Toyobo Develops Polyester-based Super Retarder Film
 

Tokyo, Feb 15, 2013 (JCN) - Through joint research with Professor Yasuhiro Koike of Keio University, Toyobo has developed COSMOSHINE, a polyester-based super retarder film (SRF) that uses the features of LED light sources to eliminate interference fringes (rainbow mura).

Toyobo previously developed and marketed COSMOSHINE, an optical film used as the base film in LCDs.

The aim of the new research was to develop films with new functions, with the concept of "combining the features of LED light sources and SRF technology to create LCDs that have not existed previously".

COSMOSHINE (SRF type) is a new kind of film made possible by a contrarian concept that overthrows existing common knowledge that held that materials, other than polarizer materials used thus far in LCDs, must be isotropic.

Toyobo hopes to develop the market for COSMOSHINE not only as a base film for LCD backlight materials but also as a material for LCD units.
