Background

Carbon nanotubes are hollow tubes with excellent properties, have extremely high mechanical strength, and are used in many fields. One notable application is in the fabrication of cathode materials. In a light emitting backlight, carbon nanotubes can be used to provide the electron current needed for the operation of the light emitting backlight to form an electron source. Of course, the electric field required for electron emission from carbon nanotubes comes from an externally applied operating voltage. However, there are some technical problems to be overcome in the light emitting backlight of the carbon nanotube cathode with the triode structure. First, the control capability of the gate voltage of the light-emitting backlight source on the carbon nanotube cathode is poor. After the gate voltage is applied, the carbon nanotube cathode does not emit electrons at all, or the carbon nanotube cathode does emit electrons but is not further restricted by the gate voltage. These conditions exist such that the gate voltage has lost its essential role. In addition, in the carbon nanotube cathode, only a small part of the electron emission of the carbon nanotube can be controlled by the gate voltage, and other carbon nanotube cathodes are separated from the regulation of the gate voltage; the presence of the gate voltage is then of little significance as a whole. Second, the electron emission capability of the carbon nanotube cathode is low. Most of the carbon nanotubes are incapable of providing cathode electrons for a light-emitting backlight source under the same electric field strength; in a few carbon nanotubes capable of electron emission, the number of emitted electrons is not large. Therefore, the carbon nanotube cathode can supply a relatively small cathode current to the light emitting backlight as a whole. Third, the small carbon nanotube cathode fabrication area is also a non-negligible problem. In the face of these technical difficulties, there is also a constant effort required from researchers.

Has the advantages that: the invention has the following remarkable progress:

firstly, in the gate control structure of the cathode continuous depression surface of the serial peripheral ring rocking sector, a cathode serial ring lower electrode and a cathode serial ring upper electrode are manufactured. The cathode serial ring lower electrode and the cathode serial ring upper electrode both have good electric conduction capability and can transfer cathode potential to the carbon nano tube layer. Meanwhile, the surface areas of the cathode serial ring lower electrode and the cathode serial ring upper electrode are large, so that the surface area of the carbon nano tube layer manufactured on the cathode serial ring lower electrode and the cathode serial ring upper electrode is increased at the same time, and the improvement of the light-emitting uniformity of the light-emitting backlight source is very helpful.

Secondly, in the gate control structure of the cathode continuous depression surface of the serial connection peripheral ring rocking sector, a carbon nanotube layer is simultaneously manufactured on a cathode serial ring lower electrode and a cathode serial ring upper electrode. The lower electrode of the cathode serial ring has a large cathode edge, and similarly, the upper electrode of the cathode serial ring also has a large cathode edge; the electric field at the cathode edge increases dramatically, forcing the carbon nanotubes to emit an increased number of electrons, resulting in a large cathode current for the light emitting backlight. This is beneficial for improving the luminance of the light-emitting backlight and enhancing the uniformity of the light emission of the light-emitting backlight.

Thirdly, a gate pole bottom depressed surface electrode and a gate pole top depressed surface electrode are manufactured in the serial connection peripheral ring swing sector cathode double depressed surface gate control structure. The bottom depression surface electrode of the gate electrode and the top depression surface electrode of the gate electrode act together, so that the electron emission of the carbon nano tube cathode can be ensured, and the essential function of the gate electrode is embodied. Meanwhile, the simple manufacturing structures of the gate bottom depression surface electrode and the gate top depression surface electrode are also beneficial to improving the manufacturing yield of the light-emitting backlight source.

In addition, no special manufacturing material is adopted in the light-emitting backlight source with the serial connection peripheral ring rocking sector cathode continuous depression face gate control structure, so that the manufacturing cost of the whole light-emitting backlight source is reduced.
