Abstract:
The display panel comprises first and second layers of communicating gas-filled cells having a common electrode system between them which comprises first electrodes supported in an insulating matrix. Second electrodes are disposed above the first electrodes and insulated therefrom, and third electrodes are disposed below the first electrodes and insulated therefrom.
Abstract:
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.
Abstract:
A display panel utilizing an array of gas-filled cells in an insulator sheet the cells being arranged in upper and lower layers of aligned cells with pairs of upper and lower cells separated by a common cathode electrode. The cathode electrodes are parallel strips corrugated in a series of rectangular waves, each flat elevated portion of a corrugation being embedded in an aperture of the insulator sheet and dividing the aperture into upper and lower cells interconnected by a tiny hole in the cathode. The parallel sides of a corrugation form walls of a cell. A single corrugated electrode thus forms a column of upper and lower cells across the panel. Pairs of associated anodes cross opposite ends of the apertures perpendicular to the common cathodes preferably in slots in the insulator to form rows of cells. Pairs of baseplates are sealed to the insulator sheet to form an hermetic unit.
Abstract:
A display panel includes a plurality of layers of gas-filled glow cells and a plurality of arrays of electrodes. One layer of cells is scanned once for each picture to be stored and displayed, and another layer is used to display the glow or picture with memory.
Abstract:
A display panel having a plurality of gas-filled cells arrayed in rows and columns and having gas communication paths between adjacent cells formed by properly overlaying and offsetting plates having identical openings so that portions of corresponding openings form the cells and other portions form the gas communication paths between cells.
Abstract:
A display panel which includes a plurality of groups of cathode glow segments disposed side by side for displaying side by side characters. Each group of cathode glow segments is formed of a single large-area glow cathode which is coated over its surface except at selected areas or segments. In operation, different combinations of these uncoated areas or segments are energized, and thus caused to glow, to display different characters. The cathode segments are energized by anodes which comprise conductive strips that pass along the length of the cathode segment groups but are suitably coated or masked to provide the required communication only with selected ones of the cathode segments.
