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 in its top surface, and vertical slots in its end edges, and an anode wire is disposed in each of the longitudinal slots in the base plate, and they are recessed in the edge slots and terminate at pins secured to the bottom surface of the base plate. Cathode electrodes are provided on the base plate, and they also terminate at pins secured to the bottom surface of the base plate. With this arrangement, panels can be butted end to end to provide a longer line of characters than one panel alone.
