Embodiment Construction

[0025] Such as figure 1 , 2 , 3, and 4, in order to understand and demonstrate the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the present invention is not limited to these embodiments.

[0026] The present invention provides a manufacturing process of carbon nanotube cathode material, including the following manufacturing steps:

[0027] 1. Scribing of the cathode substrate glass (1): Scribing the whole flat glass;

[0028] 2. The making of the cathode conductive strip (2): vapor-depositing a layer of tin-indium oxide thin film layer on the cathode base glass (1); photolithography is carried out to the evaporated tin-indium oxide thin-film layer to form the cathode conductive strip (2) );

[0029] 3. Preparation of carbon nanotube powder materials: Purify carbon nanotube powder, remove impurities in the powder, and carry out discrete work of large groups of carbon n...

Abstract

This invention relates to ultraviolet irradiation and wire printing combination to process the process of carbon nanometer tube and to make the nanometer plasm to process the nanometer negative pattern.

Description

technical field [0001] The invention belongs to the fields of vacuum science and technology, nano science and technology and microelectronics science and technology, and relates to a preparation process for directionally transplanting carbon nanotube materials to the surface of a substrate as a field emission cathode material, in particular to a A fabrication process for producing large-area carbon nanotube cathodes by combining ultraviolet light irradiation and screen printing. Background technique [0002] At present, for the field emission flat panel display devices manufactured by using carbon nanotubes as cathode materials, the cathode manufacturing processes are various and different. [0003] The field emission characteristics of carbon nanotube cathodes prepared by the growth process are better than those of carbon nanotube cathodes prepared by other transplantation methods, and can provide larger field emission currents, and the orientation and uniformity of carbon ...
