Description

Light-emitting backlight source of arrow-penetrating, bending-stabilizing and gating structure with same-circle drum pair-broken arc-surface cathode
Technical Field
The invention belongs to the fields of semiconductor science and technology, nano science and technology, vacuum 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 sources, in particular to the manufacture of a plane light-emitting backlight source of a carbon nano tube cathode, in particular to a light-emitting backlight source of a same-circle drum opposite-broken arc-surface cathode arrow-penetrating stable-bending gate control structure and a manufacture process thereof.
Background
The carbon nanotube is a hollow tubular substance with the pipe diameter in the nanometer order. Due to its small tip radius of curvature, it is capable of a large amount of electron emission under a suitable vacuum environment. The excellent electrical characteristics of carbon nanotubes can be fully utilized to form electron sources for devices. In a light emitting backlight, electrons emitted by the carbon nanotubes may be used to form a cathode current of the light emitting backlight. However, in a light-emitting backlight of a three-pole structure, there are some technical difficulties to be overcome. First, the carbon nanotubes emit a low number of electrons, making it difficult to form a large cathodic current. In the carbon nanotube layer, there are many carbon nanotubes, but not all of the carbon nanotubes participate in electron emission. Only a small fraction of the carbon nanotubes are capable of electron emission and the number of electrons emitted is not large, and the cathode current of a luminescent backlight is mainly derived from these emitted cathode electrons. Since the number thereof is not large, the cathode current of the light emitting backlight is also small. While most of the carbon nanotubes do not emit electrons, forming a virtually ineffective cathode. In carbon nanotube cathodes, the presence of ineffective cathodes should be minimized. Second, the control of the gate voltage to the carbon nanotube cathode is weak. When a proper gate voltage is applied, the carbon nanotube does not emit electrons immediately, and generally delays for a period of time; when the gate voltage is removed, the carbon nanotubes still emit electrons. These are all specific manifestations of gate voltage runaway. There is also a need for improvements in gates. These technical difficulties also require careful and comprehensive consideration and search.
