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 the flat panel field emission display, in particular relates to a flat panel display with a lower gate-controlled suspended annular cathode emission structure and its manufacturing process. Background technique [0002] The field emission display is a solid vacuum flat display device, which uses a dot matrix arrangement of cold cathodes to emit electrons to ensure stable and reliable display performance, bright colors and high resolution. Carbon nanotubes can emit a large number of electrons under the action of an external electric field, and are a cold cathode material with excellent performance. Therefore, carbon nanotube field em...
