Problems solved by technology

First, limited by the structure of the display and the manufacturing process of the display, the production area of ​​the carbon nanotube cathode is very small, which makes it impossible to effectively increase the electronic current of the light-emitting display because there are not enough carbon nanotubes to provide a large amount of electrons for the display. It is impossible to further improve the luminous brightness of luminous displays.
Second, in the light-emitting displays produced, the emission efficiency of carbon nanotubes is relatively low
After applying an appropriate gate voltage, some carbon nanotubes can emit electrons, but the number of emitted electrons is not much, and some carbon nanotubes do not emit electrons at all, and there are not enough carbon nanotubes for electron emission. Emission, light-emitting display is unable to form an effective electronic current
Third, the control ability of the gate electrode to the carbon nanotube cathode is very weak, and even in many cases, the gate electrode loses the control performance of the application for the carbon nanotube cathode. The surface of the cathode of the tube cannot form a strong electric field at all.
