    摘要: 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.

A plurality of surface conduction electron-emitting devices (1002) are arranged on a substrate (1001). Light emission is performed in accordance with the colors (R, G, and B) of phosphors applied to a phosphor film (1008) upon electron emission from the devices, so that an image is formed. The electron-emitting characteristics of the surface conduction electron-emitting devices (1002) are shifted in advance in correspondence with corresponding phosphor colors. Therefore, a satisfactory white balance of light emission of the R, G, and B phosphors can be obtained.

    摘要: 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). A pulse width signal (PW1 to PWn) from a pulse-width modulation circuit (7) serves to switch the mode of outputting a current (I1 to In) to a data wiring layer (Dy1 to Dyn) and the mode of fixing a data wiring layer to voltage GND.
