Electric Corporation has recently installed a six-meter organic
light-emitting display (OLED) globe at the National Museum of Emerging
Science and Innovation in Tokyo, Japan. The OLED “Geo-Cosmos” display
will be unveiled at the museum as the world’s first large-scale
spherical OLED screen on June 11.
18 m from the floor, the globe is an aluminum sphere covered with
10,362 OLED panels, each measuring 96 x 96 mm. Mitsubishi Electric used
its scalable OLED technologies to create the globe, which replaces a
globe comprising light emitting diodes (LEDs) to commemorate the
museum’s 10th anniversary. The globe will display scenes of clouds and
other visions of the earth taken from a meteorological satellite.
Projections will feature resolution of more than 10 million pixels,
about 10 times greater than that of the LED display.
addition to Mitsubishi Electric, which created the OLED system, three
other companies helped to make the OLED Geo-Cosmos display: Dentsu Inc.
undertook project planning, Go and Partners, Inc. developed the
image-processing and transmission system, and GK Tech Inc. created the
Geo-Cosmos in construction. Image: Mitsubishi Electric Corp.
OLED components themselves are based on Mitsubishi’s Diamond Vision
technology, which was first introduced in large-scale format last fall,
and first seen in curved form in February 2011. Jointly developed
between Mitsubishi Electric and Tohoku Pioneer Corporation, Diamond
Vision creates light through electro-luminescence. Each pixel consists
of an anode and cathode separated by a thin, organic membrane.
forward, Mitsubishi Electric will continue to expand OLED screen sales
by leveraging its scalable OLED technologies enabling all types of
non-linear display applications.
