Abstract: A multiplexed grid structure for electron emission displays allows each of the grid portions to be independently controllable from each other so that electrons can be emitted from their respective pixel sites as each grid portion is addressed.

Abstract: A device for testing flat panel displays includes an interface having compliant bumps mounted thereon, which make electrical contact with pads on the display panel. The interface may have a hole formed therein for allowing the passage of light therethrough when the interface is mounted on the display panel. The compliant bumps ensure that all of the bumps make sufficient electrical contact with the pads.

Abstract: A plurality of field emission device cathodes each generate emission of electrons, which are then controlled and focused using various electrodes to produce an electron beam. Horizontal and vertical deflection techniques, similar to those used within a cathode ray tube, operate to scan the individual electron beams onto portions of a phosphor screen in order to generate images. The use of the plurality of field emission cathodes provides for a flatter screen depth than possible with a typical cathode ray tube.

Abstract: Carbon nanotubes are aligned within a host phase of a material that has molecules that will align under a certain influence. When the host molecules become aligned, they cause the carbon nanotube fibers to also become aligned in the same direction. The film of aligned carbon nanotubes is then cured into a permanent phase, which can then be polished to produce a thin film of commonly aligned carbon nanotube fibers for use within a field emission device.

Abstract: Before submitting a sample, including a first material layered upon a substrate, to an ion milling process, whereby a second material is sputtered onto the surface of the first material and the sample is then submitted to an etching process, an irregularity is formed on the surface of the first material. The overall process results in the formation of cones, or micro-tip structures, which may then be layered with a layer of low work function material, such as amorphous diamond. The irregularity in the surface of the first material may be formed by polishing, sandblasting, photolithography, or mechanical means such as scratching.

Abstract: A film (carbon and/or diamond) for a field emitter device, which may be utilized within a computer display, is produced by a process utilizing treatment of a substrate and then depositing the film. The treatment step creates nucleation and growth sites on the substrate for the film deposition process and promotes election emission of the deposited film. With this process, a patterned emission can be achieved without post-deposition processing of the film. A field emitter device can be manufactured with such a film.

Abstract: An apparatus for testing semiconductor devices including probe tips for contacting input/output pads on the device attached to a probe membrane fixed to a package using a layer of elastomeric material. The elastomeric material and use of compliant bump probe tips effect a global planarization for improved electrical contact between the probe assembly and the input/output contacts on the device under test.

Abstract: On a field emission cathode, emission from the edges of metal conducting feedlines is inhibited, or even eliminated, by depositing a dielectric film over the edges before deposition of the field emitter material. Surface treatment of the metal conducting feedlines or substrate may be performed to enhance the field emission properties of the field emitter at preferential locations.

Abstract: A system and method for producing uniform energy dissipation in display pixels with widely varying electrical characteristics in order to equalize light output and improve yield within a matrix addressable display panel. The present invention is implemented within a driver circuit utilizing the concept of current integration. A reference voltage, which is proportional to the most efficient pixel within the display is compared to the energy dissipated within a particular pixel during illumination of that pixel. A current mirror circuit supplies a current equivalent to the current provided to the object pixel to an integrator circuit resulting in a rising voltage within the integrator circuit. The rising voltage is proportional to the energy being dissipated within the current pixel. Once the rising voltage is equal to or greater than the reference voltage, current is removed from the object pixel.

Abstract: A field emission cathode for use in flat panel displays is disclosed comprising a layer of conductive material and a layer of amorphic diamond film, functioning as a low effective work-function material, deposited over the conductive material to form emission sites. The emission sites each contain at least two sub-regions having differing electron affinities. Use of the cathode to form a computer screen is also disclosed along with the use of the cathode to form a fluorescent light source.

Abstract: A cathode assembly includes a substrate (1101), a plurality of electrically conductive strips (1102), nano-size diamond particles (1701), and a layer (1801) of diamond material deposited (CVD) over the diamond particles (1701).

Abstract: A film (carbon and/or diamond) for a field emitter device, which may be utilized within a computer display, is produced by a process utilizing etching of a substrate and then depositing the film. The etching step creates nucleation sites on the substrate for the film deposition process. With this process patterning of the emitting film is avoided. A field emitter device can be manufactured with such a film. A field emission device results where the cathode has a continuous film that has not been subjected to etching, and thus has superior emission properties. A pixel in the cathode includes the emitting film deposited directly on the substrate with the conductor deposited on one or more sides of the emitter film. In one embodiment the emitter is in a window formed in the conductor layer.
