AI Technical Summary

Problems solved by technology

[0003] However, there are still many technical problems to be solved in the field emission light-emitting display of the triode structure.

For example, one, the control ability of the gate electrode to the carbon nanotube cathode is very weak

The specific performance is: when the gate voltage is applied to the gate, the number of electrons emitted by the carbon nanotube cathode is very small, or many carbon nanotubes do not emit electrons at all. From a macro perspective, it is impossible to form a large The current of the luminous display, which is not helpful to improve the technical indicators of the luminous display such as luminous brightness, luminous gray scale, etc., but also makes the gate electrode production lose its original meaning

Due to the short distance between the gate and the cathode, the gate voltage of the light-emitting display is usually very low when it works normally, but because the gate cannot control the carbon nanotube cathode, it often causes the phenomenon of excessive gate voltage. It would be disadvantageous to further reduce the production cost of emissive displays

Second, the electron emission efficiency of the carbon nanotube cathode is relatively low. Under the same gate voltage, the number of carbon nanotubes capable of electron emission is seriously insufficient.

Third, the fabrication area of ​​the carbon nanotube cathode is too small, resulting in a small number of carbon nanotubes that can emit electrons, and even fewer carbon nanotubes that can emit a large amount of electrons.
