Description

Light-emitting backlight source of circumferential doubly-connected concave cathode reinforced arc straight slope gate control structure
Technical Field
The invention belongs to the technical field of planar display, the technical field of nano science and nano technology, the technical field of vacuum science and vacuum technology, the technical field of microelectronic science and microelectronic technology, the technical field of integrated circuit science and microelectronic technology and the field of optoelectronic science and technology, and relates to the manufacture of a planar light-emitting backlight source, in particular to the manufacture of a planar light-emitting backlight source of a carbon nano tube cathode, in particular to a light-emitting backlight source of a circular-periphery doubly-connected concave cathode reinforced arc straight slope gate control structure and a manufacturing process thereof.
Background
The carbon nanotube is a nano-scale tubular material with good conductive performance, and can perform electron emission in a vacuum environment. A plurality of carbon nanotubes are fabricated together to form a carbon nanotube layer; the carbon nanotube layer can be applied to a vacuum component of a light-emitting backlight source and serves as a carbon nanotube cathode of the light-emitting backlight source, so that sufficient cathode current is provided for the light-emitting backlight source.
However, there are some technical difficulties to be solved in the light emitting backlight of the three-pole structure. First, the gate electrode has poor control over the electron emission from the carbon nanotube layer. For a lower gate voltage, the carbon nanotube layer does not emit electrons at all; for higher gate voltage, the carbon nanotube layer can emit electrons, but the emission amount of the carbon nanotube layer does not change with the change of the gate voltage. These are all embodiments where the gate has poor control over the electron emission from the carbon nanotube. And secondly, the manufacturing area of the carbon nanotube layer is smaller. The carbon nanotube layer is composed of a plurality of carbon nanotubes, and a large cathode current of the light-emitting backlight source cannot be formed without a carbon nanotube layer with enough manufacturing area, which is needless to say. Third, the electron emission efficiency of the carbon nanotube layer is very low. In the carbon nanotube layer, some carbon nanotubes can emit micro electrons and some carbon nanotubes can emit a large amount of electrons along with the formation of a strong electric field, but the carbon nanotubes with a large part do not emit electrons at all, which is a negative factor that the light-emitting backlight source cannot form a large cathode current. These technical difficulties require careful consideration and careful study.

Has the advantages that: the invention has the following remarkable progress:
firstly, in the circumferential double-connection concave cathode reinforced arc straight slope gate control structure, a gate arc straight lower electrode, a gate arc straight front electrode and a gate arc straight rear electrode are manufactured. The gate electrode arc straight lower electrode, the gate electrode arc straight front electrode and the gate electrode arc straight rear electrode are mutually crossed to manufacture the structure, so that the gate electrode is well manufactured, and the manufacturing yield of the light-emitting backlight source is improved. The gate electrode arc straight lower electrode, the gate electrode arc straight front electrode and the gate electrode arc straight rear electrode act together to ensure that the applied gate electrode voltage is smoothly transmitted to the surface of the carbon nano tube layer. And the gate pole arc straight lower electrode, the gate pole arc straight front electrode and the gate pole arc straight rear electrode are matched with each other, so that strong electric field intensity can be formed on the surface of the carbon nano tube layer, the control function of gate pole voltage on electron emission of the carbon nano tube layer is embodied, and the control method is extremely favorable for further enhancing the luminous brightness of the luminous backlight source.
Secondly, in the circumferential double-connection concave cathode reinforced arc straight slope gate control structure, a cathode connection concave lower electrode and a cathode connection concave upper electrode are manufactured. The cathode connecting concave lower electrode is positioned on the outer side surface of the cathode double-concave two-layer and surrounds the cathode double-concave two-layer; the cathode connecting concave upper electrode is positioned on the outer side surface of the cathode double concave three layers and surrounds the cathode double concave three layers. The manufacturing structure ensures that the cathode continuous concave lower electrode has a large surface area and also ensures that the cathode continuous concave upper electrode has a large surface area. After the carbon nanotube layer is simultaneously manufactured on the cathode connecting concave lower electrode and the cathode connecting concave upper electrode, the manufacturing area of the carbon nanotube layer is effectively increased, and thus the number of carbon nanotubes capable of performing electron emission is increased. The manufacturing structure is stable and reliable, and is beneficial to further improving the brightness of the light-emitting backlight and improving the adjustable performance of the light-emitting gray scale of the light-emitting backlight.
Thirdly, in the cathode reinforced arc straight slope gate control structure with the circumferentially doubly connected concave surface, the carbon nanotube layer is manufactured on the cathode connected concave lower electrode and the cathode connected concave upper electrode. After the cathode connecting concave lower electrode and the cathode connecting concave upper electrode are both provided with large cathode edges, and the carbon nanotube layer is simultaneously manufactured on the cathode connecting concave lower electrode and the cathode connecting concave upper electrode, the carbon nanotubes in the carbon nanotube layer can fully utilize the phenomenon of 'edge electric field enhancement', and can carry out more electron emission under the same gate voltage, so that the electron emission efficiency of the carbon nanotube layer is improved, and the method is also helpful for further improving the luminous brightness of the luminous backlight source.
In addition, no special manufacturing material is adopted in the light-emitting backlight source with the circumferential double-connection concave cathode reinforced arc straight slope gate control structure, so that the manufacturing cost of the whole light-emitting backlight source is reduced.
