The present invention is a method of selecting composite sheet materials for use in ultra-fast laser patterning of layers of organic thin film material such as OLEDs. The material is selected to accomplish patterning of upper layers without damaging underlying layers by using an ultra-fast laser programmed...http://www.google.de/patents/US7773216?utm_source=gb-gplus-sharePatent US7773216 - Composite sheet material selection method for use in ultra-fast laser patterning
