Graphene-Based Transparent Electrodes for Flexible OLEDs

The next big thing in consumer electronics could be flexible displays that roll up like a piece of paper. Ever since LG showed off a prototype screen at this year’s Consumer Electronics Show, rollable displays have been a hot research topic. Of course, making one prototype is not quite the same as achieving a flexible display that can stand up to the wear and tear of normal consumer usage. Now, researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a component that could make flexible OLED (organic light-emitting diode) displays actually work—a transparent electrode made from graphene.
