1. A light emitting assembly, comprising:
- two or more devices joined into a layered structure, wherein each of the two or more devices is configured to be individually illuminated, and wherein each of the two or more devices comprises;
a bottom electrode, wherein the bottom electrode is electrically contiguous;
a layer comprising one or more electroluminescent organic materials in electrical contact with the bottom electrode; and
a top electrode, wherein the top electrode is electrically contiguous and in electrical contact with the layer, wherein at least one of the bottom electrode, a component of the layer, or the top electrode is physically or chemically patterned to form a design configured to be illuminated.

Abstract
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.
