HYOSUNG Optical Film

1st Mass Production of TAC Film in Korea

In 2009, we built a TAC film plant for LCDs in Yongyeon, Ulsan, and proudly became the first Korean company to start large-scale production. With the completion of the second plant in Oksan, Cheoungju, in 2013, we have increased the annual capacity to 110 million square meters.

World's No.1 Plain TAC mass-production technology and expansion films for next-generation displays

Driven by a commitment to quality that satisfies and builds trust with customers, we are expanding our presence in the global display market. Furthermore, we are also expanding sales in the next-generation display markets such as coating, OLED and automotive applications where high-quality standards are paramount.

Hyosung Optical Film,
the first eco-friendly, high-quality film developed in Korea

With technological advancements in the electronic materials industry, we have designed a new film base on TAC film technology. This film complies with hazardous substance regulations and is eco-friendly made from bio-based materials. Also it is highly durable without TAC acid decomposition and boasts an exceptional level of flatness and surface uniformity.

  • Eco-friendly

    Acquired Eco-friendly certification for
    using a bio-material base

    Meet hazardous material regulations

  • Durability

    No Crystal Mura

  • Flatness

    Excellent coating property

Applications

  • Used in TVs, monitors, laptops, tablets, smartphones

    In principle, TAC Film with high mechanical strength has high optical isotropy as well, allowing polarizers in a certain direction to pass through the TAC Film evenly.

  • AUTO/PID, etc.

    Automotive displays (AUTO) and public information displays (PID) require high-definition quality, fast response times, durability and brightness to withstand harsh external environments. They demand more stringent production and quality management systems and durability than consumer digital devices. * PID: Display panels used to provide media services such as information, advertisements and entertainment in public places and commercial spaces
