A rapid, scalable, and noninvasive lithography is reported as a pixel patterning method for large-area flexible organic light-emitting diodes (OLEDs). Effective pixel separation is achieved by highly aligned printed organic fibers with diameters from several hundreds of nanometers to approximately 1 μm. This method, developed by T.-W. Lee and co-workers on page 967, suggests a possible replacement of photolithography for the large-area patterning of passive matrix OLEDs, banks in active matrix OLEDs, and grid patterns in white OLEDs.
