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 panel field emission display, in particular relates to a flat panel display with suspended annular cathode structure and its manufacturing process. Background technique

[0002] Field emission displays use a working principle similar to traditional cathode ray tube displays, that is, electron beams are used to bombard phosphors on the screen to emit visible light. This enables the field emission display to combine the bright and clear high-quality images of the cathode ray tube with the lightness and thinness of the liquid crystal display. It has the advantages of high definition, high brightness, high resolution and low power c...
