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.
