AI Technical Summary

Problems solved by technology

At present, the effective distance between the gate and the cathode is too large, which causes the phenomenon that the gate operating voltage remains high and the control effect of the gate on the carbon nanotubes is greatly weakened; at the same time, the fabrication of the gate The structure is too complicated, which virtually increases the production cost of the overall light-emitting display

The production area of ​​the carbon nanotube cathode is too small, which will directly lead to a substantial reduction in the anode operating current, which is not conducive to further improving the luminous intensity of the field emission light-emitting display; in the carbon nanotube cathode, the effective carbon nanotubes capable of electron emission are also It is also unfavorable to improve the electron emission efficiency of carbon nanotubes
