Polymer encapsulation of flexible top-emitting organic light-emitting devices with improved light extraction by integrating a microstructure

- A polymer encapsulation film integrated with microstructure has been developed for the FTOLED.
- The total reflection has been suppressed by the microstructured surface.
- The light extraction of the FTOLED has been improved by the suppressed total reflection.
- The microstructured surface exhibits a hydrophobic property.
- A self-cleaning ability for the FTOLED has been obtained by the hydrophobic surface.
