The light-emitting display disclosed by the invention has the advantages of being high in light-emitting brightness, low in manufacturing cost and simple in manufacturing process.

Description

technical field [0001] The present invention belongs to the fields of microelectronic science and technology, nanometer science and technology, vacuum science and technology, optoelectronic science and technology, integrated circuit science and technology and plane display technology, and relates to plane field emission luminescence The manufacture of the display specifically relates to the manufacture of a planar field emission luminescent display of a carbon nanotube cathode, in particular to a luminescent display with a hyperbolic laminated gate-controlled structure of a multi-discontinuous slanted tape circular frustum cylinder body surface. Background technique [0002] Carbon nanotubes are nanopolar tubular materials with high aspect ratios, and are black film materials from a macroscopic point of view. In a vacuum environment, as long as a strong electric field is formed on the surface of carbon nanotubes, carbon nanotubes can continuously emit electrons. Taking adva...

Problems solved by technology

[0003] However, there are still many technical problems that need to be solved urgently in the field emission light-emitting display with a three-pole structure.

For example, limited by the production structure, the production area of ​​the carbon nanotube layer is usually very small, which means that the number of carbon nanotube cathodes is reduced; without a sufficient number of carbon nanotubes for electron emission, it is impossible to provide enough for a light-emitting display. cathodic current, so it is necessary to increase the fabrication area of ​​the carbon nanotube layer as much as possible

For example, the electron emission efficiency of carbon nanotubes is very low. Some carbon nanotubes can only emit a small amount of electrons under the action of strong electric field strength,...
