Laminating flexible layers within a foldable or rollable display requires high peel adhesion and very good bending properties. For some special substrates like silver nanowire, an OCA tape with good compatibility is required.

The lamination of these two layers can be found in LCD as well as in OLED displays. While an easy lamination process and high environmental stability is key for both types of display, OLED displays additionally require high resistance to repulsion forces and better relaxation properties, because of their curved design.

When laminating these two layers, it is necessary to use adhesive tapes that are able to cover ink (gap-filling) and are compatible with ITO. For curved designs, the tape should also have very good relaxation properties. For plastic substrates good outgassing resistance is indispensable.

6940x is our versatile flagship series which is a pressure-sensitive OCA tape that offers a well-balanced profile. It is easy to laminate and convert, and is highly compatible with touch sensor films, polarizers, and cover glass. Best results are achieved when used in rigid/flex or flex/flex applications.

6920x is a pressure-sensitive OCA series which is easy to laminate and convert. It is the best for lamanation of films to protect UV-sensitive materials, as it offers UV-blocking for wavelengths below 380 nm. Best results are achieved when used in rigid/flex or flex/flex applications.

6960x is a UV-curable OCA tape type that is designed for cover glass lamination. It offers superb gap-filling properties to ensure complete ink coverage, and has excellent reliability performance after curing. It is suitable for rigid/rigid or rigid/flex applications.

6980x is a UV-curable OCA tape type that is designed for plastic substrates lamination with excellent outgassing resistance. It has high gap-filling property, and best-in-class bubble resistance after curing. Suitable for rigid/rigid or rigid/flex applications.
