Plasma display panel with Ne+N/sub 2/ gas-mixture discharges

The discharge characteristics of Ne+N/sub 2/ gas-mixtures were investigated for possible use in an AC Plasma Display Panel (PDP). The firing voltage increased with an increase in the N/sub 2/ concentration. When using a near ultra violet excited phosphor, (Ba,Sr)/sub 2/ SiO/sub 4/:Eu, the luminous efficiency of Ne+10% N/sub 2/ gas-mixture discharges under 400 torr was about 20% better than when using the conventional phosphor. The UV intensity emitted from the gas discharges was found to increase with an increased N/sub 2/ concentration. Furthermore, the UV efficiency increased with an increase in the N/sub 2/ partial pressure at a low N/sub 2/ concentration, yet became saturated at a high N/sub 2/ concentration.
