Deskripsi
Light extraction approaches based on a macroscopic lens in organic light-emitting diodes (OLEDs) enables competitive performance, but compromise on the technology’s key benefits. Here, the authors demonstrate ultrahigh efficiency OLEDs via a device strategy based on forward light scattering.
