Cheil Industries has become the first Korean manufacturer to develop and produce OLED material. The Samsung affiliate announced on April 28 2014 that it will begin mass producing raw material for green phosphorescent OLED. 

Cheil Industries, a Samsung Group company specializing in textiles, will invest up to 1.8 trillion won (US $1.7 billion) for the next three years in high value-added electronic and chemical materials. The company said this on November 7 in a regulatory filing. The areas it will focus on include OLED (organic light-emitting diode), rechargeable battery separators, and polarized film.
