42LINTEC INTEGRATED REPORT 2019Toward the Development of New Materials that Transcend Traditional Technical FieldsIn recent years, LINTEC has achieved research results that transcend our traditional core technologies in adhesive development and coating. Specifically, we have established development and production technologies for liquid adhesives and base film itself that are used in special applications. This marks a major step forward for the next stage of growth for the LINTEC Group.Reflective LCD that uses light diffusion film (right)GPS navigation system for bicyclesThe development of new products and the creation of new businesses will be driving forces that are indispensable for the sustained growth of the LINTEC Group. This section introduces a few of the R&D initiatives that LINTEC is currently advancing, with a focus on the future.On the Front Lines of Product DevelopmentDiagram of an LED PackageTransparent resinWireLED chipSubstrateDie bonding agentWide Range of Potential Applications for Light Diffusion FilmsLight diffusion films can be used in a wide range of applications, including rear-projection and front-projection large-scale digital displays and a variety of display boards. LINTEC is proposing the use of these films in such applications as adver-tising on glass surfaces in stores and guidance displays in public facilities. As display boards, they have a high level of brightness, and the appearance can be changed in accordance with the viewing angle. We are leveraging these character-istics and advancing development to further expand applications.LEDs are electronic components that emit light when an electric cur-rent flows through them. LINTEC developed a liquid functional adhesive that is used to affix LED chips to substrate. Through funda-mental research conducted over many years, LINTEC developed products that provide the required high-level capabilities, such as light and heat resistance, which prevent aging from light and heat, and adhesive strength that is compatible with long periods of use. These products have been highly evaluated in the market, and their use by LED manufacturers is steadily increasing. Moving forward, we will strive to make further progress in materials development, with a focus on the growing use of LEDs in such applications as lighting and elec-tronic equipment.Light Diffusion FilmsGlassScreen (light diffusion film)ProjectorRear-Projection SystemSpecial Feature 2LED Die Bonding AgentsStrategyThrough the formation of two special layers with different refractive indexes within a film, LINTEC has created light diffusion films that pro-vide efficient, optimal diffusion of incident light in the necessary direction. When used in reflective displays, which display information by reflecting sunlight or room light, these films have the potential to make the displays brighter than before. Reflective displays, which do not use backlighting, make a significant contribution to reducing power con-sumption in electronic devices, and as a result their use is expected to grow in such applications as smart watches.
