Problems solved by technology

In this case, an additional circuit is required for electrical adjustment. It is expected that a slightly higher voltage will be applied to the cathode of the carbon nanotubes with relatively weak luminous brightness to emit more electrons, which will increase the luminous brightness of the pixel, and let the luminous The voltage on the carbon nanotube cathode with relatively strong brightness is slightly lowered, reducing the brightness of the pixel
However, there is no perfect solution to such problems
