South Korean scientists claimed to have developed an efficient "true blue" material that can accelerate the development of organic light-emitting diode (OLED) displays.
The breakthrough by Jin Sung-ho's team at Pusan
is significant because it
can accelerate the development of color OLEDs that
have the potential to replace conventional liquid
crystal displays (LCDs).
The discovery would allow the creation of "energy
efficient" OLED displays with increased lifetime and
better picture quality .
OLEDs must be made to mix green, red and blue
lights, in order to offer maximum color and clarity.
Scientists have been able to make efficient green
and red organic light-emitting materials in the past
although they have run into complications with blue.
Past blue materials faded more quickly than the
other two colors, and those made tended towards a
greener shade rather than being true blue.
The latest developmen has been funded by the S.
korean Ministry of Education, Science and Technology
and published in the latest online issue of Advanced
