Sumitomo Chemical Polymer OLED
Sumitomo Chemical began developing polymer OLED (PLED) in 1989, and in 2005 it established a strategic partnership (JV) with Cambridge Display Technology Ltd. (CDT) in PLED development.
In recent years, Sumitomo Chemical has accelerated PLED R&D market penetration by acquiring CDT as a subsidiary in 2007, followed by the 2008 opening of a new research institute, the Electronic Devices Development Center, in Ehime.
In 2011, the manufacturing facility for PLEDs was completed at Osaka Works.
In 2014, Sumitomo Chemical started build-to-order manufacturing of PLED Lighting Panels.
