摘要： A device is provided. The device includes a substrate, a first electrode disposed over the substrate, a small molecule organic emissive layer disposed over the first electrode, and a second electrode disposed over the organic emissive layer. The substrate has a first index of refraction, and the organic emissive layer has a second index of refraction. The first index of refraction is higher than the second index of refraction. The device may have an external electroluminescent efficiency of at least about 56%. Bulky substituents or dopants may be used to decrease the index of refraction and/or the density of the organic emissive layer.

摘要： The present invention relates to an organic light emitting device (OLED) for producing electroluminescence having, in order, for example, an anode, a hole transporting layer (HTL), a blocking layer, an electron transporting layer (ETL), and a cathode. In the devices of the present invention, the hole transporting layer comprises a polymeric material, which material may be emissive or may be doped with an emissive dopant. The blocking layer and the electron transporting layer are small-molecule materials. The presence of a blocking layer confines the emission of light to the polymer layer, which may be a HTL or a separate emitting layer (EL). The devices of the present invention are suitable for use in single color, multi-color and full-color, passive or active matrix OLED displays.

摘要： OLED devices are disclosed having increased external electroluminescence quantum efficiencies, i.e., increased “out-coupling” efficiencies. OLED devices that have increased out-coupling efficiencies and that are also protected from environmental elements such as moisture and oxygen are also disclosed. The OLED device of the present invention comprises a substrate; an active region positioned on the substrate, wherein the active region comprises an anode layer, a cathode layer and a light-emitting layer disposed between the anode layer and the cathode layer; and a polymeric layer disposed (a) over the active region, (b) under the active region or (c) both over and under the active region. The polymeric layer has microparticles incorporated therein, and the microparticles are effective to increase the out-coupling efficiency of the OLED. In one embodiment, the OLED device comprises a composite barrier layer and the microparticles are incorporated in a polymeric planarizing sublayer of the composite barrier layer. The composite barrier layer in this embodiment also protects the OLED from damage caused by environmental elements such as moisture and/or oxygen.
