AI Technical Summary

Problems solved by technology

As we all know, in a small area of ​​carbon nanotube layer, the number of carbon nanotubes is seriously insufficient; there is not a sufficient number of carbon nanotubes for electron emission, which obviously cannot effectively improve the anode operating current of the light-emitting display, and is not conducive to enhancing the light-emitting display of luminous brightness

In addition, the control ability of the gate electrode to the carbon nanotube cathode is very weak

When an appropriate gate operating voltage is applied, some carbon nanotubes can emit electrons, while some carbon nanotubes cannot emit electrons; at the same time, under the same gate operating voltage, the number of carbon nanotubes emitting electrons is seriously insufficient, these Both reflect the weakening of the control performance of the gate electrode on the carbon nanotubes
