Abstract
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.
