts of D2, added to Ne-Xe gas. The addition of an extremely small amount of D2 increased the number of electrons which improved the Xe* density (147 nm) and the Xe*2 density (173 nm). As a result, the luminance and the luminous efficiency increased, and the firing voltage and the sustain voltage decreased.
