| CDT Sees New Record Display Lifetime Development<BR><BR>Cambridge Display Technology (CDT) announced two major milestones in the development of long lifetime, high efficiency light emitting polymers for full color, video capable displays.<BR><BR>A phosphorescent red device has been produced by CDT and Sumitomo Chemical which has a lifetime of half a million hours from an initial luminance of 100cd/m²; this is a record for lifetime of solution-processable materials of any color. The efficiency is also improved at over 7cd/A. Red efficiency is especially important as this color consumes the largest share of power input in a color device, so improvements in red efficiency have important practical implications.<BR><BR>The second major milestone announced is a lifetime of 150,000 hours for a fluorescent blue device based on a new material developed by CDT, and now part of the Sumation™ portfolio. Just eighteen months ago, CDT announced the achievement of 30,000 hours lifetime for fluorescent blue. The efficiency is also the highest recorded for a blue polyfluorene material at 10cd/A.<BR><BR>The new blue material yields very good color values and efficiency. The OLED industry has come to regard progress on blue materials as a key indicator, since this performance dictates the range of full color applications which can be implemented. The progress announced today gives a strong indication that the technology is moving rapidly to satisfy the requirements for applications including large display screens.<BR> |
