Technical Field

The invention belongs to the field of semiconductor science and technology, nano science and technology, integrated circuit science and technology, microelectronic science and technology, plane display technology, photoelectron science and technology, and the field of vacuum science and technology, and relates to the manufacture of plane light-emitting backlight, in particular to the manufacture of a plane light-emitting backlight with a carbon nano tube cathode, in particular to a light-emitting backlight with a cut-off staggered inclined ridge simple surface cathode leaning different curved gate control structure and a manufacture process thereof.

Background

The carbon nanotube cathode has excellent electron emission characteristics, and can be applied to light-emitting backlight source components to provide cathode current for the light-emitting backlight source. Since the carbon nanotube has an extremely high mechanical strength, the carbon nanotube can withstand processes such as printing, grinding, and the like without being damaged. Researchers have conducted extensive research and study in the field of pattern preparation of carbon nanotube cathodes, and the like. However, in the light emitting backlight of the three-pole structure, the following technical problems are still to be overcome. First, the gate electrode has poor control over the electron emission from the carbon nanotube cathode. The gate electrode is added to enhance the control of the electron emission of the carbon nanotube cathode, which is also the essential role of the gate electrode. The gate has many manifestations of runaway phenomena on carbon nanotube cathodes, such as: when a smaller gate voltage is applied, the carbon nanotube cathode does not emit electrons at all; after the carbon nano tube carries out electron emission, the cathode of the carbon nano tube does not stop the electron emission along with the removal of the gate voltage; and so on. The gate setting is meaningless unless the gate voltage is avoided and effective measures are taken for the carbon nanotube cathode out of control. Second, the electron emission of the carbon nanotube cathode is very non-uniform. In the same carbon nanotube layer, some carbon nanotubes emit electrons, but most of the carbon nanotubes do not emit electrons, so that the electron emission density of the carbon nanotubes is quite unbalanced; the electron emission currents of different carbon nanotube layers are not exactly the same, and some of the cathode currents are larger and some of the cathode currents are smaller. The above technical problem needs to be seriously explored.

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

firstly, in the gap-cut oblique ridge simple surface cathode-dependent hetero-curved gate control structure, a gate hetero-curved front electrode and a gate hetero-curved rear electrode are manufactured. The gate electrode differential-bending front electrode and the gate electrode differential-bending rear electrode are both made of silver layers, have good conductivity and can smoothly transfer gate electrode potential to the surface of the carbon nano tube. Meanwhile, the gate electrode differential-curvature front electrode and the gate electrode differential-curvature rear electrode act together to promote the carbon nano tube cathode to emit a large amount of electrons, thereby embodying the powerful control effect of the gate electrode on the carbon nano tube cathode. This is very advantageous for increasing the luminance of a luminescent backlight.

And secondly, manufacturing a cathode simple plane flat electrode and a cathode simple plane offset electrode in the staggered inclined ridge simple plane cathode-dependent differential curved gate control structure. The cathode simple plane flat electrode has a large surface area, and the cathode simple plane bias electrode also has a large surface area. That is to say, the manufacturing of the cathode simple plane flat electrode and the cathode simple plane offset electrode greatly expands the manufacturing area of the carbon nanotube layer, so that more carbon nanotubes participate in electron emission. This is extremely helpful to further improve the emission gradation adjustability of the emission backlight.

Thirdly, in the staggered oblique ridge simple surface cathode-dependent differential curved gate control structure, the carbon nanotube layer is manufactured on a cathode simple surface flat electrode and a cathode simple surface bias electrode. The cathode simple plane flat electrode has a large cathode edge, the cathode simple plane bias electrode also has a large cathode edge, and the carbon nano tube positioned at the cathode edge can emit more electrons, thereby being beneficial to improving the luminous brightness of the luminous backlight source and improving the luminous gray scale adjustability of the luminous backlight source.

In addition, no special manufacturing material is adopted in the light-emitting backlight source with the staggered-cutting inclined ridge simple-surface cathode leaning different-curve gating structure, so that the manufacturing cost of the whole light-emitting backlight source is reduced.
