  • Publication number: 20050168131
    Abstract: A field emission display comprises an anode comprising a matrix of pixels and a cathode comprising an insulating layer defining a plurality of wells having a conductor therein. A first conductive layer forms a plurality of conductive pads, each of the conductive pads corresponding to one of the wells. A plurality of nanostructures are electrically coupled to the conductive pads. A second conductive layer is formed over the insulating layer and provides a plurality of gate electrodes. When a potential between the conductive pads and gate electrodes exceeds a threshold voltage, the nanostructures emit electrons that impinge on the pixels.

    Abstract: A solid-state cold-cathode flat panel display a using thin-film-transistor (TFT) circuit is disclosed. Associated with each pixel element is a TFT circuit comprising a first and second transistor electrically cascaded and a capacitor in communication with an output of the first device and an output of the second device that may be used both to selectively address pixel elements in the display and hold pixels in their states for the frame time. Cold cathode sources are used to emit electrons that are drawn to selected pixel elements that include phosphor pads, which emit light of a known wavelength when struck by the emitted electrons.

  • Publication number: 20050161668
    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.

  • Publication number: 20040245225
    Abstract: New method of introducing color to two- and three-dimensional images produced in glass or any other transparent media with laser induced micro-explosions, is proposed. The method is based on utilization of a special color film, which consists of multiple periodically repeating transparent stripes of filters of major Red, Green and Blue (RGB) colors. The color film is attached to the glass in front of the image, while external parallel beam of white light illuminates the image through this color film. The image becomes subdivided into multiple color stripes (for two-dimensional image) or slices (for three-dimensional image), which thus transform the image into RGB color sub-pixels. The computer program places the visible dots, resulting from the micro-explosions, into corresponding sub-pixel areas to reproduce the original colors of the image stored in the computer memory. If the sub-pixel pitch is sufficiently short, the human eye perceives the image as a colored one.

  • Patent number: 6614149
    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.
