Technical field [0001] The invention belongs to the field of flat display technology, semiconductor science and technology, nanoscience and technology, vacuum science and technology, microelectronics science and technology, integrated circuit science and technology, and optoelectronic science and technology. It relates to the production of a flat light-emitting backlight, in particular to the production of a flat light-emitting backlight with a carbon nanotube cathode, and in particular to a light-emitting backlight with a double-arch flat gated structure with a non-continuous depression of the cathode and Its production process. Background technique [0002] The light-emitting backlight is a component with excellent image quality, and its cathode can be made of carbon nanotubes. In a suitable vacuum environment, carbon nanotubes can emit electrons, and the emitted electrons form the cathode current required for the normal operation of the light-emitting backlight. Therefore, t...

AI Technical Summary

Problems solved by technology

Second, the number of electrons emitted by the carbon nanotube cathode is relatively small

In the carbon nanotube cathode, only a small number of carbon nanotubes can emit electrons, and many carbon nanotubes, although they have been fabricated in the cathode material, are ineffective carbon nanotube cathodes and cannot actually emit electronic

The presence of ineffective carbon nanotube cathodes also wastes valuable carbon nanotube cathode fabrication area

Third, the control ability of the gate electrode in the light-emitting backlight to the carbon nanotube cathode is relatively low

The gate voltage applied to the gate does not have an application effect on the electron emission of the carbon nanotube cathode, and its essential function is greatly weakened

The above-mentioned technical difficulties still require the careful exploration of many scientific researchers.
