R&D History and Organization

Sumitomo Chemical Polymer OLED

In 1989 Sumitomo Chemical Co., Ltd. (Sumitomo Chemical) launched polymer OLED (PLED) research. In 2005 Sumitomo Chemical and Cambridge Display Technology Ltd. (CDT) Opening a new window formed a strategic partnership (JV) 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 opening of a new research institute, the Electronic Devices Development Center, in Ehime (2008).

In 2011 Tsukuba Research Laboratory was reorganized into Advanced Materials Research Laboratory and Tsukuba Material Development Laboratory, where PLED R&D is currently based.

The manufacturing facility for PLEDs has been completed at Osaka Works (2011).
