Field emission display panel having cathode and anode on the same panel substrate
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.
