OLEDs are not only thin and lightweight with excellent energy saving characteristics but also have outstanding high-definition color reproducibility. Although market expansion was forecasted, OLED use was limited by inherent traits including deterioration from contact with moisture and oxygen. In addition, sealing technology was a prime issue in development of more flexible and larger displays. Mitsui Chemicals’ OLED sealing material “StructbondTM XMF-T”, with its high barrier properties, moisture resistance, transparency, and process manageability, resolved these issues.
“StructbondTM XMF-T” allows innovative advances in sealing methods for displays thereby allowing greater flexibility and strength. “StructbondTM XMF-T” technology contributes to LG Electronics G Flex’s high market reputation for its highly usable curved surface design and durable high-definition display.
With “StructbondTM XMF-T”, the design flexibility of OLEDs is greatly enhanced allowing wider and increased applications including wearable electronics and lighting. Mitsui Chemicals, through this and its many other products, will continue to contribute to a better future for people around the world.
