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.

Abstract: ELECTRO-OPTICALLY MATRIX-ADDRESSED ELECTROLUMINESCENCE DISPLAY WITH MEMORY It has been discovered for the practice of this disclosure that there is a threshold for switching with light an AC coupled electroluminescence (EL) device within the .DELTA.V of the luminance-voltage hysteresis loop thereof. Practice of this disclosure provides hybrid matrix-addressing of an electroluminescence display device with memory through luminance-voltage hysteresis by "ANDING" electrical and optical signals. It has particular utility for a large aspect ratio display, e.g., a single line display, i.e., one for which there is more information content in one direction than in another direction. YO977-079
