Influences of He Contents and Panel Working Gas Pressures in Ternary Gas Mixture on Discharge Characteristics in AC Plasma Display Panel

Abstract

The discharge characteristics, particularly the address and sustain discharge characteristics, were examined relative to the He contents and panel working gas pressures under 11% Xe content in the 50-in. full HD AC-PDPs with a ternary gas mixture (Xe-He-Ne). The Xe content in this study was fixed at 11%. As the helium gas increases from 0 to 50%, the formative address delay becomes shortened by about 60 ns. In addition, the luminance are increased by about 15 cd/m2 because of enlarging the Xe2* excimer emission (823 nm) with an increase with the He gas. Also, the power consumption is reduced by about 30 W since the addition of He gas induces a reduction of cathode fall potential. The decrease in the gas pressure from 600 to 300 Torr causes a lower firing voltage, thereby resulting in reducing both the formative and statistical address delay times by about 71 ns and by about 65 ns, respectively. As a consequence, the pressure below 400 Torr and He content above 50% are the best panel factors suitable for high speed and low voltage driving of micro-discharge cells with the 50 in full HD cell size.
