Problems solved by technology

In the current research and development of the three-electrode structure field emission display, there is no satisfactory production plan for the production process and production structure of the carbon nanotube cathode. Different researchers have different production methods, but none of them can reach the optimum As for the gate structure, there are not only disadvantages such as too strict requirements on the gate material, but also defects such as too complicated fabrication process of the gate structure, which are not conducive to field emission flat panel displays. For the overall device, there are generally disadvantages such as high gate operating voltage and large gate operating current, which obviously do not conform to the principle of low-voltage flat panel devices, and further research and improvement are needed
