AI Technical Summary

Problems solved by technology

With this technique, it is difficult to deposit nano-luminescent elements biased in the same direction in each pixel
Therefore, there is a problem that the nano light-emitting element biased in the reverse direction may not be able to emit light by the DC drive of the pixel, thereby reducing the luminous efficiency
