Abstract:
A flat display panel comprises a planar substrate as a part of a hermetically sealed envelope. Electrode end pieces connected at least to predetermined ones of the electrodes for display are fixed to the substrate. A plurality of grooves are formed in the substrate and snugly receive a predetermined portion of terminals connected to the respective end pieces and extended outwardly of the envelope for connection to an external circuit for driving the display panel. Preferably, the grooves have sloping end surfaces along which the respective terminals are partly extended.

There is disclosed an improved gaseous discharge display panel device and process of manufacturing same. A cathode electrode, and mask structures are printed and fired on a glass substrate, the electrodes being printed first. Upon completion of fabrication of the electrode and dielectric mask structures, they are assembled with like formed anode plate structure. Individual devices are then assembled with use of a frit seal incorporating spacer spheres. In forming the devices, fusion of the seal material may be done in an environment of the fill gas or the gas may be processed through a small gap left in the seal structure and, the gap is closed with a short gob of sealing glass after outgasing and gas filling are performed.
Abstract:
There is disclosed an improved gaseous discharge display device having segmented electrodes, typically cathode electrodes, shaped in the form of segments of characters to be displayed, a viewing plate carrying an opposing electrode, typically an anode electrode, there being one such anode electrode for each character position to be displayed and a seal sealing the electrodes and a gaseous medium at glow discharge pressure therein. The cathode electrodes are a sputter resistant material selected from the group consisting of silicon carbide, tungsten boride, chromium boride, molybdenum boride and molybdenum disilicide, these sputter resistant materials being in powder form deposited upon the dielectric substrate to form at least some of the electrodes and in a preferred form, the sputter resistant material is applied as a coating to conventional precious metal electrodes such as silver.
Abstract:
Apparatus for changing a dimension of the light-producing area in a display element of the type which emits light from any portion of an interface zone across which a voltage exceeding a certain threshold is established, by varying this voltage. A bias voltage source provides a potential along one side of the interface zone, which increases from one end to the other, with respect to the other side. The apparatus is particularly well suited for an electronic bar graph type indicator. Gas discharge devices such as plasma tubes, and LED's are particularly suitable types of display elements.

Abstract:
Display devices adapted to display one or more characters sideby-side in one or more rows and including several groups of display cathode segments positioned in a row, with corresponding segments in each group connected in common, an anode electrode associated with each group of the display segments, and an auxiliary electrode partially surrounding and electrically isolating each group of display segments. The cathode segments, together with an anode, can be selectively energized to display a character at any desired cathode group or position. The auxiliary electrode can be energized to inhibit electrical discharge between the display cathode segments and any other than the associated anode.
