    • PROBLEM TO BE SOLVED: To provide an image display device of low-power consumption by reducing a current flowing through a spacer in the image display device of an FED system. SOLUTION: The image display device is composed of a cathode substrate provided with a plurality of electron emission elements emitting electrons, an anode substrate disposed opposite the cathode substrate and having a phosphor and metal back, the spacer supporting the cathode substrate and the anode substrate, a high-voltage control circuit controlling a high-voltage at both ends of the spacer, and a video signal detection circuit detecting the feature of the input video signal. The feature of the video signal input in the video signal detection circuit, for example, one or more of an average or maximum amplitude or a horizontal or vertical synchronization signal are detected. The current flowing through the spacer is reduced by lowering the high-voltage applied to both the ends of the spacer when the detection result is a prescribed condition. COPYRIGHT: (C)2007,JPO&INPIT

    • PROBLEM TO BE SOLVED: To selectively remove a stray emission (SE) source, without causing member deterioration due to sudden discharges in the manufacturing of an electron beam apparatus.
      SOLUTION: A high voltage is applied to an anode electrode 10 by a high-voltage power source 12; and a facing position thereof to the inside surface of a rear plate 2 and the distance between the rear plate 2 and the anode electrode 10 can be changed by a moving device 11. An ammeter 13 is used to measure the emission current, flowing through the rear plate 2 by SE and connected in common with an conductive member on the rear plate 2. A control device 14 reads a current value from the ammeter 13, to control the position of the anode electrode 10 by the moving device 11 and the voltage value of the high-voltage power source. An SE source is removed by using this detection device, and by using an extrapolation method to estimate the correct SE source position.
