A pixel structure and an edge-emitter field-emission display device having a first substrate or backplate including a cathode disposed thereon and a second substrate or faceplate including an anode disposed thereon, wherein the anode on the second substrate or faceplate has a light emitting film. The cathode may define a first bus of an X-Y bus array and the anode may define a second bus of the X-Y bus array. Alternatively, the first substrate may further include a control gate disposed thereon, wherein the cathode defines a first bus of an X-Y bus array and the control gate defines a second bus of the X-Y bus array.

Pixel structure for an edge-emitter field-emission display

A Reflective Field Emission Display (FED) pixel element and system employing same are disclosed. In the FED system disclosed, each pixel element is composed of at least one emitter that is operable to emit electrons and at least one reflector that is operable to attract and reflect the emitted electrons onto a transparent anode layer that oppositely positioned with respect to the emitter and reflector and is operable to attract the reflected electrons. In one aspect of the invention, the emitter layer is shaped to bound the reflector layer forming an electrical boundary that focuses the reflected electron beam onto a phosphor layer interposed between the transparent layer. In another aspect of the invention, a high voltage and a corresponding high voltage phosphor is applied to the transparent anode layer. The use of high voltage and high voltage phosphor is advantageous as it causes the reflected electrons to be drawn deeper into the phosphor layer and, hence, reduces unwanted emissions back into the vacuum of the pixel element. In still another aspect of the invention, a plurality of phosphor layers are applied to the transparent layer to produce a color display as reflected electrons are attracted to the transparent layer.

Reflective edge field-emission pixel and associated display

A Reflective Field Emission Display (FED) system using reflective field emission pixel elements is disclosed. In the FED system disclosed, each pixel elements is composed of at least one edge emitter that is operable to emit electrons and at least one reflector that is operable to first attract and then reflect the emitted electrons onto a transparent layer that is operable to attract the reflected electrons. The transparent anode layer is oppositely positioned with respect to the cathode or emitter edge. In a one aspect of the invention, a phosphor layer interposed between the transparent layer and the pixel element produces a light photon as reflected electrons are attracted to the transparent layer. In another aspect of the invention, a plurality of phosphor layers are applied to the transparent layer to produce a color display when reflected electrons are attracted to the transparent layer.

Field-emission matrix display based on electron reflections

A Reflective Field Emission Display system, components and methods for fabricating the components. In the FED system, a plurality of reflective edge emission pixel elements are arranged in a matrix of N rows and M columns, the pixel elements contain an edge emitter that is operable to emit electrons and a reflector that is operable to extract and laterally reflect emitted electrons. A collector layer, laterally disposed from said reflector layer is operable to attract the reflected electrons. Deposited on the collector layer is a phosphor layer that emits a photon of a known wavelength when activated by an attracted electron. A transparent layer that is oppositely positioned with respect to the pixel elements is operable to attract reflected electrons and prevent reflected electrons from striking the phosphor layer. Color displays are further contemplated by incorporating individually controlled sub-pixel elements in each of the pixel elements. The phosphor layers emit photons having wavelengths in the red, green or blue color spectrum.

Field-emission matrix display based on lateral electron reflections

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.
