Abstract:
1. A large area plasma display comprising: a plurality of sealed plasma pixel panels each having two opposing substrates of which one substrate contains an address electrode, coated with a thin dielectric layer followed by a reflective dielectric layer and further followed by a phosphor layer, the other substrate contains two coplanar plasma sustain electrodes with a dielectric barrier between the plasma sustain electrodes, the plasma sustain electrodes and the dielectric barrier being coated with a thin dielectric layer followed by an electron secondary emission layer; said address electrode and plasma sustain electrodes being located on said substrates so as to be orthogonal to each other in opposition to create a plasma pixel; said opposing substrates being hermetically sealed with a frit glass to create a space between the said substrates; said space between the said substrates being filled with an inert gas and mercury; said sustain electrodes, dielectric barrier and address electrodes, in combination with a suitable voltage, generating an increased path length of plasma that generates increased ultra-violet rays which excites the phosphor resulting in enhanced visible light output from plasma pixels; said plasma pixel assembly incorporating integrated lead-in from interior of pixels to exterior pins for address electrodes and sustain electrodes; said plasma pixel assembly further assembled in large rigid plastic frames in plurality in a desired color format to form a large area plasma display; means for externally connecting and applying electrical signal to the said large area plasma display comprising plurality of said plasma pixels, to generate information on the said large area plasma display, through selective visible light emission from the said plasma pixels; said large area plasma display comprising tiles of plasma pixels containing coplanar sustain electrodes and address electrodes; said coplanar sustain electrodes intervened by dielectric barriers said coplanar sustain electrodes have a length in the range of 6 mm to 300 mm and a linear distance between them in the range of 6 mm to 300 mm, excluding the curved length of dielectric barrier between them.
