Abstract:
The display panel includes a plurality of character positions and is of a sandwich construction and includes a base plate on which a plurality of groups of cathodes and their conductors are formed. Each group of cathodes can 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 and shaped and positioned to provide proper operation with its group of cathodes but to minimize cross-talk between groups of cathodes and between adjacent character positions.
Abstract:
A display panel includes a slotted structure for providing gas communication paths, the slotted structure comprising insulating plates having a plurality of parallel slots which extend completely through one of the plates, and along substantially the entire length thereof, electrodes are disposed between the plates and above and below the plates to form two layers of cells.
Abstract:
A display panel comprises a plurality of insulating plates, between which several arrays of electrodes are secured. The panel is assembled by first preparing at least one subassembly comprising an array of electrodes secured to an insulating plate and then sealing the various parts together.
Abstract:
A display panel including first and second layers of gas-filled cells with cathodes in common between the layers and with separate anodes associated with each layer. Tiny apertures in the cathodes interconnect respective cells in each layer. Doublelayered cathodes are used to prevent spurious transfer of ionized gas (cathode glow) from the cells in one layer to the respective cells in the other layer.
Abstract:
A cold cathode gaseous display device including a plurality of cathode plates having spaced-apart cathode tabs, each adapted to exhibit cathode glow. The cathode plates are identical and are positioned so that each tab of one is physically associated with the corresponding tabs of the others. Corresponding cathode tabs of each plate are thus physically arranged in a group. The device also includes an anode electrode for each group of cathode tabs, with each anode electrode including a separate anode tab for each cathode tab in the associated group.
Abstract:
A method of making a gas discharge display device comprising assembling the component parts of the device and providing a tabulation through which the device can be filled with the desired gas. A capsule containing an antisputtering agent such as mercury is mounted within the tabulation, along with suitable means by which it may be heated. The device is suitably baked out and otherwise preliminarily processed; the desired gas is introduced; and the tubulation is sealed off with the capsule remaining therein. After any other processing steps are carried out as required, the material is freed from the capsule, and, with the entire assembly heated to a suitable temperature to cause the anitsputtering agent to enter the working area of the device, the tubulation is sealed off at an area close to the device itself and with the capsule within the portion of the tubulation which is removed.
