摘要

We demonstrate a broad-bandwidth and viewing-angle independent white emission from top-emitting organic light-emitting devices (TOLEDs) by integrating a microstructured cavity with a periodically and gradually changed cavity length. The results indicate that the microstructured cavity can resolve the viewing angle-dependence effect persisted in the conventional planar TOLEDs. The viewing-angle independence in both broad-band emission spectra and Commision Internationale de L'Eclairage coordinates are obtained. Moreover, the microstructured white TOLEDs show comparable luminance and current efficiency to that of the planar TOLEDs.
