DuPont materials promise OLED expansion

OLEDs are beginning to penetrate key applications in small displays such as cellphones and MP3 players. With a new technology, DuPont OLEDs can compete in a larger range of products. DuPont has made what it considers a significant technology breakthrough in its OLED technology - a 'significant step toward commercialization of next-generation flat panel displays'.

Thanks to its proprietary advanced materials, DuPont has for the first time combined high performance and long lifetime of small molecule OLED materials with a printing process that is substantially lower cost and more scalable to larger display sizes than the industry incumbent processes, such as CVD.

Through a combination of innovative processing device architecture and new materials, DuPont has demonstrated printing of small molecule OLED materials from solution.
DuPont has achieved lifetimes of the three primary colours each exceeding 10,000 hours of white lifetime (or 40,000 hours for a typical video) at the brightnesses required for a 200 nit display. With this development, DuPont has demonstrated that OLEDs can be manufactured at high yields and low total cost.

"Our model shows that the total cost of OLEDs can be 30% less than LCDs," said Craig Naylor, group vice president - DuPont Electronic & Communication Technologies. "Our proprietary materials are also designed to use less power than LCDs. And OLED displays can be very thin - under 1 mm. With this development, we expect OLEDs will become the next generation flat panel display technology."
