Toyoda Gosei, Showa Denko form GaN LED JV

May 1, 2012 — Showa Denko K.K. (SDK) will transfer 70% of its gallium-nitride (GaN)-based blue light emitting diode (LED) chip business into a new company, tentatively named TS Opto Co. Ltd, with Toyoda Gosei Co. Ltd.

The joint venture (JV) will be established by December 2012, in Ichihara City, Chiba Prefecture, Japan. The JV partners already collaborate. The new company will expand overall supply capacity, and achieve synergies in R&D for improved brightness and production efficiency with GaN LEDs. Toyoda Gosei will own 70%; SDK 30% of TS Opto.

SDK produces and sells LEDs based on aluminum-gallium-indium-phosphide (AlGaInP), gallium-arsenide (GaAs), gallium-phosphide (GaP), and GaN. Learn more at
