OLED is a new display technology. Using light-emitting organic materials, beautiful and efficient displays can be created. OLEDs are very thin, and in fact can be put on flexible materials (plastic or metal foil). So it's possible to make bendable, flexible displays. Because these displays will not be covered with glass, they'll also be more durable - and virtually shatter-proof.
Samsung showcased its new display technology, known as Youm, at the Consumer Electronics Show in January. The company said it was originally looking to bring its flexible display technology to consumer devices by the end of 2013 or early 2014. Of note, rival handset and display-maker LG has announced plans to be the first company to incorporate flexible displays into smartphones later this year.
