You See, We Display

The Display Business Unit develops and provides various optical films for displays based on fine patterning processing/replication technology and polymer material design/formulation technology. We will satisfy the development demands of the ever-changing market through constant research and development and total solutions.

01 Optical Film

"Optical Film" refers to various thin film materials with optical properties used in applications such as smartphone, tablet, laptop, and automotive displays. It is primarily applied in sheet form to display devices. Our Display Business Unit utilizes precision patterning/replication and polymer material design/formulation technologies to develop and provide a wide range of optical films for displays. We strive to satisfy the evolving demands of the market through continuous research and development and total solution offerings.
