Problems solved by technology

In most current field emission displays, either the gate operating voltage required to force the carbon nanotubes to emit a large amount of electrons remains high, or the gate current is too large, or the gate current is too high at a low gate voltage. The anode current is too small, that is to say, there are not enough carbon nanotube cathodes to emit a sufficient amount of electrons, etc., and these factors influence and restrict each other at the same time. There is no relatively complete solution. Many scientific research units have It is to improve another technical indicator after sacrificing a certain technical indicator

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 production aspect of flat panel field emission display, especially relates to a flat panel display with multi-coaxial cylinder side grid control structure and its production process. Background technique [0002] The carbon nanotube field emission display is a new type of active light-emitting fully solidified flat panel display. The working principle of this display is almost the same as that of the traditional cathode ray tube display. It uses electron beams to bombard the phosphor layer to emit visible light. , which retains the advantages of high brightness, high display image quality, fast response speed, and large viewing angle of a cathode ray tube d...
