Flexible displays have been known to be one of the most promising flexible electronics. As a material company, Kolon has been concentrating on R&D of the flexible polymeric substrate. Kolon developed "Colorless Polyimide (CPI)", which has no color and high thermal stability unlike conventional polyimides. They can be used as not only a bottom substrate for flexible transparent display but also a cover window for foldable mobile to replace the glass. Besides the flexible display CPI also can be used for various applications such as automotive,TSP,PCB and semiconductors.
