Cambridge Display Technology (http://www.cdtltd.co.uk/) has presented new materials for red and blue OLEDs (Organic Light Emitting Diodes), said to have impressively extended lifetimes. This development has brought large-size full-color displays that make use of the new technology one step closer.
The UK company claims to have produced in cooperation with the Japanese chemical (http://www.sumitomo-chem.co.jp/english/) concern Sumitomo Chemical phosphorescent red OLEDs with an efficiency of over 7cd/A whose initial luminance of 100cd/m2 is said to take some half a million hours to fall to half its initial value (with a drop in the initial value by half being the definition of a lifetime). According to CDT's statements "this is a record for lifetime of solution-processable" OLEDs.
