ORGANIC LIGHT EMITTING DEVICE BASED LIGHTING FOR LOW COST, FLEXIBLE LARGE AREA SIGNAGE |
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.
