Abstract: A diode structure field emission display panel that utilizes a nanotube emitter layer as the electron source and having a cathode and an anode formed on the same panel substrate is provided. The electron source of the nanotube emitter layer can be suitably formed by nanometer dimensioned hollow tubes of carbon, diamond or diamond-like carbon mixed with a polymeric-based binder. The nanotube emitter material can be advantageously applied on top of an electrode layer such as a silver paste by a low cost thick film printing technique. Since both the cathode and the anode are formed on the same bottom glass plate, the operating voltage is controlled by the thickness of a dielectric material layer that is used to form the nanotube emitter stacks. As a result, the distance between the top glass plate and the bottom glass plate can be suitably selected to allow a rapid evacuation of the panel cavity to form a high vacuum therein without affecting the operating voltage of the device. The present invention novel diode structure FED can be fabricated in large areas and at a low cost.

Abstract: The present invention relates to a field emitter array used in various devices including a nanotube-based display and a microwave-amplifying device. In prior art, an electron accelerated by an electric field collides, for example, with a phosphor on the screen. Light is emitted as a positive ion drops out of the phosphor. Destruction or deformation of the emitter's structure can occur if the positive ion becomes accelerated and collides with the emitter, which results in instability or interruption of the emitter's operation. According to the present invention, coating a carbon nanotube with a very thin semiconductor or insulating material with a high degree of hardness can protect the carbon nanotube from the external particles (particularly, positive ions). The thin layer also provides for easy electron emission under low voltage, thereby greatly improving the uniformity and stability of electron emission.

Abstract: An electron-emitting device in which the specific capacitance and the drive voltage are reduced, and which is capable of obtaining a finer electron beam by controlling the trajectory of emitted electrons. An electron-emitting portion of an electron-emitting member is positioned between the height of a gate and the height of an anode. When the distance between the gate and a cathode is d; the potential difference at driving the device is V1; the distance between the anode and the substrate is H; and the potential difference between the anode and the cathode is V2, then the electric field E1nullV1/d during driving is configured to be within the range from 1 to 50 times E2nullV2/H.

Abstract: A method and an apparatus capable of instantaneously forming a surface of an arc-treated material mainly consisting of graphite into nano-tubes due to arc discharge carried out using a unit like a welding arc torch or the like without necessarily requiring a processing container, resulting in the nano-tube being applied to an electron emission source. A torch electrode acting as a first electrode and the arc-treated material made of graphite and acting as a second electrode are arranged opposite to each other. A potential is applied between both electrodes to generate arc discharge therebetween. A mask having an opening pattern is arranged on the arc-treated material, so that only graphite positioned on portions of a surface of the arc-treated material 2 corresponding to openings of the mask are exposed to arc, to thereby be formed into nano-tubes.

Abstract: A field emitter cell includes a thin-film-edge emitter normal to the gate layer. The field emitter cell may include a conductive substrate layer, an insulator layer having a perforation, a gate layer having a perforation, an emitter layer, and other optional layers. The perforation in the gate layer is larger and concentrically offset with respect to the perforation in the insulating layer and may be of a tapered construction. Alternatively, the perforation in the gate layer may be coincident with, or larger or smaller than, the perforation in the insulating layer, provided that the gate layer is shielded from the emitter from a direct line-of-sight by a nonconducting standoff layer. Optionally, the thin-film-edge emitter may include incorporated nanofilaments. The field emitter cell has low gate current, making it useful for various applications such as field emitter displays, high voltage power switching, microwave, RF amplification and other applications that require high emission currents.

Abstract: A vacuum fluorescent display includes a cathode electrode, grid electrode, anode electrode, at least one envelope, phosphor screen, and cap. The cathode electrode emits electrons. The grid electrode extracts the electrons from the cathode electrode. The anode electrode accelerates the electrons extracted from the cathode electrode. The envelope accommodates the cathode electrode, grid electrode, and anode electrode in a vacuum space and has a phosphor screen plate having light transmission properties. The phosphor screen is formed on an inner surface of the phosphor screen plate of the envelope and adapted to emit light upon bombardment of the electrons accelerated by the anode electrode. The cap is made of an X-ray shielding material and supported outside the envelope so as to surround the phosphor screen plate of the envelope through a gap. The cap has a light exit portion from which the light emitted from the phosphor screen emerges through the phosphor screen plate of the envelope.
