Researchers at National Nanotechnology Center, NANOTEC investigated the effect of conjugated length of two series of novel emitting material on organic light emitting diodes (OLED) using density functional theory (DFT) and time dependence density functional theory (TDDFT) using computer-aided design approach.
"Research and development in the field of OLEDs is proceeding rapidly and applications are being considered for use on various consumer items" said Dr. Supawadee Namuangrak a researcher at NANOTEC. "Our report indicates that the structural and optical properties of DFT and TDDFT can be tuned by varying the number of thiophene units. These findings can be useful for future studies involving conjugated OLEDs".
According to Displaysearch, the OLED revenues forecast is expected to reach USD 5.5 billion by 2015 up from USD 0.6 billion in 2008. The mechanism that is driving this growth is the primary display in mobile phones and portable media players. Many European and US companies are taking advantage of the Asian economic growth and consumers' desire for OLED technology to consider moving their OLED manufacturing and R&D centers to Asia.
Collaborators on this investigation included researchers from Ubon Ratchathani University. The researchers reported their investigation in a paper published by World Scientific Journal of Theoretical and Computational Chemistry.
