Abstract: An organic light emitting device is provided. The device includes an anode, a cathode, and an organic emissive stack disposed between the anode and the cathode. The device may be a “pixel” in a display, capable of emitting a wide variety of colors through the use of independently addressable “sub-pixels,” each subpixel emitting a different spectrum of light. In the most general sense, the device includes a first subpixel and a second subpixel, and at least one of the anode and the cathode has independently addressable first and second regions corresponding to the first and second subpixels. The device includes an emissive stack disposed between the anode and the cathode. The emissive stack includes a first organic emissive layer and a second organic emissive layer. The first organic emissive layer is disposed between the anode and the cathode, and extends throughout the first and second regions. The second organic emissive layer is disposed between the anode and the cathode, and extends throughout the second region but not the first region. The second organic emissive layer is disposed closer to the cathode than the first organic emissive layer. The first organic emissive layer is emissive in the first region, and the second organic emissive layer is emissive in the second region.

Abstract: The present invention relates to efficient organic light emitting devices (OLEDs). More specifically, the present invention relates to white-emitting OLEDs, or WOLEDs. The devices of the present invention employ two emitters in a single emissive region to sufficiently cover the visible spectrum. White emission is achieved from two emitters in a single emissive region through the formation of an aggregate by one of the emissive centers. This allows the construction of simple, bright and efficient WOLEDs that exhibit a high color rendering index.

Abstract: Charge transport enhancement layers and structures are provided that may improve the performance of organic devices, specifically organic light emitting devices. A charge transport enhancement layer may include a layer or an inorganic material, metal oxide, halide, and/or alkali disposed between two organic layers, and separated from the cathode by an intervening organic layer. One or more CTELs may be used, such as in an alternating stack of organic and CTEL layers. Surprisingly, it has been found that the use of one or more CTELs arranged in a stack with intervening organic layers may improve the performance of the device even where the layer is not directly adjacent to the cathode.

Abstract: An organic light emitting device is provided having an emissive layer with an internal interface. The concentration of a second phosphorescent material in a second organic layer is different from the concentration of a first phosphorescent material in a first organic layer, creating the interface. The materials in the first and second organic layers may be the same or different. In addition to this interface within the emissive layer, the device has one or more features designed to mitigate failure mechanisms which may be associated with electrons or excitons passing from the cathode through the emissive layer to damage organic layers on the anode side of the emissive layer. In addition, devices are provided having an interface within the emissive layer as described above, and a lower energy emissive material on at least one side of the interface.
