Dr. Sangmin Song Group Manager of CPI Research Group KOLON Industries, Inc. Abstract:
Development of Colorless Polyimides (CPI®) and its Commercial Production for Flexible Electronics
We can say flexible displays started from the plastic based displays like Galaxy Round and G flex commercialized in 2013, which were unbreakable, durable and bendable but the final devices were still rigid. And then they were evolved into a foldable display, the real flexible displays in some way. And commercialization of foldable mobile are getting started finally using plastic OLED and foldable cover window comes from transparent polyimide film. I’ll cover the development of colorless polyimide and its advantages over the conventional materials. Then I’ll show you what Kolon Industries has been doing for flexible displays with Colorless Polyimides and the status of mass production of CPI® film. Also I’ll talk about some issues of the application of CPI® film to foldable mobiles.
