Abstract
An organic light emitting diode (OLED) assembly (100), comprising: a diode superstructure (110) comprising a cathode (140), an anode (120) having a refractive index of na, and an organic light emitting semiconductor material (160) interposed between the cathode (140) and the anode (120); and a light diffracting substructure (150) providing a scattering cross section of light from the diode superstructure (110). The light diffracting substructure (150) comprises: a transparent substrate (156), a plurality of nanoparticles (154) in contact with the substrate (156) and having a refractive index of ns, and a planarization layer (152) over the nanoparticles (154) and having a refractive index of np. Further, np is within 25% of na and ns>np In addition, ns> about 1.9.
