Description
Technical Field
The invention belongs to the field of planar display technology, the fields of nano science and technology, integrated circuit science and technology, microelectronic science and technology, optoelectronic science and technology, semiconductor science and technology and the field of vacuum science and technology, and relates to the manufacture of planar light-emitting backlights, in particular to the manufacture of planar light-emitting backlights with carbon nano tube cathodes, in particular to a light-emitting backlight with an angled spine ring circumference double-connection-surface cathode alternate oblique bow gate control structure and a manufacture process thereof.
Background
Under a proper vacuum environment, the carbon nano tube can perform electron emission, and the characteristic makes the carbon nano tube become a very proper cathode manufacturing material. With the large-scale popularization of the screen printing process, the manufacture of the large-area and graphical carbon nanotube cathode becomes very easy, and the manufacturing process of the carbon nanotube cathode is accelerated. The light-emitting backlight source manufactured by using the carbon nanotube cathode is a vacuum device; the accelerated development of carbon nanotube cathodes has undoubtedly promoted the development of light-emitting backlight devices.
However, in the light emitting backlight of the three-pole structure, there are some technical difficulties to be solved. For example, first, the electron emission efficiency of carbon nanotube cathodes is very low. Among the prepared carbon nanotube cathodes, some carbon nanotubes can emit more electrons, some carbon nanotubes can emit less electrons, and even a considerable portion of carbon nanotubes do not emit electrons at all, so that the electron emission efficiency of the carbon nanotube cathode is very low in general terms, and the formation of a large cathode current of the light-emitting backlight is also very unfavorable. Second, the gate voltage has very poor control performance for the carbon nanotube cathode. The function of the gate voltage is to control and regulate the electron emission of the carbon nanotube cathode, so that the quantity of the electrons emitted by the carbon nanotube cathode can be changed along with the change of the gate voltage; if the electron emission of the carbon nanotube cathode does not strictly follow the gate voltage, it means that the controllability of the carbon nanotube cathode by the gate voltage is reduced. Third, the carbon nanotube cathode has a small fabrication area. The small area of the carbon nanotube cathode, i.e. the small number of carbon nanotubes, is very disadvantageous for forming a large cathode current of a light emitting backlight. These technical difficulties also need to be carefully considered and addressed.

Has the advantages that: the invention has the following remarkable progress:
firstly, in the gate control structure of the angled thorn circumferential double-connecting-surface cathode alternating oblique bow, a gate pole bow lower electrode, a gate pole bow middle electrode and a gate pole bow upper electrode are manufactured. On one hand, the gate pole bow-arc lower electrode, the gate pole bow-arc upper electrode and the gate pole bow-arc middle electrode act together, and the externally applied gate pole voltage can be smoothly transmitted to the surface of the carbon nano tube layer; on the other hand, the gate pole bow lower electrode, the gate pole bow middle electrode and the gate pole bow upper electrode can form strong electric field intensity on the surface of the carbon nano tube layer to force the carbon nano tube layer to emit electrons, and the number of the emitted electrons changes along with the change of the gate pole voltage, so that the regulation and control function of the gate pole voltage on the carbon nano tube layer is embodied. Moreover, the manufacturing shapes of the gate pole arch upper electrode, the gate pole arch middle electrode and the gate pole arch lower electrode enable the effective distance between the gate pole and the carbon nano tube cathode to be increased, electric field breakdown between the gate pole and the carbon nano tube cathode is not easy to occur, and the manufacturing yield of the light-emitting backlight source is greatly improved.
Secondly, in the cathode alternating oblique bow gate control structure with double connecting surfaces around the horn prick, a cathode horn prick outer electrode and a cathode horn prick inner electrode are manufactured. The cathode corner spine outer electrode is positioned on the outer side surface of the cathode spine base intermediate layer and surrounds the cathode spine base inner layer; the cathode horn spine inner electrode is positioned on the inner side surface of the cathode spine base middle layer and surrounds the cathode spine base inner layer. The cathode horn outer electrode and the cathode horn inner electrode both have large surface areas; after the carbon nanotube layer is manufactured on the cathode horn outer electrode and the cathode horn inner electrode, the manufacturing area of the carbon nanotube layer is effectively increased, that is, the number of the carbon nanotubes capable of performing electron emission is effectively increased, which is beneficial to further improving the adjustable performance of the light-emitting gray scale of the light-emitting backlight source and improving the light-emitting brightness of the light-emitting backlight source.
Thirdly, in the cathode alternating oblique bow gate control structure with double connecting surfaces around the horn prick, the carbon nano tube layer is manufactured on the cathode horn prick outer electrode and the cathode horn prick inner electrode. The cathode horn-spine outer electrode and the cathode horn-spine inner electrode both have large cathode edges, and after the carbon nanotube layer is manufactured on the cathode horn-spine outer electrode and the cathode horn-spine inner electrode, the carbon nanotubes at the edge positions can fully utilize the phenomenon of 'edge electric field enhancement' to emit more electrons; the cathode current of the luminescent backlight becomes large, which is extremely advantageous for increasing the cathode current of the luminescent backlight. Meanwhile, the cathode horn outer electrode and the cathode horn inner electrode both have good conductivity, and can provide required cathode potential for the carbon nano tube layer, so that the use power of the light-emitting backlight source can be further reduced.
In addition, no special manufacturing material is adopted in the light-emitting backlight source with the angled spine annular double-connected-surface cathode alternating oblique bow gate control structure, so that the manufacturing cost of the whole light-emitting backlight source is further reduced.
