Description
Technical Field
The invention belongs to the field of semiconductor science and technology, photoelectron science and technology, vacuum science and technology, microelectronic science and technology, integrated circuit science and technology, nano science and technology and planar display technology, and relates to the manufacture of planar light-emitting backlights, in particular to the manufacture of planar light-emitting backlights with carbon nanotube cathodes, and especially to a light-emitting backlight with a single-connection-ring circular convex surface cathode multi-swallow-wing arc gate control structure and a manufacture process thereof.
Background
The carbon nano tube has small tip curvature radius and extremely high mechanical property, and is a cathode material with excellent electric conduction capability. In view of the large-scale popularization of the screen printing process, the realization of manufacturing the patterned and planarized carbon nanotube cathode is realized, and the great promotion of the application of the carbon nanotube cathode in the light-emitting backlight equipment is also realized. A light emitting backlight using carbon nanotubes as cathode material is a new type of vacuum device.
However, in the light emitting backlight of the three-pole structure, there are some technical difficulties to be solved urgently. Such as: first, the gate has poor control over the carbon nanotube cathode. Specifically, when a proper voltage is applied to the gate, the amount of electron emission from the carbon nanotube layer does not change with the change of the gate voltage, or sometimes changes with the change of the gate voltage, but sometimes the electron emission from the carbon nanotube layer is not controlled by the changed gate voltage. Second, the electron emission efficiency of the carbon nanotube is low. In the carbon nanotube layer, only a small part of carbon nanotubes can perform normal electron emission, a considerable number of carbon nanotubes emit fewer electrons, and even a part of carbon nanotubes do not emit electrons at all; in general, carbon nanotubes emit a small number of electrons, which makes it impossible to form a large current of a light emitting backlight. Third, the carbon nanotube cathode has a small fabrication area. Limited by high resolution technical index, the manufacturing area of the carbon nanotube cathode is not too large; however, the small area of the carbon nanotube cathode, i.e., the small number of carbon nanotubes, is also a reason why a large current cannot be generated in the light emitting backlight. These technical difficulties also require careful consideration and study, and have been addressed only by measures.

Has the advantages that: the invention has the following remarkable progress:
firstly, in the single-connecting-ring circular convex surface cathode multi-swallow-wing arc gate control structure, a gate swallow-wing electrode front layer, a gate swallow-wing electrode rear layer and a gate swallow-wing electrode upper layer are manufactured. The front layer of the gate swallow-wing electrode, the rear layer of the gate swallow-wing electrode and the upper layer of the gate swallow-wing electrode are mutually communicated. Through the gate electrode silver thick wire layer, the voltage applied from the outside can be smoothly transmitted to the surface of the carbon nano tube layer, so that strong electric field intensity is formed, and the carbon nano tube layer is forced to carry out electron emission. On one hand, the front layer of the gate swallow-wing electrode, the rear layer of the gate swallow-wing electrode and the upper layer of the gate swallow-wing electrode have good conductivity, so that gate potential can be smoothly transmitted, and on the other hand, the front layer of the gate swallow-wing electrode, the rear layer of the gate swallow-wing electrode and the upper layer of the gate swallow-wing electrode jointly regulate and control electron emission of the carbon nano tube layer, so that the manufacturing yield of the light-emitting backlight source is remarkably improved.
Secondly, in the single-connecting-ring circular convex surface cathode multi-swallow-wing arc gating structure, a cathode ring circular bottom electrode is manufactured. The cathode ring round bottom electrode is positioned on the upper surface of the outer layer of the cathode ring convex base, surrounds the inner layer of the cathode ring convex base and has a larger surface area; the carbon nanotube layer is formed on the cathode ring round bottom electrode, which means that the forming area of the carbon nanotube layer is effectively increased in the light emitting backlight source. This is advantageous for further increasing the cathode current of the light-emitting backlight and enhancing the light-emitting brightness of the light-emitting backlight.
Thirdly, in the cathode multi-swallow-wing arc gate control structure with the single connecting ring and the circular convex surface, the carbon nanotube layer is manufactured on the cathode ring and the circular bottom electrode. On one hand, the cathode ring round bottom electrode has a large upper edge and a large lower edge of the electrode, and can fully utilize the phenomenon of 'edge electric field enhancement' to ensure that the carbon nano tube can emit more electrons; on the other hand, the upper edge of the cathode ring round-bottom electrode is in a polygonal shape, and the lower edge of the cathode ring round-bottom electrode is in a polygonal shape, so that the utilization of the phenomenon of 'fringe electric field enhancement' is further enhanced. This is helpful for further improving the brightness adjustability of the light-emitting backlight, improving the brightness of the light-emitting backlight, and enhancing the emission current of the light-emitting backlight.
In addition, no special manufacturing process is adopted in the manufacturing process of the single-connection-ring circular convex surface cathode multi-swallow-wing arc gate control structure, so that the manufacturing yield of the light-emitting backlight source is improved.
