Abstract: A method of fabricating an emitter of a field emission display. A mixture of metal and silver paste with glass material is screen printed on a substrate as a silver electrode. The metal is selected from a hard solder alloy such as Al/Si alloy containing tin, zinc, aluminum or other low melting point metal. Alternatively, the metal and the silver paste with the glass material are separately screen printed on the substrate. The metal is selected from tin, zinc, aluminum, or an alloy with a low melting point such as aluminum/silicon alloy. A carbon nano-tube layer is formed on the silver electrode by coating the carbon nano-tube material with the electric arc. Alternately a catalyst layer can be formed on the silver electrode prior to the formation of the carbon nano-tube layer. A metal layer such as nickel and copper is formed on the carbon nano-tube layer to prevent the carbon nano-tube layer from absorbing gas.

Abstract: Apparatus and method are provided for using a multi-element field emission cathode in a color cathode ray tube. The field emission cathode may have from four to ten field emission arrays linearly arranged. The arrays are preferably formed from carbon-based material. An electron gun assembly focuses electron beams from each array on to a phosphor stripe or dot on the screen of the cathode ray tube. Deflection apparatus moves the beam from each field emission array according to clock signals. Clock signals also turn on or turn off voltage to contacts controlling electron current from the array. Values of voltage applied, determined by a video signal, determine the intensity of electron current from each array, which controls the intensity of the light emitted by each color stripe or dot of phosphor on the phosphor screen.

Abstract: An electron emitter includes a coating layer of a mixture of carbon nanotubes and alkali-earth metal oxides on an electrically conducting structure. The preferred carbon nanotubes are those having a diameter less than about 200 nm. A substantial portion of electron emission is liberated from the carbon nanotubes, thus lessening the requirement on the alkali-earth oxides. Such an electron emitter is advantageously used in gas discharge devices to increase the energy efficiency thereof.
