On page 203, Y.‐Q. Li, S. Shen, J.‐X. Tang, and co‐workers demonstrate a wavelength‐independent light extraction scheme using nanoimprinted biomimetic quasi‐random nanostructures to simultaneously enhance light out‐coupling without color distortion and minimize the ohmic losses for multicolored, flexible organic LEDs. A superior color stability over the whole visible light range for wide viewing angles is realized due to the broad periodicity distribution and randomized emission directionality.
