Back in October 2011 Samsung Electronics said that it plans to launch products with flexible OLED panels next year, probably starting with mobile phones, then followed by tablets and other portable devices. Today an assistant president at SMD confirms this, and says that flexible OLED panels will be produced in 2012.
Those OLEDs will be plastic based, but probably not really bendable. SMD's AP says that the flexibility will be determined not by the OLED itself but the underlying substrate. Such a "flexible" but non-bendable plastic based OLED will have the advantage of being thin and shatterproof.
