Photolithography offers a scalable solution for large area pixel patterning of organic light‐emitting diode (OLED) displays. It has been limited due to the incompatibility of traditional processing steps with the majority of organic materials. In this work, photolithographic structuring of state‐of‐the‐art phosphorescent red p‐i‐n OLEDs is demonstrated using fluorinated polymers in combination with hydrofluoroether solvents. This is the first report on photolithographically patterned OLEDs with state‐of‐the‐art efficiency and good long‐term stability.
