Problems solved by technology

After the addition of the gate structure has become an inevitable choice, the negative problems caused by the gate structure cannot be ignored. For example, the gate voltage in the current display device is still high, and the gate structure will intercept some electrons to form a gate. Current, the control effect of the gate is not significant and the electron emission efficiency of the carbon nanotube cathode is low, etc. need to be solved
