  • Electronic fluorescent display system
    Patent number: 5621284
    Abstract: A cathodoluminescent device employs elongated grid electrodes such as small gauge wires for addressing and controlling the brightness of the display, thereby increasing the osmotic coefficient of the grid electrodes. End portions of the cathode filaments are bent into springs to reduce cold terminal effects. The edges of the face plate of the device are curved to reduce the visual effects of mosaic slots. The display may be operated at low anode voltage with increased luminescence so that full screen scanning is possible. Different sections of narrow strips forming a staggered structure strengthens the integrity of the device and reduces dark areas in the display.
    Type: Grant
    Filed: March 10, 1995
    Date of Patent: April 15, 1997
    Assignees: Pixtech, Inc., Hangzhou University
    Inventors: Ge Shichao, Victor Lam, Huang Xi, Jin Weicheng, Ruan Shiping
