BUTTABLE DISPLAY PANEL Abstract of the Disclosure The display panel is a dot matrix panel and comprises relatively large gas-filled cells which are arrayed in rows and columns and are adapted to be energized in different combinations to display characters. The cells are formed by strip-like column cathode electrodes having localized active areas formed therein to comprise the active cathodes, the localized areas of all of the cathodes being arrayed in rows and columns. The cathode electrodes and their localized areas are shaped and spaced apart so that, in the final panel, a suitable seal area is provided and panels can be butted together. An insulated plate having horizontal apertures, each aligned with a row of cells, overlays the cathodes, and a face plate is seated on the insulating plate carrying horizontal anodes formed with localized active areas arrayed in rows and columns, each aligned with one of the cathode areas and each carrying a quantity of a phosphor material. Electrical energization of selected anodes and cathodes causes selected cells to glow and display a character.
