ABSTRACT:
A blue color AC gas discharge display panel is obtained by the room-temperature Hg vapor seeding of high pressure Ar gas as the luminous gas mixture. Typically, the panel uses room-temperature Hg (approximately 3m Torr) in several hundred Torr of argon. Generally, good resolution is achieved in standard AC panels in at least 300 Torr. The upper limit is nominally one atmosphere. This gives an Hg seeding of less than 0.001% of the total gas pressure. Thus, direct electron excitation of Hg atoms is negligible and the discharge condition involves only the excitation of argon atoms by the electrons.
