Abstract
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.
