  • Gas discharge display panel having novel cathode assembly
    Patent number: 4766345
    Abstract: A cold cathode gas discharge display panel comprising a gas-filled envelope including a glass base plate and glass face plate. An array of linear electrodes are provided on the base plate with some of the cathodes having adjacent ends. The usual masking layer of insulating material is provided on the base plate to outline the cathodes but this insulating layer does not cover the adjacent ends of the cathodes so that these ends are operatively disposed close together. Thus an improved glow blending of adjacent cathode ends is achieved.
