With this production launch, the company will expand its product offerings beyond the high-performance adhesive materials it already supplies for mobile OLED displays to protect panels from external impacts, adding OCA, which bonds the individual functional layers.


OCA is a key material that seamlessly bonds the functional layers making up OLED panels, such as display panels and cover windows, and improves optical performance by reducing light reflection and loss between layers. It must be designed to ensure high adhesion, flexibility, and resilience.


The market for OCA used in high-end mobile OLED displays has been dominated by a small number of global companies. INNOX Advanced Materials has succeeded in localizing production through its proprietary expertise in adhesive, coating, and film design.


Starting with initial OCA supplies for global high-end smartphone products, the company plans to expand supplies to high-end and premium product lineups, including foldable products, and increase its market share to 30% by 2028.


The company also plans to expand OCA applications to IT devices such as tablets, laptops, extended reality (XR) devices, and wearables, as well as to automotive OLED displays that require high reliability.



An INNOX Advanced Materials representative said, "This OCA supply is significant because we have localized a high-difficulty, core material that was highly dependent on overseas suppliers using our own technology, and substantially expanded the range of products we supply to our customers." The representative added, "We will continue to strengthen our business portfolio across semiconductors, circuit boards, and battery materials, as well as OLEDs, and, drawing on our accumulated expertise in materials design and manufacturing, we will evolve into an advanced materials company focused on solutions that meet the needs of customers and the market."
