Abstract: A field emission display panel device that incorporates carbon nanotube emitter layers for emitting electrons wherein the carbon nanotube layers has a smaller width than the conductive paste layers it is deposited on is disclosed. The width of the carbon nanotube layer should be less than null of the width of the conductive paste layer, or in a range between about null and null of the width of the conductive paste layer, i.e. such as a silver paste layer. The present invention novel structure prevents the overflow of the carbon nanotubes, after a curing process for the nanotubes is conducted, onto the sidewall of the conductive paste layer, and thus significantly improves the electron density projected toward the flourescent powder coating layer to produce an image with reduced electron scattering. As a result, image clarity, definition and contrast can be improved in the FED device.

Abstract: 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.

Abstract: A field emission display panel of the diode structure that has a dual-layer cathode and an anode formed on a bottom glass panel and a method for such fabrication are disclosed. In the FED panel, a plurality of emitter stacks is formed each having a layer of dielectric material, a first layer of a conductive paste coated with a layer of nanotube emitters on a peripheral, sidewall surface as a cathode, and a second layer of the conductive paste deposited on top of the nanotube emitter layer. The first layer and the second layer are formed in a column shape. The second conductive paste layer stops any nanotubes left on a top surface of the first conductive paste layer from emitting electrons in an upward direction and restricts all emitted electrons in a downward direction.
