Product Information
The manufacturing of the optical films for backlights at TSUJIDEN started out by taking notice of the acryl fine spherical particle's diffusibility / transparency / light harvestability which had not been used before. TSUJIDEN used these characteristics of the material to develop a new type of optical diffusion film.

In 1991, it was a small amount, but the film was adopted by LCD manufacturers because of it's characteristic which improved more than over 10% of brightness in comparison with other diffusion films from the past, and now we have a line up of about 30 different types of optical diffusion films that correspond to different specifications and use of backlights (ex: Mobile Phone, Laptop, Desktop computers, LCD TV, Lighting, etc. )
TSUJIDEN has also manufactured several types of reflector films.

Furthermore, as well as developing material, TSUJIDEN has also developed various kinds of secondary processing technologies ( The common Dot printing technology for anti-luminescent lines is a processing technology that TSUJIDEN developed. ) and processing equipment to materialize those technologies.
