Description
Technical Field
The invention belongs to the fields of nano science and technology, microelectronic science and technology, integrated circuit science and technology, vacuum science and technology, semiconductor science and technology, flat display technology and the field of mutual intersection of photoelectron science and technology, and relates to the manufacture of a flat field emission light-emitting display, in particular to the manufacture of a flat field emission light-emitting display with a carbon nano tube cathode, in particular to a light-emitting display with an asymmetric double-slow side arc hollow ring surface cathode conjunction inclination angle gate control structure.
Background
A field emission light emitting display is a novel display device, has excellent characteristics such as high brightness, high definition, high resolution, ultra-thin type, and wide applicable temperature range, and has attracted much attention from many researchers. The inside of the field emission light emitting display is a vacuum environment, and the carbon nanotubes are used as cathode materials, and by applying a proper working voltage, the carbon nanotubes are forced to emit electrons to form a cathode current, so that an image is displayed. The gate electrode is made by controlling whether the carbon nanotube cathode emits electrons or not and the quantity of the emitted electrons.
However, there are many technical problems to be solved in the field emission light emitting display of the triode structure. For example, the carbon nanotube layer in the field emission light-emitting display is fabricated with a small area, which means that the number of carbon nanotubes is reduced; the carbon nanotubes with insufficient amount for electron emission cannot form large cathode current, and the technical indexes of the light emitting display, such as improvement of the light emitting brightness, adjustability of the light emitting gray level, and the like, cannot be improved and adjusted. For example, in a field emission display, although a gate electrode is fabricated on the upper portion of a carbon nanotube cathode, the control of the gate electrode on the carbon nanotube cathode is weak, and after a gate voltage is applied, some carbon nanotubes emit a small amount of electrons, even many carbon nanotubes do not emit electrons at all, and even if a small amount of carbon nanotubes emit a large amount of electrons, the cathode current formed by the carbon nanotubes is very weak; under the phenomenon, performance indexes of the field emission light-emitting display such as video color diversification and light-emitting gray scale adjustability cannot be optimized. For another example, the carbon nanotubes of a field emission light-emitting display have low electron emission efficiency, and even though a large gate voltage is applied, the carbon nanotubes still cannot provide enough emitted electrons; the larger the number of carbon nanotubes can be provided, the more it is helpful to form a large cathode current for a field emission light-emitting display. These technical problems need to be solved by considering various factors such as the manufacturing structure and the manufacturing process.

Has the advantages that: the invention has the following remarkable progress:
firstly, in the asymmetric double-slow-side arc hollow ring surface cathode conjunction inclination angle gating structure, carbon nano tubes are simultaneously prepared on the outer layer of the cathode ring body and the inner layer of the cathode ring body to form a carbon nano tube layer. The upper edge of the outer layer of the cathode ring body is in a slow arc ring shape, the upper edge of the inner layer of the cathode ring body is also in a slow arc ring shape, and the curvature change of the electric field intensity is larger at the upper edges of the outer layer of the cathode ring body and the inner layer of the cathode ring body, namely the electric field intensity at the position is more concentrated; after the carbon nanotubes are prepared on the outer layer and the inner layer of the cathode ring body, the carbon nanotubes in the position will emit a large amount of electrons under the force of strong electric field intensity. The more electrons provided by the carbon nanotubes, the larger the current of the field emission light-emitting display, which is very helpful for providing the light-emitting brightness of the field emission light-emitting display.
Secondly, in the asymmetric double-slow-side arc empty ring surface cathode conjunction inclination angle gating structure, carbon nanotube layers are manufactured on the outer layer of the cathode ring body and the inner layer of the cathode ring body electrode. Therefore, the area of the carbon nano tube layer is effectively enlarged under the restriction of the limited cathode area. The enlargement of the area of the carbon nanotube layer, that is, the increase of the number of carbon nanotubes capable of electron emission, is very helpful to improve the adjustability of the light gray scale of the field emission light emitting display and further enhance the video color diversification of the field emission light emitting display.
Thirdly, in the asymmetric double-slow side arc hollow annular surface cathode conjunction inclination angle gate control structure, a conjunction inclination angle gate control structure is manufactured. The gate electrode silver-gray outer wire layer has the function of smoothly transmitting the external potential to the surface of the carbon nano tube, and the upper layer of the gate electrode connecting angle electrode and the lower layer of the gate electrode connecting angle electrode are jointly responsible for regulating and controlling the electron emission of the carbon nano tube layer. After a proper gate voltage is applied, a strong electric field intensity is formed on the surface of the carbon nano tube, so that the carbon nano tube is forced to emit a large number of electrons, and the control function of the gate on the carbon nano tube is embodied. Meanwhile, due to the arc-shaped structures of the upper layer of the gate connecting angle electrode and the lower layer of the gate connecting angle electrode, the effective distance between the gate and the cathode is increased, and the electric field breakdown phenomenon between the gate and the cathode is not easy to occur.
In addition, in the asymmetric double-slow-side arc empty ring surface cathode conjunction inclination angle gating structure, a special manufacturing process is not adopted, so that the manufacturing yield of the light-emitting display is further improved; and no special manufacturing material is adopted, which contributes to further reducing the manufacturing cost of the light-emitting display and lightening the performance requirement on the manufacturing material.
