Patterning electroluminescent materials with feature sizes as small as 5 mu m using elastomeric membranes as masks for dry lift-off

High resolution displays require simple, reliable methods to pattern electr oluminescent materials. Here is reported the fabrication of soft, elastomer ic membranes containing holes with diameters ranging from 5 mu m (see Fig.) to 50 mu m. By use of two membranes, the authors demonstrate multicolor ph otoluminescent patterns of organic materials with a solvent-free, non-photo lithographic method.
