Prism film condenses light from a light source, such as LCD BLU, by forming fine prism structures on a polyester film. EverRay® LC is the second prism film to be successfully produced and localized in Korea in 2005, and EverRay® DCS is the first prism film in the world to be produced with outstanding elasticity in 2006. EverRay® BK and LF are composite prism films that provide the features of both diffuser and prism films. With its high brightness and excellent reliability, its market share is growing among domestic and international companies.
Features and Uses
KOLON Industries, Inc.’s prism films provide high brightness using high-refractive materials, and excellent scratch resistance and workability using elastic materials. It has a fine appearance, moist-free, wet out free, and hot-band free, and offers such properties as chemical resistance, scratch resistance, high-temperature/humidity reliability, and high-quality wrinkles

KOLON Industries, Inc. is competing with leading international companies, such as U.S. Dupont, Japan’s Hitachi and Asahi, and now has over 60% market share in the dry film photoresist industry. The company was also the first company to develop dry films and localize them in the market where foreign products were dominant.
Its technology became further recognized through the development of ultra-high resolution films, which require the most advanced technology in the industry. The dry film photoresist market is growing with the expansion of the electronics market, including semiconductors and LCDs, and KOLON Industries, Inc.’s Accuimage® is a photosensitive film with a resist thickness ranging from 7 to 75um and is used for multiple purposes, such as PCB, L/F, and packaging.
The product has met customers’ needs with excellent properties and is increasing market share with outstanding quality and competitive prices compared with existing foreign products.
