ABSTRACT:
A display panel comprises a gas-filled envelope made up of a base plate and a face plate sealed together hermetically. The base plate is provided with a plurality of parallel, longitudinal slots, and an anode wire is disposed in each of the slots in the base plate. An array of identical metal strip electrodes are provided on the base plate at an angle to the anode wires to define operative gas cells therewith. The first strip electrode is operated as a keep-alive anode with respect to two auxiliary electrodes seated in slots in the base plate, the second strip electrode is operated as a reset cathode, and the other strip electrodes are operated as the scan/display cathodes for the panel.
