Paper Abstract

A full-color, top-emission active-matrix organic light-emitting diode display build on a flexible substrate (flexible OLED) has been successfully driven by organic-TFTs made by a scalable manufacturing process (lift-off and shadow mask free process). The OTFTs were fabricated with low cost metal (copper and aluminum) electrodes. The backplane architecture was developed at low temperatures (<150°C) with solution-processed organic dielectrics. The fabricated TFTs are reliable against bending stress with 2-mm radius. With this ultra high flexibility of the OTFT, the display shows no significant degradation for an operating period >25 hours with more than 10,000 times bending.
