Abstract:
New, hybrid vacuum electron devices are proposed, in which the electrons are extracted from the nanotube into vacuum. Each nanotube is either placed on the cathode electrode individually or grown normally to the cathode plane. Arrays of the nanotubes are also considered to multiply the output current. Two- and three-terminal device configurations are discussed. In all the cases considered, the device designs are such that both input and output capacitances are extremely low, while the efficiency of the electron extraction into vacuum is very high, so that the estimated operational frequencies are expected to be in a tera-hertz range. New vacuum triode structure with ballistic electron propagation along the nanotube is also considered.
Abstract:
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.
Abstract:
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.
Abstract:
A display device utilizes a plurality of pixels arranged in a predetermined configuration for recording and displaying information. Each pixel includes a substrate and a light modulating material for selectively modulating a predetermined wave length of light by transitoning between a first and a second state in response to a heater element. The light modulating material in the first state causes destructive interference in the predetermined wave length of light and in the second state causes constructive interference in the predetermined wave length of light. The pixel structure is buried within an aerogel thereby minimizing the heat dissipation rate from the pixels.

Abstract:
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.
Abstract:
A display device utilizes a plurality of pixels arranged in a predetermined configuration for recording and displaying information. Each pixel includes a substrate and a light modulating material for selectively modulating a predetermined wave length of light by transitioning between a first and a second state in response to a heater element. The light modulating material in the first state causes destructive interference in the predetermined wave length of light and in the second state causes constructive interference in the predetermined wave length of light. The pixel structure is buried within an aerogel thereby minimizing the heat dissipation rate from the pixels.
