  • Patent number: 7855500
    Abstract: An electron emission display that can mitigate or prevent problems of an arc discharge and a wire disconnection due to increases in resistance at portions where a sealing member contacts electrodes includes: an electron emission device on which upper surfaces of electrodes are exposed, a front panel that is disposed in front of the electron emission device, the front panel being of a phosphor material, and a sealing member that seals a space formed by the electron emission device and the front panel by being disposed on the edges of the space in contact with the electrodes. The electrodes are formed on an entire surface of the electron emission device with a narrow width at an end portion of the electron emission device where the electrodes are connected to an external power source, and the sealing member contacts the electrodes closer to the space than end portions of the electrodes where the width of the electrodes is narrowed.

  • Patent number: 7812511
    Abstract: A field emission illumination device includes a sealed tubular body, an anode layer, a fluorescence layer and an electron emitting cathode electrode. The sealed tubular body has a light-permeable portion and the anode is formed on an inner surface of the light-permeable portion of the tubular body. The fluorescence layer is formed on the anode layer. The electron emitting cathode is positioned in the tubular body and includes at least one carbon nanotube yarn. In the illuminating process the energy in the field emission illumination device only undergoes transformation from electric energy to luminous energy, so the efficiency of the energy transformation is increased.

  • Patent number: 7733017
    Abstract: An electroluminescent apparatus utilizes a replaceable electroluminescent element which is compressed between two electrodes that are positioned within a resealable housing which may be opened and closed so that a used electroluminescent element may be removed from between the electrodes and replaced at the end of its usable lifetime. The housing has front and rear panels associated with the respective electrodes, at least one of the panels being transparent. The apparatus may include an inflatable compressing structure, an alignment structure within the housing for alignment of the electroluminescent sheet, or transparent electrodes, and various drivers may be used allowing for monochrome or color displays. The housing may have an envelope configuration, or the electroluminescent element can have a configuration of a roll of sequential electroluminescent sheets or a tiled structure allowing for larger electroluminescent displays, within the scope of the present invention.
