A novel corrugated substrate has been developed for OLED lighting applications. The substrate enhances the light extraction efficiency without changing the spectra or luminous intensity distributions due to its self‐assembled quasi‐periodic structure. By combining the corrugated substrate with a specially designed lens array, a 102% improvement in power efficiency was achieved in a large area light‐emitting device.
