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.

摘要： The present invention is directed to novel structures for use in connection with OLED devices that simulaneously act as a multiplayer mirror and as a barrier to harmful species in the exterior environment. According to one embodiment of the invention, an OLED structure includes (a) a substrate; (b) an OLED over the substrate that includes (i) a first electrode, (ii) an emission region above the first electrode and (iii) a second electrode above the emission region, wherein the OLED emits light having a range of wavelengths upon being turned on; and (c) a multiplayer mirror over the substrate, the multiplayer mirror including an alternating series of (i) planarizing layers having a first refractive index and (ii) high-density layers having a second refractive index that differs from the first refractive index. The thicknesses of the planarizing layers and of the high-density layers in this embodiment are selected such that the multiplayer mirror is tuned to transmit light at a peak wavelength within the range of wavelengths emitted by the OLED. Moreover, the planarizing layers and the high-density layers cooperate to restrict transmission of water and oxygen.
