  • Publication number: 20020015026
    Abstract: A vacuum cathodoluminescent display device, also called a vacuum fluorescent display, with filamentary cathodes parallel to control gate wires and a matrix drive system utilizing anode based phosphor stripes adjacent and perpendicular to the control electrode gate wires, is introduced with tunable control electrode gate wire pairs via an unbalanced voltage drive which optimizes to the maximum the design and actual performance of the display device. Specifically, the tunable unbalanced control electrode voltage drive leads to the following decisive advantages over the prior art: 1) Increasing the efficiency of emission of electrons from the cathode 2) Efficiently bunching, guiding and focusing the electron stream emitted by the cathode into the activated gate and on to the assigned phosphor pixels 3) Avoiding electron interception and heating of active and inactive gate wires.

  • Publication number: 20010015616
    Abstract: In flat panel displays wherein thermionic electrons are focused to a narrow beam by means of an anode or gating grids, such grids structures are subjected to temperature deformation and vibratory stress. In high resolution displays individual grid structures are placed in close proximity to similar structures, often less than 0.0265 inch apart. Failure to accommodate physical deformation due to wide variations in temperature and or physical stress caused by shock and vibration will cause the grid wires to short circuit and the display to fail. The invention operates to maintain the relative separation of the individual grid structures within a range of temperatures, shock, and vibration.

  • Patent number: 5831397
    Abstract: A deflecting apparatus for a flat-panel display having an evacuated display housing and a display screen. The display has phosphor stripes or dots for generating visible radiation when bombarded with electrons when accelerating voltage V.sub.1 is applied to stripes. The invention provides for an elongate electron source positioned in the back of the evacuated display housing for emitting electrons which are guided to the display screen through an anode grid or an electron gating grid located before the display screen. The deflecting apparatus for rendering the beam of electrons emitted from the elongate electron source uniform has a deflecting element or unit which is positioned at the back of the display housing and produces a spatially parabolic potential under the influence of steering potential V.sub.4. This spatially parabolic potential forces the electrons moving in the direction of the anode grid or gating grid to form a uniform beam.

  • Patent number: 5590182
    Abstract: A control device may be connected in series or in parallel to a telephone for restricting or routing calls made from the telephone to take advantage of low cost carriers for intra-LATA calls. The serial or parallel connection of the telephone can be detected as well. The device may be programmed for routing depending on the geographical location of the telephone. The central receiving office of the local phone company can be prevented from routing the call by the use of interfering tones.
