Problems solved by technology

Second, the fabrication area of ​​the carbon nanotube layer is too small
Without a sufficient number of carbon nanotubes for simultaneous electron emission, it is impossible to form the large cathode current required for the normal operation of the luminous backlight. After all, the number of electrons emitted by a single carbon nanotube is limited.
Third, the electron emission efficiency of the carbon nanotube cathode is very low
Some carbon nanotubes can emit a small amount of electrons, and most carbon nanotubes ignore the existence of the gate voltage and do not emit electrons at all, thus forming an invalid carbon nanotube layer
