Cambridge Display Technology (CDT) announces the achievement of another important milestone with the development of blue polymer OLED emitting devices with 100,000 hours lifetime* from an initial luminance of 100 cd/m2.

This latest announcement is one of a series which CDT has made to enable the industry to chart its progress on this key parameter. Figures of 30,000, 70,000 and 80,000 hours (all from 100 cd/m2) were published in May, October and December 2004.

Lifetime is one of the most important parameters which have governed the rate at which PLED technology is adopted commercially, and there is much industry interest in such figures. For this reason CDT has, for the first time, made available a wider range of data around its latest achievement, and included lifetime data for higher initial luminance levels.

Lifetimes for devices made using the new blue materials at 200 cd/m2, 300 cd/m2 and 400 cd/m2 are greater than 25,000 hours, 10,000 hours and 6,000 hours respectively.
