The film morphology of screen‐printed carbon nanotube emitters was modified by using the liquid elastomer. The entangled carbon nanotube (CNT) bundles were broken up into individual free standing nanotubes to remarkably improve the field‐emission characteristics over the as‐deposited CNT film. In addition, the modification of the cathode film morphology of top‐gated triode type structures can be easily solved by using our based surface treatment technique, which is a low‐cost, simple process. This technique has showed good possibility for surface treatment of large‐size field emission displays (FEDs) in the future.
