IDTechEx released a new flexible OLED display market report, in which they say that the next evolution of OLED displays is plastic and flexible displays. They see fast growth in such displays, with sales reaching $16 billion by 2017. The first flagship flexible display will ship in 2017.
Not all OLEDs will be plastic-based, and this will especially be true for TV applications. In fact, IDTechEx sees OLED TVs also growing very quickly - with a projected 42% CAGR in the next ten years (this will be the second fastest growing OLED application after automotives).
