Abstract:
An improved gaseous discharge display device is disclosed for providing a multicolor capability with nominal modification of existing gaseous display technology. A dielectric glass over the conductor array on the viewing side of the device is doped with discrete transition elements arranged in a predetermined configuration, such elements being adapted to generate a specific color dot when the associated site is energized by appropriate selection signals. The panel is fabricated essentially as a conventional gaseous discharge panel, and requires no substantial modification of existing addressing and control circuitry.
Abstract:
A thin glass sheet carries seats of spaced, parallel electrodes on opposite surfaces thereof and a gaseous atmosphere overlies one surface. Applying an alternating current voltage exceeding a critical value across selected electrodes of each set causes a gas discharge to take place on the surface carrying the gas at the area of selected electrode crossing with localized visible light output.
Abstract:
A gas panel arrangement for storing, displaying and selectively shifting information from one place therein to another includes an envelope filled with an illuminable gas, a plurality of vertical conductors disposed in parallel on one side of the envelope, a plurality of horizontal conductors disposed in parallel on the opposite side of the envelope with the regions of illuminable gas in the vicinity of the coordinate intersections of the vertical and horizontal conductors defining gas cells, a writing arrangement which inserts binary information in a given portion of the envelope by igniting or not igniting the illuminable gas cells to represent binary ones and zeros, a shifting arrangement which includes a first sequence of signals repetitively supplied to the vertical conductors to shift binary information horizontally, and a sustain mechanism which supplied a second sequence of signals repetitively to given vertical conductors thereby to increase the number of ignited gas cells and accordingly increase the light intensity to render brighter letters, numbers, characters and the like which are illuminated on the face of the display device.
Abstract:
A display panel has horizontal coordinate drive lines and vertical coordinate drive lines disposed on opposite sides of a gas-filled envelope. Additional horizontal lines disposed between the horizontal coordinate drive lines and additional vertical lines disposed between the vertical coordinate drive lines may be left unconnected or floating, or they may be connected to a common potential. The additional horizontal lines and the additional vertical lines constitute a grid network which electrostatically shields each gas cell from all remaining gas cells defined by the coordinate intersections of the vertical and horizontal coordinate drive lines.
