The invention has the advantages of low cost, simple structure, high making yield, stable and reliable lower grid structure.

Description

technical field [0001] The invention belongs to the intercrossing fields of nanometer science and technology, flat panel display technology and vacuum science and technology, and relates to the production of flat field emission light-emitting display devices, and specifically relates to the content of the device production of flat field emission display devices of carbon nanotube cathodes The invention relates in particular to a manufacturing process of a field emission flat display device with a lower gate structure and a carbon nanotube cathode. Background technique [0002] For the most part, people rely on some form of display to communicate with their computer systems. Flat-panel displays are the fundamental display component of devices ranging from the dashboard indicator dials of cars to the high-definition displays of high-end laptops. Compared with ordinary CRT monitors, flat panel monitors have many advantages, such as small footprint, thinness, high image display...

AI Technical Summary

Problems solved by technology

At present, most of the flat-panel displays have chosen the structure type in which the control grid is located above the carbon nanotube cathode, which has the characteristics of simple manufacturing structure, strong control function, and simplified manufacturing process, but the formed grid current is relatively large. The requirements for the insulating material of the device are relatively high, and because the materials for making the control gate are different, some special manufacturing processes are used, resulting in an increase in the overall cost of the device and the inability to make large-area production. These are its disadvantages
