  • Patent number: 6590320
    Abstract: A field-emission-display (FED) having a pixel structure which operates at small anode voltages, and thus, provides the FED with an increased life-time. The pixel structure of the FED includes an edge emitting cathode and an anode spaced from the cathode. The cathode has a first conductive film with a low electron affinity, such as alpha-carbon and a second conductive film disposed on the first conductive film. The first conductive film has an edge which is operative for emitting an electron beam. The anode has a third conductive film and a layer of light emitting material disposed over the third conductive film. Both the cathode and the anode are fabricated on a single glass substrate, which provides simple and reliable mass production technology compatible with planar silicon batch fabrication technology.
