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...

AI Technical Summary

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, and most carbon nanotubes do not emit electrons at all, and only a small number of carbon nanotubes emit electrons. It is not enough to emit electrons to form the cathode electron source of light-emitting displays

For example, the control performance of the gate electrode on the carbon nanotube layer is very weak

When a large gate voltage is applied on the gate, a strong electric field strength cannot be formed on the surface of the carbon nanotube layer, so it is impossible to allow the carbon nanotubes to emit a large amount of electrons; and once the gate voltage exceeds High, it is also extremely easy to cause a short circuit between the gate and the cathode, so that the insulating material of the light-emitting display is broken down, resulting in permanent damage to the light-emitting display
