Problems solved by technology

With the increase of the display area in the display device, the number of corresponding carbon nanotube cathodes increases geometrically. Then, in such a large number of carbon nanotube cathodes, it is difficult to ensure that all carbon Nanotube cathodes all have the same field emission capability, and it is difficult to ensure that the phosphor layer corresponding to the carbon nanotube cathode emits the same intensity of visible light; because the luminance of different phosphor pixels may be different, it also causes display devices poor display image quality
