Also a real sort of roll up Philips phone using an eink type of display. Perhaps not one of Philips better ideas. Tech sold to someone Asian, then Amazon bought and buried it. It's not used in the Kindle.
Sony also had a roll up eink. Mysteriously not used for rolling up, though the Sony Digital Paper (for PDFs, not ebooks) is reputed to be plastic.
In theory AMOLED (which are really electroluminescent dots, not true LEDs) can be pretty flexible. The unsolved issue is suitably flexible wiring. Millions of nano sized strands in Litz type cables?
