Keiwa's Opalus light-diffusion film is said to hold a high share of the global market, with adoption across a broad range of applications including smartphones, tablets, notebook computers, and automotive monitors.
Keiwa's mainstay product is the Opalus light-diffusion film. The company is said to hold a high global market share thanks to technology that evenly diffuses backlight across the screen and suppresses unevenness. Its target markets include compact smartphones, mid-sized tablets, and notebook computers, as well as automotive monitors. The product is valued for delivering high-quality display performance.
Key points in the company's history include its transformation from the textile and processed-paper businesses, in which it was founded in 1948, and its entry into the display field. In 1992, Keiwa invented the Opalus diffusion film for displays and shifted the core of its business to optical films. By adding Ultra Precision to its SLC (Sheeting, Laminating, and Coating) technologies, it established a structure for supplying high-value-added products.
