  • Patent number: 6445367
    Abstract: A method and apparatus for driving an electron source in which a high-quality image display is presented by correcting a non-uniform effective current distribution caused in cold cathode elements by leakage current. A digital video signal enters a shift register where a serial-to-parallel conversion is made for each line of an image based upon a shift clock signal. One line of the image data that has been subjected to the serial-to-parallel conversion is latched in a latch circuit and then applied to a voltage modulating circuit. The latter voltage-modulates the input data and sends the modulated signal to a voltage/current converting circuit. The latter converts the voltage quantity to a current quantity, which is applied to each of the cold cathode elements of a display panel through respective column terminals. A voltage V1 is applied to the selected row wire, and a voltage V2 (V2≠V1) is applied to all other row wires, for controlling the leakage current.

  • Patent number: 6169528
    Abstract: In order to prevent voltage drops across the wiring resistances in a multi-electron source having a plurality of electron emitters wired in the form of a matrix through a plurality of data wiring layers and a plurality of scanning wiring layers, a constant current signal is output to each data wiring layer. At this time, each non-selected data wiring layer tends to be set at a high impedance and vary in potential, resulting in an abnormal turn-on operation or an electron orbit shift. A driving circuit for solving this problem is provided. A switch for switching a constant current output unit for outputting a constant current regardless of the impedance of a signal output destination, and a constant voltage output unit for outputting a constant voltage regardless of the impedance of a signal output destination is connected to each data wiring layer. For example, a constant-current circuit (17) as a current output unit always outputs the same current (I1 to In) to a switch (30).
