Mar. 7, 2014

--- "The Most Advanced Polymer OLED" ---

Sumitomo Chemical will exhibit its polymer OLED lighting at "Light+Building 2014," one of the world’s largest trade fairs for lighting and building technology, to be held in Frankfurt, Germany, from March 30 to April 4, 2014.

This is the second time for Sumitomo Chemical to exhibit its products at the trade fair, following its first participation in 2012. Sumitomo Chemical will run a booth at the trade fair, inviting the world-renowned Japanese lighting designer Motoko Ishii as art director, where its dual-color emission polymer OLED lighting will be displayed with the theme "The Most Advanced Polymer OLED."

Sumitomo Chemical’s exhibit, named "OLED COSMOS," is formed by polymer OLED lighting panels, expressing the infinite expanse of the universe. Its design indicates unlimited possibilities of polymer OLED ever expanding into the future.

The lighting panels used for "OLED COSMOS" feature bright colors of light, in contrast to delicate Japanese traditional colors produced by the lighting panels Sumitomo Chemical displayed in the previous trade fair. The lighting panels are also extremely thin, which has been difficult to achieve for conventional lighting.

Sumitomo Chemical is the first in the world* to have developed technology to mass-produce dual-color emission OLED lighting panels where a single panel can be printed in two distinct colors based on the Company's highly advanced printing method. Following the exhibit at "Light+Building 2014," Sumitomo Chemical will start marketing its polymer OLED lighting panels in April 2014.

About Electroluminescence and OLEDs

Electroluminescence is a phenomenon in which light is emitted in response to the passage of an electrical current through an organic material as a voltage is applied. Organic Light Emitting Diodes (OLEDs) are a technology that employs this phenomenon. An OLED that employs a polymer as a light emitting material is called a Polymer OLED.
