Problems solved by technology

For carbon nanotube cathodes with similar distances, due to the influence of external factors, the luminescence degree of the corresponding phosphors may also be different, which requires additional electrical adjustments, hoping to make carbon nanotubes with weaker luminance A slightly higher voltage is applied to the cathode to emit more electrons and increase the brightness of the pixel, while the voltage on the carbon nanotube cathode with a relatively high luminance is slightly lower to reduce the brightness of the pixel

However, there is no perfect solution to such problems
