Problems solved by technology

However, in most of the currently produced carbon nanotube cathode field emission display devices, although the reported grid voltage has greatly improved in value, there is still a long way to go when it is connected with a conventional integrated drive circuit. A very long distance, the current device gate operating voltage is far higher than the voltage that the integrated circuit can withstand

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 particularly relates to a flat panel display with a side-gate-controlled circular mesa cathode emission structure and its manufacturing process. Background technique [0002] The display is an important output device in information display technology. Its function is to convert the emitted electrical signal into a light signal after a series of processing, and finally display it in the form of text and images. Among many flat panel display devices, carbon nanotube cathode field emission display is a new type of planar device, which has many advantages such as high brightness, high definition, low...
