AI Technical Summary

Problems solved by technology

Second, the fabrication area of ​​the carbon nanotube cathode is too small

Without a certain amount of carbon nanotubes for electron emission, it is impossible to reach the rated operating current required by the light-emitting display, so it is not surprising that the various image technical indicators of the light-emitting display have declined

Third, the gate-cathode distance is too large

Because the distance between the gate and the cathode is too large, in order to achieve the electric field strength necessary for carbon nanotubes to emit electrons, it is usually the only feasible way to increase the gate operating voltage; Both are very high, which virtually increases the power consumption of the light-emitting display, and also increases the cost of the driving circuit of the light-emitting display.

In addition, although the carbon nanotubes can carry out field electron emission after the gate operating voltage is applied, the number of electrons emitted by the carbon nanotubes cannot change with the change of the gate operating voltage. Typical problems that the cathode cannot be effectively regulated
