S. Korean laboratory develops key technology to make next-generation display
DAEJEON, April 15 (Yonhap) -- A South Korean state-run laboratory said Wednesday that it has developed core technology that will speed up production of next generation display panels.
The Daejeon-based Electronics and Telecommunications Research Institute (ETRI)
said it has created a transparent, oxide transistor and using this, developed a
very stable light modulator that enhanced the aperture ratio of a active matrix
organic light-emitting diodes (AM OLED) display.
The lack of a stable light modulator had been a major drawback in AM OLED
development, while a higher aperture ratio cuts back on energy use and increases
operational life of displays.
AM OLEDs are viewed as the future of display panels because they do not need
so-called backlights, and compared to widely used thin film transistor liquid
crystal displays (TFT-LCD), provide superior picture quality and contrast under
all conditions. The displays also have 1,000-fold reaction time to moving
pictures compared to TFT-LCDs, can be operated in high and low temperatures, and
be viewed from any angle.
ETRI said it developed the new oxide transistor by using atomic layer deposition
process that greatly enhances operational stability and showed excellent
electronic and optical qualities.
If the technology is further developed it could allow companies to turn regular
building glass into TVs, attach navigational maps on the windshield of cars, and
open wide range of use for ordinary show windows at stores and various mobile
digital equipment.
The institute said it has requested 51 domestic and international patents and
currently engaged in talks to transfer the technology to a private company.
"The technology can allow the country to dominate the transparent display
market," said a ETRI spokesman, adding that since the basic technology was
created here there is no need for local companies to pay royalties.
He forecast that the global market will materialize around 2012 with demand to
expand to US$20 billion by 2015.
The breakthrough has been published in such leading technology publications as
Advanced Materials, and NPG Asia Materials.
