AI Technical Summary

Problems solved by technology

Due to the small fabrication area of ​​the carbon nanotube layer, there are not enough carbon nanotubes for field electron emission, so it is impossible to provide a sufficient anode operating current for the light-emitting display

At the same time, in the produced carbon nanotube layer, not all carbon nanotubes can emit a large amount of electrons. Some carbon nanotubes emit a small amount of electrons, and some carbon nanotubes do not emit electrons at all. , which is also the reason for the low anode current of the light-emitting display

Second, the gate regulation problem

The number of electrons emitted by carbon nanotubes is not controlled by the gate operating voltage at all, and does not change with the magnitude of the gate operating voltage; too large a gate operating voltage cannot form a larger anode of a light-emitting display However, it is easy to cause electrical breakdown between the gate and the cathode, resulting in permanent damage to the light-emitting display

Therefore, the existence of the gate structure loses its original meaning

Third, the integrated fabrication of carbon nanotube cathodes and gates

Otherwise, the progress of the subsequent process may cause damage to the previously produced structure and reduce the quality of the light-emitting display.
