    Abstract: In an electronic device such as a fluorescent display tube which comprises an evacuated envelope, a plurality of cathode electrodes and an anode electrode, auxiliary electrodes are arranged between the cathode electrodes and the anode electrode. Each auxiliary electrode is impressed with AC potential superposed on DC potential and acts to disperse the electron flux emitted by the cathode electrodes in the lateral direction thus uniformly distributing the electron flux on the anode electrode.

    Abstract: A vacuum fluorescent display is disclosed having a grid plate substantially coplanar with the anode and which is controllable with conventional metal oxide semiconductor devices. Each digit of the display includes a segmented anode structure substantially surrounded by a control electrode or grid plate. At least one cathode is disposed adjacent the anode segments and control electrode such that the distance between the cathode and the control electrode is less than the distance between the cathode and any of the anode segments. Utilizing such a structure, a voltage on the order of about -5 volts on the control electrode is effective to cut off luminescence from any of the anode segments of that digit.

    Abstract: The present invention relates to a field emission lighting arrangement, comprising an anode and a cathode, where the shape of the cathode is selected based on the shape of a evacuated envelope in which the anode and cathode is provided. The inventive shape of cathode allows for an improved uniformity of an electric field provided between the anode and cathode during operation of the field emission lighting arrangement. The invention also relates to a corresponding method for selecting a shape of such a cathode.
