Problems solved by technology

At present, most displays use a control structure in which the gate is located above the carbon nanotube cathode. The manufacturing process of this control structure is relatively simple, and the control effect of the gate is obvious, but the formed gate current is relatively large. The material requirements are relatively high, which is its disadvantage
