Sumitomo Chemical to Participate in Light+Building 2012
with 60-Color Polymer OLED Lighting
Sumitomo Chemical announced that it will participate for the first time in“Light+Building 2012”, one of the world’s largest trade fair for lighting and building
technology, to be held in Frankfurt, Germany, in April 2012.
The Company will be running a booth at the trade fair, inviting the world-renowned
Japanese lighting designer Motoko Ishii as its art director, where its polymer OLED
lighting will be exhibited, with the theme “The Colors of Japan – The Colors ofHarmony”, in an innovative attempt to replicate—by means of lighting—the elegant andrefined colors of ancient Japan in a modern day setting of a Japanese traditional tearoom
by using the world's most advanced polymer OLED technology.
Displayed at the booth will be large-scale lighting panels of about 10 centimeters square
each, illuminating in sixty different colors, that are produced by coating everything
except for the electrodes with printing technology. Varying shades of color will soothe
visitors comfortably to the world of Japanese traditional colors from the distant past.
Sumitomo Chemical is the first in the world to have produced successfully the large-scale
lighting panels with the printing method in as many as sixty different colors.
In addition to OLED lighting capable of generating natural light that is soft and gentle on
the eyes, polymer OLED lighting offers its unique advantage of producing a countless
number of color shades as well as lessening an environmental impact that can be realized
by the simplified manufacturing process, making it the perfect next-generation lighting
technology.
Leading-edge OLED technology and the Japanese traditional culture of harmonious
colors coming into play— Sumitomo Chemical’s polymer OLED lighting brings together
the time-honored cultural heritage and the world-class technological excellence, in bothof which Japan takes pride.

About Electroluminescence and OLEDs
Electroluminescence is a phenomenon in which light is emitted in response to theapplication of voltage and passage of an electrical current through an organic material.
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.
