Abstract
Description
technical field
[0001] The invention belongs to the fields of plane display technology, microelectronic science and technology, vacuum science and technology, and nano science and technology, and relates to the manufacture of flat panel field emission displays, in particular to flat panels for carbon nanotube cathodes. The content of device fabrication of field emission display, especially related to the fabrication process of field emission flat panel display device with integrated back gate structure and carbon nanotube cathode. Background technique
[0002] Carbon nanotubes have small tip curvature radius, high aspect ratio, extremely high mechanical strength and good physical and chemical properties, and are an ideal cold cathode material. At present, the preparation methods for carbon nanotube cathodes can be roughly divided into two types, namely: direct growth method and transplantation method. The field emission characteristics of carbon nanotube cathodes prepared b...
