We describe a transfer printing method for patterning of thin polymer layers. A hard stamp with raised feature is brought into contact with a spin coated organic film under elevated pressure and temperature to break the films. The patterned film is then transfer printed onto devices. We use this method to print red/green/blue sub‐pixel arrays with pattern size as small as 12 μm at a resolution of 530 ppi to demonstrate its ability for full‐color organic light‐emitting display fabrication.
