Plasmacluster Ion technology inactivates and eliminates
airborne viruses, mold and other impurities by releasing a
large volume of positive and negative ions into the air. This
technology was first incorporated in a Sharp product in
2000. Conventional air purifiers are passive devices that
simply filter out impurities. But Plasmacluster Ion technol-
ogy is a unique and completely different technology that
instead directly attacks airborne impurities.
Many research institutes in and out of Japan have
demonstrated that Plasmacluster Ion technology can sig-
nificantly reduce the activity of viruses, mold, mite feces
and bodies, and other airborne allergens that are not vis-
ible to the naked eye. In December 2008, cumulative
sales of Sharp and other companies’ products featuring
Sharp’s Plasmacluster Ion technology surpassed 20 million
units. We will continue to develop this business with the
goal of filling every space with Plasmacluster Ions.

Contributing to Better Health and a Better Environment with
Exclusive Technologies
In the past, home appliances were designed mainly to make household chores easier to do. Today,
consumers have various pressing concerns. In particular, people today are seeking products that
can protect the health of their families and play a part in resolving environmental issues in their
everyday lives. In addition to considering convenience and ease of use when designing new home
appliances, we will also seek to emphasize health and the environment.

LED lights are superior in many ways to incandescent and
fluorescent lamps. Advantages include lower power con-
sumption, a longer service life and the absence of mer-
cury. As a result, these environmentally responsible lights
are viewed as the next generation of lighting products.
LED lights are revolutionary devices in that they use semi-
conductors in the role of a light.
We have been studying LED devices and commercial-
izing products using LEDs for over three decades. In 2008,
we started selling industrial LED lights, combining our
expertise in developing devices with proprietary optical
and heat radiation designs. We are taking the lead in utiliz-
ing this progress. At our 21st Century Manufacturing
Complex in Sakai, Sharp LED lights will be the primary
illumination source. Using this technology will make the
Sakai complex one of the largest facilities in the world
illuminated throughout by LEDs. In June 2009, we
announced a move to introduce this lighting technology
for residential use as well with LED lamps.
Sharp is also advancing with the development of
applied products such as solar-powered LED lights, and
LED security lights. These will form part of our future
expansion of the LED lighting business.
