FLUORESZENZ-GASENTLADUNGSANZEIGEVORRICHTUNG.

摘要

A fluorescent gas-discharge display panel, in which a fluorescent material (8) is excited by a gas discharge therein, contains a gas mixture of neon, argon and xenon as the discharge gas (9). Typically, the argon gas content is more than 5% by partial pressure, and the xenon gas less than 10%. The argon gas content contributes to produce a pure and high peak of green light spectrum and to reduce the orange light spectrum produced by the discharge of the neon gas. Other characteristics, such as operation voltages, brightness, luminous efficacy, and operation life, are kept satisfactory.
