Technology:
Futaba successfully
developed an organic electroluminescence (EL) display that is one seventh as
thin as the existing organic EL displays, and will make a mass production
system ready by the end of this year both in Japan and China. The thickness of
the newly developed organic EL display is merely 0.29 mm, while Futaba’s
existing similar product is about 2.0 mm thick. At the same time, the new
product is about one tenth in weight as the existing product. A 2.7-inch
display weighs only 1.3 g. The new product will easily be applied to
sub-displays of smartphones and wristwatches that work together with
smartphone.
It was necessary to
make an organic EL display hollow architecture to prevent moisture from
sticking to organic EL elements. However, Futaba developed new core materials
and eliminated the hollow portion, and successfully made the organic EL display
thinner and lighter drastically. The new product will be 40-50% higher in price
than Futaba’s existing product. However, the company will adopt the passive
matrix for the new product instead of the active matrix for the production
system. The former is suitable to produce smaller than 4.0-inch displays, while
the latter is suitable to build TV panels. Accordingly, the cost per the same
area will be lower. Futaba acquired TDK’s subsidiary involved in the organic EL
business in April, and it is accelerating research and development to restore
profitability.
