Abstract:
A method of fabricating a display panel on a substrate material of soda-lime float glass. A dielectric layer composed of a mixture of lead, silicon and aluminum is deposited on the substrate to a thickness of from 25 to 150 microns. A masking pattern is defined on the surface of the dielectric layer where plasma display cavities are to be formed. Openings are etched in the dielectric layer with fluoboric acid to geometries no larger than approximately 0.15 mm wide by 0.15 mm thick at regions defined by the masking pattern, the openings extending to the major surface of the substrate and forming a plasma display cavity. A cover is provided over the cavity to form an enclosed envelope containing a noble gas. A phosphor is provided in the plasma display cavity together with electrodes adjacent to the cavity for ionizing the gas and exciting the phosphor.
Abstract:
A display panel comprising a gas-filled envelope containing an array of rows and columns of D.C. scan/address cells, each scan/address cell including a volume of gas and an anode electrode and a cathode electrode, and an array of rows and columns of display cells, each display cell including a volume of gas and two electrodes, one electrode being in the form of an apertured plate whose apertures are the display cells, the other electrode being an apertured electrode whose apertures are considerably smaller than the apertures in the one electrode and so numerous that the greater portion of the area of the other electrode is light-transmissive whereby the human eye does not see the solid portions of the other electrode which define the apertures therein.
