Title:
GAS DISCHARGE PANEL AND GAS LIGHT-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/1999/009578
Kind Code:
A1
Abstract:
A gas discharge panel improved in the efficiency of converting discharge energy into visible light, panel brightness, and color purity. A gaseous medium is filled in the gas discharge panel under a pressure of 800 to 4000 Torr, which is higher than that of the prior art. Instead of the conventional gaseous composition, furthermore, the gaseous medium to be filled is a mixture of rare gases including helium, neon, xenon and argon. Desirably, the content of xenon is not larger than 5% by volume, the content of argon is not larger than 0.5% by volume and the content of helium is smaller than 55% by volume, thus making it possible to improve the light-emitting efficiency and to lower the discharge voltage. When a display electrode and an address electrode are laminated on the surface of either a front cover plate or a back plate via a dielectric layer, the addressing can be effected at a relatively low voltage even when a sealing pressure is high.
