Abstract:
A plasma display, comprising:a bulb having an outer bulb portion and an inner bulb portion hermetically connected with said outer bulb portion thereby creating a hermetically sealed chamber, said inner bulb portion having an inner surface and an outer surface facing said chamber, said bulb further having a conductive coating on said inner surface of said inner portion;air control means for selectively creating a vacuum and infusing a discharging gas into said chamber, said discharging gas selected from the group comprised of: the combination of: 93-96% Kr, 2%-5% Xe, 1%-4% He, 1%-3% N, and 50-500 ppm O; and the combination of: 93%-96% Ne, 2%-5% Xe, 1%-4% He, 1%-3% N, and 50-500 ppm O; andmeans for selectively providing electricity of varying voltage and frequency to said conductive coating of said inner surface of said inner bulb portion,wherein supplying voltage to said conductive coating causes visible arcs of plasma between said inner bulb portion to said outer bulb portion and varying the voltage of the electricity changes the visual appearance of said plasma arcs.
