ACCELERATE DEVELOPMENT OF NEW BUSINESSES
LEDs have become the focus of attention as next-generation lighting
sources. As demand for higher light output and longer life for individual
LED modules grows, measures to combat the heat these modules gener-
ate will be critical. Glass materials are resistant to deterioration from heat,
and Konica Minolta has advantages in glass and plastic mold technologies.
We will leverage these capabilities to offer seals, lenses and other compo-
nents for LED modules.
The scope of use for inkjet printers extends far beyond printing to include
potential applications in manufacturing and an extremely diverse range of
other applied fields. Konica Minolta has proprietary technology in piezo-
electric DOD (drop on demand) techniques, and also sells products such
as high-performance printer heads compatible with a variety of media
(paper, film, fabric, metal and other basic materials), multi-functional ink,
and textile printers. With the adoption of inkjet technology gaining ground
most notably in the commercial printing field, Konica Minolta will extend its
business scope to include the field of industrial printing.
Leveraging the superior qualities of thin, lightweight, flexible film light
sources, Konica Minolta will establish a base in the environment and
energy field as a new business.
