OLED lighting device with short tolerant structure

摘要

A first device that may include a short tolerant structure, and methods for fabricating embodiments of the first device, are provided. A first device may include a substrate and a plurality of OLED circuit elements disposed on the substrate. Each OLED circuit element may include a fuse that is adapted to open an electrical connection in response to an electrical short in the pixel. Each OLED circuit element may comprise a pixel that may include a first electrode, a second electrode, and an organic electroluminescent (EL) material disposed between the first and the second electrodes. Each of the OLED circuit elements may not be electrically connected in series with any other of the OLED circuit elements.
