INTRODUCTIONThe world&＃39;s display market is making much effort to improve the variability of sizes and ability to mass produce displays. Light guide plates of the past required a complex and difficult production process and the limited production of sizes was a stumbling block. Shadai researched ways to improve these problems experienced in the light guide plate and related industries and developed for the first time in the world, optical science sheets that can perform as a light guide plate with only their adhesion on general acrylic. By providing optical science sheets made with patented technology and distinct services, we are working hard to grow into a world class company leading the industry.
