Advancing Display Technology Together — Innovative Applications of CROWN New Materials’ Full-Lamination OCA in OLEDs

With continuous breakthroughs in OLED technology, display technology is rapidly evolving, opening new application scenarios across smartphones, tablets, wearables, and other markets. Market research forecasts that the global OLED display market will continue to grow over the coming years, reaching over $50 billion by 2027 (Source: Sihan Industrial Research Institute). This trend clearly presents significant market opportunities for upstream material suppliers.

As a critical component of OLED displays, rigid OLED has secured a prominent position in the consumer electronics industry thanks to its excellent display performance and durability. To provide better physical protection and structural strength, the addition of a glass cover has become standard practice. However, to maintain optimal display quality, the adhesive layer between the glass cover and the OLED must achieve extremely high transparency and low haze, ensuring that brightness, color accuracy, and contrast remain unaffected. A key technical challenge in this process is residual air—particularly during full lamination, where tiny bubbles or trapped air can cause the Mura effect (uneven brightness), significantly impacting the final display quality.

To address this, CROWN New Materials’ full-lamination OCA, with its exceptional optical performance and adaptability, has become a vital part of high-quality display solutions. Using a UV-curing process, the OCA exhibits high ink step-absorption before curing, allowing it to flexibly accommodate surface irregularities of different materials and ensure uniform lamination. After degassing, the assembly enters the UV-curing stage. This process not only enhances bonding strength but also ensures long-term stability of the adhesive layer, effectively preventing bubble formation or yellowing over extended use. As a result, consumer electronics displays maintain stable performance even in complex environments, significantly improving device durability and delivering an extraordinary visual experience to users.

To meet the technical requirements of various applications in the consumer electronics industry, CROWN New Materials’ full-lamination OCA is available in both G-type and N-type formulations. The G-type OCA, with its exceptional tensile and tear strength, can be easily peeled off without residue during rework, making it particularly suitable for the manufacturing and servicing of electronic devices. This not only improves production efficiency but also reduces rework costs. Additionally, long-term aging tests confirm that G-type OCA maintains bubble-free and non-yellowing performance over extended use, making it widely applied in smartphones, tablets, and other devices.

On the other hand, the N-type OCA features a low elastic modulus that helps distribute pressure more evenly, effectively eliminating the Mura effect. It is especially suitable for high-precision, demanding display applications, delivering outstanding optical performance and display stability.

With over twenty years of industry expertise and technological experience, CROWN New Materials not only provides customized solutions and high-quality products but also assembles dedicated project teams to ensure smooth project delivery. Currently, CROWN’s full-lamination OCA has been successfully implemented by multiple consumer electronics clients, earning widespread recognition and praise. Looking ahead, CROWN New Materials will continue to innovate and evolve, offering more advanced products and efficient services to support the consumer electronics industry in achieving higher quality, smarter, and more sustainable development.
