CROWN New Materials’ Tapes: Driving Innovation in Foldable Screen Development

Foldable devices are evolving toward being thinner, lighter, and more durable. However, foldable screens face a series of challenges during shipping and everyday use. For example, repeated folding can cause creases that affect display quality. In addition, hinges and folding areas are prone to gaps, which can allow moisture and dust to enter, potentially reducing the device’s lifespan over time.

To effectively address these challenges, CROWN New Materials has introduced a range of bonding solutions specifically designed for foldable devices, including optical lamination for foldable screens and other screen bonding applications. These solutions significantly enhance the durability of foldable screens, ensuring high-quality performance throughout the device’s lifecycle and perfectly meeting customers’ demands for high-performance foldable devices.

Optical Lamination for Foldable Screens — OCA:

CROWN New Materials’ OCA for foldable screens is designed for optical lamination of flexible substrates, AMOLED panels, touch films, polarizers, and thin cover films in foldable devices. This tape features minimal changes in elastic modulus, maintaining stable hardness and flexibility during bending, effectively reducing material fatigue caused by repeated folding. Its excellent creep recovery rate and low high-temperature creep variation enhance the screen’s heat tolerance, ensuring stable folding performance across a range of temperatures and delivering an outstanding user experience over the device’s lifespan.

Bonding Applications for Foldable Screens — Foldable PU Foam Tape:

CROWN New Materials’ foldable PU foam tape uses a modified low-modulus acrylic adhesive, offering superior CPI bonding strength and bending durability. It provides excellent tensile and peel resistance during repeated folding and unfolding of the screen. The ultra-thin foam design effectively distributes stress and withstands various mechanical impacts. The adhesive layer’s compression rebound and tensile strength are matched to the foam, preventing delamination. Additionally, an optional mesh film design further improves venting, enhancing overall tape performance.

Beyond these innovative bonding solutions for foldable displays, CROWN New Materials’ EMI series, thermosetting adhesive films, consumer electronics EPT, easy-peel tapes, and protective films also demonstrate broad application potential in foldable devices. With strong technical support and a comprehensive service system, CROWN New Materials continuously advances the successful application of its products in the consumer electronics industry, driving innovation and industry upgrades.
