Problems solved by technology

For example, regarding the effective distance between the gate and the carbon nanotube cathode, if the distance is too large, it will easily lead to an increase in the operating voltage of the gate, which will invisibly increase the power loss of the light-emitting display; if the distance is too small, it will easily cause the gate - The occurrence of electrical breakdown of the cathode causes permanent damage to the light-emitting display; at the same time, the insulation of the gate-cathode insulation material must also be considered. Without an insulation material with good insulation performance, it is impossible to connect the gate and the carbon nanotube cathode. made in isolation
