The invention relates to a
flat panel display of
cathode structure of
branch controlled inverted arch and a fabrication process thereof, and the
flat panel display comprises a sealed
vacuum chamber formed by an anodic glass panel, a cathodic glass panel and
peripheral glass
enclosure frames, a
supporting wall structure and an
getter auxiliary element, wherein the anodic glass panel is provided with an anodic conductive layer and a fluorescent
powder layer prepared on the anodic conductive layer and the
supporting wall structure and the
getter auxiliary element are arranged between the anodic glass panel and the cathodic glass panel, and the cathodic glass panel is provided with a grid lead wire layer, a carbon nanometer tube and the
cathode structure of
branch controlled inverted arch. The invention is capable of increasing the electronic emission area and the electronic
emission efficiency of a
cathode of the carbon nanometer tube and reducing
grid voltage, and has the advantages of stable and reliable manufacturing process, simple fabrication process, low manufacturing cost and simple structure.
