Thin-film planar edge-emitter field emission flat panel display

A field-emission-display comprising:

• a cathode having a first conductive film having a low electron affinity and a second conductive film disposed on the first conductive film, the second conductive film enhancing the conductivity of the first conductive film, the first conductive film having an edge which is operative for emitting an electron beam;
• and
• an anode spaced from said cathode, the anode having a third conductive film and a layer of light emitting material disposed over the third conductive film, the layer of light emitting material emitting light when activated by an electron beam generated by the edge of the first conductive film of the cathode, said anode further includes a layer of conductive material disposed between the third conductive film and the layer of light emitting material, the layer of conductive material positioning the layer of light emitting material closer to the cathode;
• the cathode and anode forming an active pixel structure.

A pixel structure suitable for low voltage operation in a field-emission-display, the pixel structure having substantially no cross-talk, the pixel structure comprising:

• a cathode having a first conductive film having a low electron affinity and a second conductive film disposed on the first conductive film, the second conductive film enhancing the conductivity of the first conductive film, the first conductive film having an edge which is operative for emitting an electron beam;
• and
• an anode spaced from said cathode, the anode having a third conductive film and a layer of light emitting material disposed over the third conductive film, the layer of light emitting material emitting light when activated by an electron beam generated by the edge of the first conductive film of the cathode;
• a substrate of electrically insulative material, wherein the substrate includes first and second parallel planes, the cathode disposed on the first plane and the anode disposed on the second plane, the cathode and anode disposed without overlapping one another and the distance between the first and third conductive films being at least 2-4 microns.
