Auxiliary interconnection in special-shaped arcs Silver-gated oblique hooks Cathode structure light-emitting display with concave tire surface

technical field

The present invention belongs to the fields of display technology, nanometer science and technology, optoelectronic science and technology, microelectronics science and technology, integrated circuit science and technology, and vacuum science and technology, and relates to a flat field emission display The manufacture specifically relates to the manufacture of a planar field emission luminescent display of a carbon nanotube cathode, and particularly relates to a display and a manufacturing process of a luminescent display with an auxiliary interconnected silver-gated oblique hook concave tread cathode structure in a special-shaped arc.

Background technique

Carbon nanotubes are a very good source of cold cathode electrons. In a vacuum environment, they can continuously provide cathode electrons for the field emission luminescence display in the form of "field emission", thus forming the necessary conditions for the normal operation of the field emission luminescence display. required current. In the field emission light-emitting display of the triode structure, the gate structure is added between the anode and the carbon nanotube cathode. In view of the close distance between the gate and the carbon nanotube cathode, a very low gate voltage can form the electric field strength required for carbon nanotube field electron emission. This is very beneficial for reducing the power loss of the field emission light-emitting display and reducing the cost of the driving circuit of the field emission light-emitting display. However, with the successful introduction of the gate structure, many technical difficulties have been brought to the field emission light-emitting display with the three-electrode structure. For example, first, the control performance of the gate. When an appropriate voltage is applied to the gate, the carbon nanotubes cannot conduct field electron emission, which indicates that the fabricated gate structure does not work at all; when an appropriate voltage is applied to the gate, although the carbon nanotubes conduct Field electron emission is achieved, but the number of emitted electrons does not change with the gate voltage, which also shows that the control ability of the fabricated gate structure is poor. This is related to the manufacturing structure and manufacturing process of the gate electrode, which needs to be considered comprehensively. Second, the integrated fabrication of carbon nanotube cathodes and gates. Since the distance between the gate and the carbon nanotube cathode is very small, the fabrication structures of the two must influence each other. When making the subsequent structure, it is easy to cause damage to the previous structure; in addition, the carbon nanotube layer is thin-layered, which is very easy to be damaged and polluted, so it is necessary to integrate the two structures of the carbon nanotube cathode and gate production, the degree of their mutual influence must be reduced, or the mutual influence between the two must be completely eliminated. Once the carbon nanotube layer is damaged or polluted, the ability to emit electrons will decrease, which will cause the complete failure of the field emission display. Third, the fabrication of carbon nanotube layers. In order to improve the image quality of the field emission light-emitting display as much as possible, it is necessary to allow the carbon nanotube layer to provide as many electrons as possible. However, among the currently produced carbon nanotube cathodes, the number of carbon nanotubes capable of effective field electron emission is very small, and even a large number of carbon nanotubes cannot emit electrons at all. Since the number of electrons provided by carbon nanotubes is very small, it is impossible to improve the image quality of field emission light-emitting displays. The technical problems mentioned above are not isolated, and require comprehensive research and development from all aspects of production structure, production process, and production process. In addition, the production cost of the field emission light-emitting display is also one of the things that must be taken into consideration. An overly expensive field emission light-emitting display cannot meet the actual product demand of the display technology market.

Beneficial effects: the present invention has the following remarkable progress:

First, in the special-shaped inner-arc auxiliary interconnection silver-gated silver-gated oblique hook concave tread cathode structure, a special-shaped inner-arc auxiliary interconnection silver gate is fabricated. In the special-shaped arc inner auxiliary interconnection silver gate, the upper layer of the gate electrode with different arc auxiliary electrode in planar shape and the lower layer of the gate electrode with different arc auxiliary electrode in the shape of downward concave arc surface play the main control carbon nanotube layer electron emission, and the rear end of the upper layer of the gate differential arc auxiliary electrode is connected to the rear end of the lower layer of the gate differential arc auxiliary electrode. When an appropriate voltage is applied to the gate, a strong electric field can be formed on the surface of the carbon nanotube layer, thereby forcing the carbon nanotube to emit a large number of electrons; with the change of the gate operating voltage, the carbon nanotube cathode provides The number of electrons will also change accordingly. This reflects the strength regulation performance of the auxiliary interconnection silver gate in the special-shaped arc. Between the upper layer of the gate differential arc auxiliary electrode and the lower layer of the gate differential arc auxiliary electrode, the front layer of the gate differential arc auxiliary electrode and the middle rear layer of the gate differential arc auxiliary electrode are fabricated, and the middle layer of the gate differential arc auxiliary electrode is The front layer connects the two with each other, and the rear layer in the gate differential arc auxiliary electrode also connects the two with each other. On the one hand, it plays the role of assisting in regulating the electron emission of the carbon nanotube layer, and on the other hand, it also plays the role of more smoothly transmitting the gate potential. It is very helpful for improving the luminous brightness of the field emission luminescent display, improving the luminous gray scale adjustability of the field emission luminescent display, and shortening the response time.

Secondly, in the special-shaped arc internal auxiliary interconnection silver-gated oblique hook concave tread cathode structure, the two structures of special-shaped arc internal auxiliary interconnection silver gate and oblique hook concave tire tread cathode are integrated. In the production process, the production process of the auxiliary interconnected silver gate in the special-shaped arc and the production process of the oblique hook concave tire surface cathode are used to intersect with each other. The production process is the last process. In this way, it can not only ensure the smooth and successful fabrication of the auxiliary interconnected silver gate structure in the special-shaped arc, but also ensure the smooth completion of the fabrication of the oblique hook concave tread cathode structure, and ensure that the carbon nanotube layer is prepared without any damage. This helps to improve the production yield of the field emission light emitting display and reduce the production cost of the field emission light emitting display.

Thirdly, in the special-shaped arc internal auxiliary interconnection silver-gated oblique hook concave tire tread cathode structure, the oblique hook concave tire tread cathode is fabricated. The junction line between the upper end of the cathode concave transfer layer and the outer end of the curved surface of the cathode marginal layer is a circular line, and the lower end of the cathode concave transfer layer is a ring-like linear shape with an inwardly concave trapezoidal gap, and the carbon nanotube layer is prepared on the cathode concave transfer layer. That is to say, the inclined hook concave tire tread cathode has a large electrode edge. On the basis of making full use of the "edge electric field enhancement" phenomenon in the field emission luminescence display, the carbon nanotubes at the edge of the electrode can emit more electrons, which is helpful for improving the luminous brightness of the field emission luminescence display and improving the field emission luminescence. The luminous gray scale adjustability of the display is very beneficial.
