Zusammenfassung:On page 3454, Franky So and co‐workers report the preparation of defective hexagonal‐close‐packed arrays to extract the waveguide modes trapped in an organic light‐emitting diode. The broadening of the periodicity and the lack of long‐range ordering in the defective array pattern allow effective extraction of the waveguide modes over all emission wavelengths and angles, resulting in non‐directional light emission with insignificant spectral changes.
