Organic Light‐Emitting Diodes: Organic Light‐Emitting Diodes: Pushing Toward the Limits and Beyond (Adv. Mater. 35/2020)

Abstract

Recent advances in highly efficient organic light-emitting diodes (OLEDs) and their emerging applications, including phototherapeutic patches, biometric sensors, and textile displays are reviewed by Kyung Cheol Choi, Seunghyup Yoo, and co-workers in article number 1907539. For efficiency improvement, the importance of outcoupling structures coupled with horizontally oriented dipole emitters is highlighted.
