Problems solved by technology

At present, in most flat panel display devices, the gate structure is located above the carbon nanotube cathode. The strong control effect of the gate structure is obvious, but the formed gate current is relatively large, and the gate control voltage is relatively high. , the requirements for the material of the device are relatively high, and the carbon nanotube cathode is easy to be polluted and damaged during the manufacturing process of the device, which is its disadvantage

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...
