Problems solved by technology

Among the currently reported developed devices, there are generally unfavorable factors such as high gate operating voltage and low display brightness of the overall device, which need to be further resolved
Although the grid operating voltage can be effectively reduced by reducing the distance between the grid structure and the carbon nanotube cathode structure, it is also restricted by factors such as the manufacturing process and material properties of the insulating material, and it is impossible to reduce the distance without limit. Otherwise, it is easy to cause electrical breakdown phenomenon
