  • Fluorescent display tube having provision for preventing short-circuit therein, and method of manufacturing the same
    Patent number: 7132784
    Abstract: A fluorescent display tube including: (a) a substrate having a display surface; (b) anodes formed on the display surface of the substrate, and spaced apart each other; (c) cathodes capable of generating electrons; (d) fluorescent layers each of which is fixed to a corresponding one of the anodes; (e) a rib formed on the display surface of the substrate so as to surround a periphery of each of the fluorescent layers; and (f) a control electrode fixed to an upper end face of the rib, and consisting of a plurality of sections which are spaced apart each other; wherein the fluorescent layers are selectively activated by the control electrode, so as to be struck by the electrons generated by the cathodes, for emitting light, wherein the rib includes continuous wall portions continuously extending along respective boundaries each of which is located between a corresponding pair of the anodes which are adjacent to each other, such that each pair of the anodes are electrically insulated from each other, and wherein t

  • Fluorescent display tube wherein grid electrodes are formed on ribs contacting fluorescent segments, and process of manufacturing the display tube
    Patent number: 5643034
    Abstract: A fluorescent display tube including a substrate, a plurality of anodes formed on the substrate, fluorescent layers formed on the respective anodes, cathodes located above the fluorescent layers to generate electrons which strike the fluorescent layers, ribs formed of an electrically insulating material on the substrate so as to surround at least a portion of a periphery of each of the anodes and having a larger height from the substrate than the fluorescent layers, and grid electrodes formed on the respective ribs to control activation of the fluorescent layers. Each rib consists of a plurality of layers laminated by screen printing using a paste which includes the electrically insulating material.
