Problems solved by technology

[0003] However, there are still many technical problems to be solved in the field emission light-emitting display with a three-pole structure.

For example, the fabrication area of ​​the carbon nanotube layer in a field emission light-emitting display is very small, which means that the number of carbon nanotubes is reduced; without a sufficient number of carbon nanotubes for electron emission, it is impossible to form a large cathode current, then The technical indicators such as the improvement of the luminous brightness of the luminous display and the adjustable luminous gray scale cannot be improved and adjusted.

For example, in a field emission display, although the gate is made on the top of the carbon nanotube cathode, the control of the gate on the carbon nanotube cathode is very weak. After the gate voltage is applied, some carbon nanotubes emit a small amount. , even many carbon nanotubes do not emit electrons at all, even if a small amount of carbon nanotubes emit a large number of electrons, the cathode current formed by them is very weak; Performance indicators such as luminous grayscale adjustability cannot be optimized
