    • 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.
    • 提供有机发光装置。 该装置包括阳极,阴极和设置在阳极和阴极之间的有机发射叠层。 该装置可以是显示器中的“像素”,能够通过使用可独立寻址的“子像素”发射各种颜色,每个子像素发射不同光谱。 在最通常的意义上,该装置包括第一子像素和第二子像素,并且阳极和阴极中的至少一个具有对应于第一和第二子像素的独立可寻址的第一和第二区域。 该装置包括设置在阳极和阴极之间的发射叠层。 发射堆叠包括第一有机发射层和第二有机发射层。 第一有机发射层设置在阳极和阴极之间,并延伸遍及第一和第二区域。 第二有机发射层设置在阳极和阴极之间,并且延伸遍及第二区域而不是第一区域。 第二有机发光层设置成比第一有机发光层更靠近阴极。 第一有机发射层在第一区域中发射,并且第二有机发射层在第二区域中发光。
