Plastic Substrates for Flexible Electronics

Flexible electronics have attracted people’s huge interest, mainly due to their unique features such as lightness, thinness, and design freedom. In addition, they can be manufactured through roll to roll process, which can bring dramatic manufacturing cost down. Flexible displays have been known to be one of the most promising flexible electronics

There are two main components required for achieving flexible displays. They are flexible substrate and flexible TFT. As a material company, KOLON has been concentrating on the development of flexible polymeric substrates.

We have developed colorless polyimides (CPI), which are transparent and thermally stable unlike conventional polyimides. They can be used not only as a bottom substrate for flexible transparent display but also a cover window. The first target application of our CPI film is the cover window, which means the replacement of reinforced glass.

We have been also developing CPI solution (CPI-V) as a substrate for transparent devices. The CPI-V is applicable to oxide-based TFT as well as touch screen panel as a substrate.
