    Abstract: Techniques to fabricate and assemble a lighting system including multiple patterned OLED lighting panels to form a high-resolution macro image are provided. An image to be displayed is determined and divided into multiple portions. Patterned static OLED lighting panels that display each portion of the image are fabricated and assembled into a fixture to form a macro-image lighting system. The fixture may removably receive and hold individual panels, such that each panel may be replaced if any malfunction occurs. Each of the patterned OLED panels may be individually driven through an electrical connection within the fixture so as to be operated at substantially the same brightness and/or same chromaticity.

    Abstract: Systems and methods for the design and fabrication of OLEDs, including high-performance large-area OLEDs, are provided. Variously described fabrication processes may be used to deposit and pattern bus lines with a smooth profile and a gradual sidewall transition. Such smooth profiles may, for example, reduce the probability of electrical shorting at the bus lines. Accordingly, in certain circumstances, an insulating layer may no longer be considered essential, and may be optionally avoided altogether. In cases where an insulating layer is not used, further enhancements in the emissive area and shelf life of the device may be achieved as well. According to aspects of the invention, bus lines such as those described herein may be deposited, and patterned, using vapor deposition such as vacuum thermal evaporation (VTE) through a shadow mask, and may avoid multiple photolithography steps. Other vapor deposition systems and methods may include, among others, sputter deposition, e-beam evaporation and chemical vapor deposition (CVD). A final profile of the bus line may substantially correspond to the profile as deposited.
