ABSTRACT:
A gas discharge display tube, which has a rear tube wall with parallel extending cathode strips mounted thereon characterized by the cathode strips being mounted by each strip having a pair of spring plates slidably received on pins which are fused into the rear wall of the tube. Preferably, each of the strips has a box-like cross section for slidably receiving the spring plates so that the strip can be shifted along its length on the pins. In addition, the pins for adjacent strips are offset from each other so that the pins are aligned in two rows at each end of each of the cathode strips.
