Problems solved by technology

However, in the currently developed three-electrode structure field emission display, there are generally disadvantages such as high device manufacturing cost, complicated device manufacturing process, and high gate operating voltage, and the requirements for device manufacturing materials are relatively high. These disadvantages are hindering the research progress of field emission displays

However, there is no satisfactory solution for the fabrication process and structure of the carbon nanotube cathode, and a lot of research and development are still needed.
