Is quantum-dot lifetime adequate for TV applications?

Oct. 8, 2012
Based on input from Nanosys via Ken Werner of Display Central, quantum-dot lifetime is indeed good enough for consumer television.

In mid-September, Ken Werner delivered a presentation on OLED manufacturing and markets at the Crystal Valley Conference and Exhibition (CVCE) in Cheonam, Korea. He writes:

"I mentioned quantum dots and Quantum Dot Enhancement Film (QDEF) as technologies that might slow the market penetration of OLEDs. During the Q&A, Franky So (Prof. of Materials Science and Engineering at the Univ. of Florida) asked a question I couldn’t answer, and it's an obvious one: What is quantum dot lifetime in general, and the lifetime of QDEF in particular? Professor So also speculated that the material system involved might give QDs an inherent lifetime disadvantage compared to OLEDs.

I quickly fired off queries to Nanosys, the company that has led in development of quantum dots (QDs) for display applications, and 3M, which has incorporated Nanonsys QDs into QDEF, a component that can deliver the benefits of QDs while directly replacing the rear diffuser film in LCD backlights.

At the behest of Nanosys Product Manager Jeff Yurek, the technology team at Nanosys quickly put together this response concerning the inherent differences between OLED and QD materials:"
