New Penning Gas (Deuterium) for the Improvement of Luminance and Luminous Efficiency in Alternative Current-Plasma Display Panels

Abstract

The effects of addition of deuterium (D2) to conventional gases [Ne (92%)–Xe (8%) and He (70%)–Ne (27%)–Xe (3%)] on discharge characteristics were investigated in this work, with the aim of improving luminance and luminous efficiency as well as achieving low sustain voltage. When the gas-inlet amounts of D2 added to Ne–Xe or He–Ne–Xe gas-inlet mixture were varied from 0 to 0.1%, we measured the sustain voltage, the luminance, the luminous efficiency and the wall charge corresponding to each gas-inlet. The addition of extremely small gas-inlet amounts of D2 increased the number of electrons, which improves the Xe* density [Xe*(1s4)→Xe+hν(147 nm)]. As a result, luminance and luminous efficiency increased while the sustain voltage decreased.
