AI Technical Summary

Problems solved by technology

In the carbon nanotube cathode, only a small amount of carbon nanotubes can emit electrons, and the number of emitted electrons is not too much; while most of the carbon nanotubes do not emit electrons, and there are very few carbon nanotubes that emit electrons. The tubes conduct intermittent electron emission, which makes the electron emission efficiency of the overall carbon nanotube cathode very low

This is very unfavorable for improving the technical indicators such as the luminous brightness of the luminous backlight

Second, the control ability of the gate voltage on the carbon nanotube cathode is relatively weak

However, if the gate voltage cannot control the electron emission of the carbon nanotube cathode, or the gate voltage can only weakly control the electron emission of the local carbon nanotube cathode, then the existence of the gate voltage will lose its original function. This is also without any promotional significance for effectively improving the luminous gray scale of the luminous backlight.

Third, the fabrication area of ​​the carbon nanotube cathode is relatively small, and there is not a sufficient number of carbon nanotubes
