In 2013, Guangzhou New Vision Optoelectronics (New Vision) developed a flexible 4.8" AMOLED display using an Ln-IZO backplane and a polyimide substrate. New Vision now unveiled another flexible AMOLED prototype, this one using a PEN substrate. The company says that they expect flexible OLEDs to be commercialized in the near future.

The new full-color display is 5-inch in size with a thickness of only 0.1 mm and a weigh of less than 5 grams. The radius of curvature is up to 1 cm. New Vision says that PEN is preferable to Polyimide because it's cheaper, it doesn't require the complex preperation process required by PI and it enables transparent panels. The PEN substrate limits the production temperature to 180 C which created a major challenge for New Vision (to deposit the Oxide-TFT backplane at that temperature).

New Vision also said this new panel uses a new type of thin-film encapsulation technology, but they did not reveal any technical details on that.
