Abstract:
A display panel includes a plurality of rows and columns of display cells and anode and cathode electrodes associated therewith for causing glow discharge. The panel includes auxiliary starter or reset cells for facilitating the turn-on of the display cells and several keep-alive cells, including at least one uniquely located and constructed keep-alive cell, for facilitating the operation of the reset cells.
Abstract:
A panel device includes a plurality of plates which are sealed together hermetically with an array of electrodes disposed in the seal and seated on one of the plates as a support therefor. An effective seal between the parts is made by providing a quantity of sealing material in the seal area, moving the electrodes away from and back to the plate on which they are seated to suck the sealing material under the electrodes and to seat the sealing material on adjacent parts beneath and adjacent to the electrodes, and then passing a thin blade through the sealing material between the electrodes and the support plate in the seal area, in contact with both said parts, to cause the sealing material to wet such surface, whereby a tight leak-free hermetic seal can be formed.
Abstract:
A gaseous display panel includes a top plate, a bottom plate, a center plate, and a plurality of arrays of electrodes associated therewith. The bottom plate, and the top plate if desired, are provided with slots, the center plate is provided with an array of holes, and the electrodes are arrayed to provide two layers of gas-filled glow cells. The various parts are constructed to provide optimum uniformity and thereby to achieve optimum operation with maximum economies and ease in construction.
Abstract:
The display panel comprises first and second layers of communicating gas-filled display cells. The first layer includes a first plate having grooves, with first electrodes seated in the grooves, and second flat strip electrodes supported by the plate so that the first and second electrodes and the gas in the slots between them form a first layer of cells. The second layer includes a second plate having cell apertures seated on the second electrodes, with third electrodes in the grooves of the second plate or on the top surface of the plate where an apertured plate is used, so that the second and third electrodes and the gas-filled space between them comprise the second layer of cells. Typically, in operation of the display panel, the second electrodes are connected in groups, and each group is connected to a source of operating potential. Various arrangements are described for connecting the second electrodes in such groups.
Abstract:
A display panel includes a plurality of display cells arrayed in rows and columns, with electrodes coupled to the cells in such a way that a plurality of rows of characters can be displayed, with blank spaces being provided between the rows of characters. Electrodes may be provided in these blank spaces to perform an auxiliary function such as a keep-alive function.
Abstract:
A gas-filled display panel includes a top plate, a bottom plate, an apertured center plate, and a plurality of arrays of electrodes associated therewith. The bottom plate is provided with slots for receiving an array of scanning anode electrodes; an array of scanning cathode electrodes is disposed between the bottom plate and the center plate, and an array of display anode electrodes is disposed between the center plate and the top plate. The electrodes and plates are interrelated to provide upper and lower layers of gas-filled cells. The cathode electrodes comprise metal strips which are elongated and have an array of apertures disposed along their lengths, each aperture providing communication between a cell in the lower layer and a cell in the upper layer. The cathode strips are of sufficient thickness to provide strength and rigidity except for a thinner central portion which extends along, and is aligned with, the array of apertures therein whereby the apertures are of minimum depth.
Abstract:
The illustrated display panel includes a matrix of communicating gas-filled display cells. A first layer includes an enlarged first plate having grooves in it, with first electrodes seated in the grooves, and second electrodes supported across them. A second layer includes an apertured plate seated on the second electrodes, with third electrodes positioned on the top surface of the second plate. The first electrodes residing in the grooves in one extension of the first plate are exposed and are accessed there by connector contacts. The third electrodes are fitted at one end into grooves in another extension of the first plate. The electrodes and plates forming the device may also be aligned with reference to the grooves in the base plate.
Abstract:
A keep-alive electrode arrangement is intended for use with a display panel which includes a slotted base plate in which a first set of electrodes is seated, with a second set being seated on or in the top surface of the base plate to form an array of first gas-filled cells. An apertured insulating plate is seated on the base plate with the second electrodes therebetween, and third electrodes are seated on the top surface of the second plate. A glass cover plate completes the panel. A keep-alive electrode arrangement comprises first and second electrodes, both seated in one of the slots in the base plate suitably insulated from each other and providing a glow area which is in communication with one of the second electrodes.
Abstract:
A gas-filled display panel includes a plurality of rows and columns of display cells and associated electrodes. The panel also includes a trigger means, known as a keep-alive cell, to facilitate the turn-on of the display cells. The keep-alive cell is heat-sensitive, and it is secured in the panel by techniques which operate at room temperature.
Abstract:
A display panel includes a plurality of gas-filled cells which comprise apertures in an insulating plate, and each cell has a cathode at its lower end and an anode at its upper end, from which light exits to a viewer. The walls of the cells are made of light-reflecting material so that nonaxial light rays generated at each cathode reflect back and forth upwardly along the cell walls and exit at different angles. With light rays thus exiting at a wide range of angles, an effective wide viewing angle is presented to a viewer. The surface of the apertured plate which faces the viewer is also light-absorbent to minimize light reflection therefrom toward the viewer.
