摘要： A field emission display panel that utilizes nanotube emitters as electron sources and is equipped with two cathodes i.e. a primary cathode and an auxiliary cathode, and an anode is provided. The nanotube emitters can be suitably formed by nanometer-dimensioned hollow tubes of carbon, diamond or diamond-like carbon mixed in a polymeric-based binder. The nanotube emitters are formed in two parallelly-positioned, spaced-apart rows on top of an electrode layer such as a silver paste by a thick film printing technique. Since both the primary cathode and the anode are formed on the bottom glass plate, the operating voltage can be controlled by the thickness of the dielectric layer that is used in forming the nanotube emitter stacks. An auxiliary cathode formed of an electrically conductive material is coated on the interior surface of a top glass plate to further repel electrons in a downward direction toward the anode on the bottom glass plate. As a result, the distance between the top plate and the bottom plate can be chosen to allow the rapid evacuation of the panel cavity to form a high vacuum therein without affecting the operating voltage of the device. The present invention novel FED panel can be fabricated with a large panel area and at a low cost.

摘要： An improved cold cathode emitter based on carbon nanotubes has been developed by inserting into the conventional process an extra step in which the diameter of the gate aperture is temporarily reduced by means of a conformally deposited sacrificial layer. This reduced diameter aperture is then used as a mask for the deposition of the catalytic layer. The latter is then converted to a discontinuous layer either by selective etching or by heating until agglomeration occurs. The sacrificial layer is removed, following which carbon nanotubes are grown upwards from the catalytic layer in the normal manner. Because of the greater distance between the tubes and the gate aperture that this process provides, a more reliable product is obtained.

摘要： A field emission display device utilizing a nanotube emitter layer instead of microtips and a method for fabricating such device by a thick film printing technique instead of thin film deposition and photolithographic methods are provided. In the device, various layers of materials including a layer of nanotube emitter material can be formed by a thick film printing technique on a glass plate. The nanotube emitter material can be nanotubes of carbon, diamond or a diamond-like carbon material that is mixed with a solvent-containing paste. The resulting paste has a consistency suitable for a thick film printing process. The nanotubes should have diameters between about 30 nanometers and about 50 nanometers for use in the present invention device. The screen printing or the thick film printing method of the present invention can be carried out at substantially lower cost than the thin film deposition and photolithographic methods. Furthermore, no size limit is imposed in the thick film printing technique in contrast to a substrate size limit due to a deposition chamber used in a thin film deposition process. The present invention novel method is especially suitable for the fabrication of large-size FED screens.

摘要： 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.
