technical field

The present invention belongs to the fields of plane display technology, nanometer science and technology, integrated circuit science and technology, microelectronics science and technology, optoelectronics science and technology, semiconductor science and technology, and vacuum science and technology. The invention relates to the manufacture of a plane light-emitting backlight source, in particular to the manufacture of a plane light-emitting backlight source of carbon nanotube cathodes, and in particular to a light-emitting backlight source with an alternate oblique arch gated structure of angle thorn ring and double-connected plane cathodes and a manufacturing process thereof.

Background technique

In a suitable vacuum environment, carbon nanotubes can emit electrons, which makes carbon nanotubes a very suitable cathode material. With the large-scale promotion of the screen printing process, it becomes easy to fabricate large-area, patterned carbon nanotube cathodes, which also accelerates the fabrication process of carbon nanotube cathodes. The light-emitting backlight made of carbon nanotube cathodes is a kind of vacuum equipment; the accelerated development of carbon nanotube cathodes undoubtedly promotes the research progress of light-emitting backlight devices.

However, in the light-emitting backlight of the tri-pole structure, there are still 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 only emit less electrons, and even a considerable part of carbon nanotubes do not emit electrons at all Therefore, in general, the electron emission efficiency of the carbon nanotube cathode is very low, and it is also very unfavorable to form a large cathode current of the light-emitting backlight. Second, the regulation performance of the gate voltage on the CNT cathode is very poor. The function of the gate voltage is to control and adjust the electron emission of the carbon nanotube cathode, so that the number of electrons emitted by the carbon nanotube cathode can change with the change of the gate voltage; if the electron emission of the carbon nanotube cathode is not Strictly with the change of the gate voltage, it means that the control performance of the carbon nanotube cathode by the gate voltage is weakened. Third, the fabrication area of carbon nanotube cathodes is very small. The fabrication area of the carbon nanotube cathode is small, that is to say, the number of carbon nanotubes is reduced, which is very unfavorable for forming a large cathode current of the light-emitting backlight. These technical difficulties also need careful consideration and resolution.

Beneficial effect: the present invention has following remarkable progress:

First, in the alternate oblique arch gate structure of the present invention, the lower electrode of the gate bow, the middle electrode of the gate bow and the upper electrode of the gate bow are fabricated. On the one hand, the lower electrode of the gate bow, the upper electrode of the gate bow and the middle electrode of the gate bow work together, and can smoothly transfer the externally applied gate voltage to the surface of the carbon nanotube layer; on the other hand, the gate bow The under-arc electrode, the gate bow middle electrode and the gate bow upper electrode can form a strong electric field on the surface of the carbon nanotube layer, forcing the carbon nanotube layer to emit electrons, and the number of electron emission varies with the gate voltage. changes, thus reflecting the regulation function of the gate voltage on the carbon nanotube layer. Furthermore, the fabrication shapes of the upper electrode of the gate bow, the middle electrode of the gate bow, and the lower electrode of the gate bow increase the effective distance between the gate and the carbon nanotube cathode, so that the electric field between the two is increased. The breakdown phenomenon is not easy to occur, which greatly improves the manufacturing yield of the light-emitting backlight.

Secondly, in the gating structure of the present invention, an outer electrode of the cathodic horn and an inner electrode of the cathodic horn are fabricated in the gating structure of the present invention. The cathodic angle thorn outer electrode is located on the outer side of the cathode thorn base intermediate layer and surrounds the cathode thorn base layer; the cathode horn thorn inner electrode is located on the inner side of the cathode thorn base intermediate layer and surrounds the cathode thorn base layer Floor. Both the cathodic horn outer electrode and the cathodic horn inner electrode have large surface areas; when the carbon nanotube layer is fabricated on the cathodic horn outer electrode and the cathodic horn inner electrode, the fabrication area of the carbon nanotube layer is also effective. It means that the number of carbon nanotubes capable of electron emission is effectively increased, which is beneficial to further improving the luminous grayscale adjustment performance of the light-emitting backlight and improving the light-emitting brightness of the light-emitting backlight.

Third, in the gating structure of the present invention, the carbon nanotube layer is fabricated on the outer electrode of the thorn and the inner electrode of the thorn. Both the cathode horn outer electrode and the cathodic horn inner electrode have a large cathode edge. When the carbon nanotube layer is fabricated on the cathode horn outer electrode and the cathode horn inner electrode, the carbon nanotubes in the edge position can be Make full use of the phenomenon of "fringe electric field enhancement" to carry out more electron emission; then the cathode current of the light-emitting backlight will become larger, which is extremely beneficial for increasing the cathode current of the light-emitting backlight. At the same time, both the cathode horn outer electrode and the cathode horn inner electrode have good electrical conductivity, which can provide the required cathode potential for the carbon nanotube layer, which also helps to further reduce the usage power of the light-emitting backlight.

In addition, in the light-emitting backlight with the alternate slanted bow gated structure of the corner thorn ring and the double-plane cathode alternately, no special manufacturing materials are used, which helps to further reduce the manufacturing cost of the overall light-emitting backlight.
