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 outgasingand gas filling are performed.
摘要:
A display panel comprising a plurality of gas-filled cells, each having a pair of energizing electrodes and adapted to be energized in groups to display characters. The panel also includes a plurality of cells which are adapted to be energized so that they glow continuously and facilitate the turning on of the groups of cells which are used to display a character. These auxiliary energizing cells are hidden from view so that they perform their function without being seen and without interfering with viewing of the primary characters.

There is disclosed an improved gaseous discharge display panel device and process of manufacturing same. A large number of cathode substrate electrode and mask structures are printed and fired on a single glass sheet, the electrodes being printed first and dried/cured at a higher temperature than subsequently applied mask and electrical crossovers, which are cured at lower temperatures. Upon completion of fabrication of the electrode and dielectric mask structures and crossover connections, the glass plate is simply scored and separated to provide individual back substrate and electrode mask structures which are then assembled with a like formed anode plate structure. Individual devices are then assembled with use of a seal rod preformed to have a gap in the seal structure and a laser facturable mercury dispensing giver. In forming the devices, the gas is processed through the small gap left in the seal structure and, the gap is closed with a short sealing rod through and about which outgasing and gas filling are formed during the final gasing step. Batch processing of devices in the range of 1000 - 5000 in a relatively short period of time.

摘要:
There is disclosed an improved gas discharge display panel device and process of manufacturing same of the type wherein non-conductive thin glass support substrates for anode and cathode electrodes are joined together by a sealant in a spaced-apart assembly. Printed conductors connected to the anode and cathode electrodes extend through the seal area on the respective anode and cathode substrates, which conductors are dielectric coated extensions of the conductive material constituting the electrode. A conductive silver epoxy is extruded between the plates at each point where a conductor passes through the seal and a solid metallic conductor element is inserted in the conductive silver epoxy at each place on anode or cathode lead exits from the seal area. Thereafter, the silver conductive epoxy is cured to form a conductive adhesive bonding of the metal inserts in place and making very low resistance positive connections between each of the conductors extending through the seal area to external circuitry for the device.In another embodiment, the electrical conductors which lead through the seal to the anode electrodes are coupled to contact pads on the cathode electrode at a region disposed to the rear of the edge of the anode substrate, the cathode substrate extending beyond the edge of the cathode substrate and carrying the contact pads thereon. This permits the edge of the panel to be universally adaptable to inserted conductors as well as to adapt itself to edge connectors as in conventional printed circuit boards.

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.
