A universal strategy for highly power‐efficient white organic light‐emitting diodes is developed by Y.‐Q. Li, J.‐X. Tang, and colleagues on page 7249 by combining deterministic aperiodic nanostructures for broadband quasi‐omnidirectional light extraction and a multilayer energy cascade structure for energy‐efficient photon generation. A record efficiency exceeding 120 lm W −1 is achieved with an extremely small roll‐off in efficiency and superior angular color stability.
