  • Spacer and an image-forming apparatus, and a manufacturing method thereof
    Patent number: 6153973
    Abstract: An image-forming apparatus comprises a rear plate on which an electron-emitting device is provided, a face plate having an image-forming member and arranged to be opposed to the rear plate, and a spacer provided between the face plate and the rear plate. The spacer comprises a spacer base plate and a coating layer including organic resin and carbon. At least part of the carbon is exposed from the surface of the coating layer. The image-forming apparatus displays an image with a high luminance and a high color saturation over a prolonged time.

  • Method of manufacturing electron-emitting device, electron source and image-forming apparatus
    Patent number: 6017259
    Abstract: An electron-emitting device has a pair of device electrodes formed on a substrate, an electroconductive film connecting the device electrodes and an electron-emitting region formed in the electroconductive film. The electron-emitting device is manufactured by (1) applying an ink containing the material for producing the electroconductive film to a predetermined position of the substrate in the form of one or more than one drops by means an ink-jet apparatus, (2) drying and/or baking the applied drop(s) to turn the drop(s) into an electroconductive thin film and (3) applying a voltage to the pair of device electrodes to flow an electric current through the electroconductive film and produce an electron-emitting region. Steps (1) and (2) are so conducted that the electroconductive film formed by steps (1) and (2) have a latent image apt to produce an electron-emitting region by the Joule's heat generated by step (3).
