It is not science fiction to imagine that flexibility will be pushed to its limits. OLED lighting could be wrapped around a pillar. Displays can already be folded like a newspaper without loss of image quality. OLED displays have their competitors too. One of them is quantum dots, inorganic materials that are excellent emitters of light.
Quantum dots provide even better colour purity than OLEDs, but the technology is still not ready for commercial use. They are being used in some LCD displays for some time.
