Abstract:
A display device adapted to display one or more characters side by side in a row and including an insulating support plate, on the top surface of which are formed a plurality of groups of conductive members, each group being adapted to be energized to display a character. The device includes various configurations of anode electrodes, shielding electrodes, and interconnections of common characters in each group to provide manufacturing economies.
Abstract:
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 anaodes and cathodes causes selected cells to glow and display a character.
Abstract:
The drawing discloses a tube which includes a large number of cathode rods arrayed in rows and enclosed in cavities in a stack of plates including, from bottom to top, a metal focusing plate for controlling the location of glow on the cathode rods, an opaque insulating disk, an opaque disk shaped to trap cathode sputtering and to prevent the spread of cathode glow from one cathode aperture to an adjacent aperture, and an anode plate.
Abstract:
The display panel is gas-filled and includes a base plate on which a plurality of groups of cathodes and their conductors are formed, each group of cathodes being operable to display a character. The panel also includes a face plate, spaced from the base plate, and carrying transparent conductive anodes, each associated with one group of cathodes. The panel includes a tubulation secured to the base plate through which gas and mercury vapor are introduced into the panel through a hole in the panel base plate. A mass of fibrous material is disposed in the tubulation adjacent to the hole in the base plate to prevent globules of free mercury from entering the panel and, at the same time, permitting mercury vapor to enter the panel.
