technical field [0001] The invention belongs to the fields of nanometer science and technology, display technology, integrated circuit science and technology, microelectronics science and technology, vacuum science and technology, and optoelectronic science and technology, and relates to planar field emission luminescent displays production, specifically related to the production of planar field emission luminescent displays with carbon nanotube cathodes, and in particular to the production and production of a luminescent display with a three-arc twill single-gate control multi-convex circular cake layer concave surface cathode structure craft. Background technique [0002] Carbon nanotubes are a cathode material with excellent properties, so they can be fabricated as electron sources in field emission light-emitting displays. It is precisely because of the unique high aspect ratio characteristics of carbon nanotubes that carbon nanotubes can emit a large number of electron...

AI Technical Summary

Problems solved by technology

In the prepared carbon nanotube layer, there are not many carbon nanotubes that can effectively carry out electron field emission. Although a large number of carbon nanotubes have been successfully produced as cathode materials, due to the different values ​​of the open electric field strength, the carbon nanotubes are mass-produced. Buried and other reasons, many carbon nanotubes are unable to emit electrons

The electrons emitted by carbon nanotubes are the source of current for light-emitting displays; the number of electrons emitted by carbon nanotubes decreases, so it is impossible to improve the brightness of light-emitting displays

Second, the preparation area of ​​carbon nanotubes

Third, the effective control of carbon nanotubes by the gate

After an appropriate gate operating voltage is applied, carbon nanotubes cannot effectively emit electrons; even though carbon nanotubes have already emitted electrons, the number of emitted electrons is not controlled by the gate operating voltage. is a typical manifestation of gate runaway
