Description

Light-emitting backlight source with asymmetric opposite hollow-faced cathode inclined hook top arc gate control structure
Technical Field
The invention belongs to the field of intercrossing of integrated circuit science and technology, nano science and technology, plane display technology, microelectronic science and technology, vacuum science and technology, semiconductor science and technology and photoelectron science and technology, and relates to the manufacture of plane light-emitting backlight sources, in particular to the manufacture of a plane light-emitting backlight source of a carbon nano tube cathode, in particular to a light-emitting backlight source of an asymmetric opposite concave surface cathode inclined hook top arc gate control structure and a manufacture process thereof.
Background
The planar light-emitting backlight source is a vacuum component, and has been applied to various large-scale scientific research equipment, and the cathode material thereof can be made of carbon nanotubes. Therefore, the carbon nanotube cathode is an important component of the light-emitting backlight source component, because the carbon nanotube cathode can provide cathode current for the light-emitting backlight source. With the forward research on the carbon nanotube cathode, the light emitting quality of the light emitting backlight source can be promoted to be greatly developed. However, there are some technical difficulties to be overcome in the light emitting backlight of the three-pole structure. First, the carbon nanotube cathode provides a relatively small number of cathode electrons. In the carbon nanotube layer, not all the carbon nanotubes can provide cathode electrons to the light-emitting backlight, and a small part of the carbon nanotubes can normally emit electrons, but the number of the cathode electrons provided by the carbon nanotubes is not too large, and a large part of the carbon nanotubes do not emit electrons, which certainly cannot contribute to a large cathode current of the light-emitting backlight. Most of the carbon nanotubes occupy the area for making the carbon nanotubes and do not emit cathode electrons, and may interfere with other carbon nanotubes to emit electrons, so that the existence of the ineffective carbon nanotube cathode should be eliminated as much as possible. Second, the controlled performance of carbon nanotube cathodes is weak. The gate voltage is responsible for controlling the electron emission of the carbon nanotube, but after the gate voltage is applied, high electric field intensity cannot be effectively formed on the surface of the carbon nanotube cathode, so that the carbon nanotube cathode cannot emit electrons naturally. If the applied gate voltage is too high, it may also cause an electrical breakdown between the gate and the cathode. These technical difficulties also need to be considered.
