Problems solved by technology

[0003] In most of the field emission display devices reported so far, the control mode in which the gate structure is located above the carbon nanotube cathode structure is adopted. The manufacturing process is relatively simple, but there are often high gate voltages, The display brightness of the device is not high, the anode operating current is too small and other shortcomings, and it is difficult to combine with the conventional integrated drive circuit
