    摘要： The present techniques provide light emitting assemblies that include two or more light emitting devices joined into a single multilayered structure. Each device is electrically contiguous, and includes an electroluminescent polymer layer between two electrodes. In each device, the electroluminescent polymer layer and/or at least one of the two electrodes is patterned to form an illuminated design. Each device may be separately energized to illustrate a different pattern or design. In some embodiments, a layer having a contiguous light emitting layer may be attached to the back of the multilayer structure.

    摘要： The present techniques provide methods and systems for forming devices that may be formed from light emitting regions of electroluminescent organic materials. The small size of the light emitting regions allows the formation of blended colors, which may be formed into illuminated designs. Multiple devices may be joined together to form multilayer panels, where nearer layers may have different designs than farther layers, or farther layers may have solid illuminated colors useful as backgrounds for nearer layers. Further, the multilayer devices may be used as color tunable light sources.
