AI Technical Summary

Problems solved by technology

Second, the fabrication area of ​​the carbon nanotube layer is small

Third, the electron emission efficiency of the carbon nanotube layer is very low

In the carbon nanotube layer, with the formation of a strong electric field, some carbon nanotubes can emit a small amount of electrons, and some carbon nanotubes can emit a large number of electrons, but there are still a large part of the carbon nanotubes that are not at all Electron emission is not carried out, which is also a disadvantageous factor that the light-emitting backlight cannot form a large cathode current
