technical field [0001] The present invention belongs to the fields of vacuum science and technology, display technology, nano science and technology, microelectronics science and technology, optoelectronics science and technology and integrated circuit science and technology, and relates to a flat field emission display The manufacture specifically relates to the manufacture of a planar field emission luminescent display with a carbon nanotube cathode, and particularly relates to the manufacture and manufacturing process of a luminescent display with a high-low flat-arc polymerization single-gated obliquely placed closed curved surface ring edge cathode structure. Background technique [0002] Carbon nanotubes have been successfully fabricated as highly efficient cold cathodes in field emission displays. As long as a strong enough electric field is formed on the surface of carbon nanotubes, the carbon nanotubes can be forced to emit a large number of electrons, thereby formi...

AI Technical Summary

Problems solved by technology

However, due to the unreasonable manufacturing structure, the gate operating voltage is too high, which virtually increases the power loss of the light-emitting display; too high gate operating voltage is also extremely easy to cause electrical breakdown between the cathode and the gate. phenomenon occurs, causing permanent damage to the light-emitting display

In addition, the ability of the gate to control the electron emission of carbon nanotubes is very low. Whether many carbon nanotubes emit electrons is not completely controlled by the gate operating voltage.

Second, the production of large-area carbon nanotube layers

Obviously, without enough carbon nanotubes for electron emission, it is impossible to form a large anode working current. Therefore, it is necessary to make a large-area carbon nanotube layer

However, an excessively large carbon nanotube layer occupies the limited area of ​​the cathode plate in the light-emitting display, which will cause a single display pixel of the light-emitting display to be too large and reduce the display resolution of the light-emitting display.

Third, the electron emission capability of carbon nanotubes

The existence of the ineffective electron source layer not only squeezes and wastes the limited cathode plate area, but also reduces the success rate of light-emitting displays
