Cambridge Display Technology (www.cdtltd.co.uk) has tripled the lifetime for its blue light emitting polymer (LEP) technology, which it's licensing to companies that want an alternative for LCD flat panel displays. The Cambridge, UK company's displays don't need backlighting like LCDs, thus LEPs are thinner and consume less power. New material formulations and improved deposition processes boost lifetimes to 11,000 hours. That's significant because blue products had shorter lifetimes than the other LEP colors needed to make full-color displays.
