Display Lamination Tapes

Optically Clear Adhesive Tapes

Displays are integrated into more devices than ever before. As new markets grow, new materials and application demands create new challenges for optically clear adhesives. Our assortment reflects this diversity by offering materials with special features to support this dynamic and diverse market. We also know that constant development is needed, and we are working with top industry suppliers to shape and support the next generation of displays.

tesa^® OCA

Our comprehensive assortment is designed to provide a solution for different kinds of applications. All our materials are produced in a clean room and easy for handling, while also being environmentally stable and compatible with other display layers.

Typical applications of our display lamination tapes

When laminating a display, there are certain basic requirements for an OCA: optical clarity, high transmission, low haze, high bonding strength, and easy lamination. In addition, each special application has its own specific requirements.

Flexible layers

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.

Touch panel to display panel

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.

Cover lens to touch panel

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.

Product development pipeline

In addition to our active assortment, we are developing new materials to support handheld devices with foldable and curved-edge displays, as well as backside cushioning tape. Furthermore, we are developing new OCA tapes for automotive, and other moisture-control tapes for OLED and organic solar cell laminations.
