The Holst centre has released a nice video about flexible OLED lighting. They show some nice concepts, and an interesting idea that you can 'cut your own OLED shape' - buy a square-panel OLED, and then cut it... as it will still work. They show this in the video.
Follow this link to the video.
Just last month, the Holst centre has shown an ITO-free, Printed Flexible OLED lighting, paving the way to low-cost large-size OLEDs.
