Rapid Advances in OLEDs in East Asia

SpecialChem / Jul 5, 2007

In Organic Light Emitting Diode OLED production and its technology, East Asia leads the world by a big margin, though with the older, glass-based technology and usually through license of key intellectual property from Western companies such as Kodak, UDC and DuPont. Over 70 percent of patents taken out in East Asia on printed and potentially printed components now relate to OLEDs. Consequently, when the earliest key OLED patents, mainly in the West, lapse, a considerable amount of the key intellectual property will probably be located in East Asia. Hard work is proceeding to make the region a leader in the next generation - printed flexible OLEDs, again using knowhow licenses from Western companies, in this case UDC and CDT in particular. However, the first printed semiconductor factory in the world was commissioned in March 2007 in Austria, not East Asia and it can handle flexible substrates. It was the Nanoident production line for photodetector arrays that are basically OLEDs in reverse.
