AI Technical Summary

Problems solved by technology

Second, the number of electrons emitted by the carbon nanotube cathode is relatively small
In the carbon nanotube cathode, only a small number of carbon nanotubes can emit electrons, and many carbon nanotubes, although they have been fabricated in the cathode material, are ineffective carbon nanotube cathodes and cannot actually emit electronic
The presence of ineffective carbon nanotube cathodes also wastes valuable carbon nanotube cathode fabrication area
Third, the control ability of the gate electrode in the light-emitting backlight to the carbon nanotube cathode is relatively low
The gate voltage applied to the gate does not have an application effect on the electron emission of the carbon nanotube cathode, and its essential function is greatly weakened
The above-mentioned technical difficulties still require the careful exploration of many scientific researchers.
