Idemitsu and Sony today announced the achievement of 28.5% internal quantum efficiency (IQE) in deep blue fluorescent OLED devices, the world’s highest level of luminous efficiency for this technology. This ground-breaking development is a result of Idemitsu´s advanced OLED material technologies and Sony’s OLED device expertise. The use of Sony’s proprietary “Super Top Emission” OLED device technology has enabled blue color deepness exceeding NTSC standards to be achieved.
With this technology significantly reducing the driving current of blue OLEDs, the most energy-intensive of the three primary RGB colors, it is expected to significantly reduce the power consumption of OLED panels, contributing to the future development of large-size OLED TVs. These results will be presented at “SID2008” to be held from May 18th, 2008 at Los Angeles, CA, U.S.A.
