AI Technical Summary

Problems solved by technology

However, in the display devices currently developed, there are certain limiting factors for the gate material and fabrication process, which lead to excessive gate operating voltage and excessive gate current, which not only cannot meet the requirements of low voltage and low cost. The requirements of flat panel devices, but also force the production cost of the device to remain high

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.
