Description

technical field [0001] The invention belongs to the fields of flat panel display technology, microelectronic science and technology, vacuum science and technology, and nano science and technology, and relates to device fabrication of flat panel field emission displays, in particular to carbon nanotube cathodes. The device manufacturing aspect of flat field emission display, especially relates to a flat panel display with branch-controlled inverted arch cathode structure and its manufacturing process. Background technique [0002] The field emission display device of carbon nanotube cathode is a new type of flat panel display device. Even better, it is also a concrete embodiment of an emerging flat display technology. Carbon nanotubes are a curly graphite layer structure with a diameter on the order of tens or tens of nanometers, so they have a smaller tip curvature radius and can emit a large number of electrons under the action of an applied electric field strength, while ...
