Cambridge Display Technology (CDT) and Sumation are pleased to announce new growth in lifetime metrics for red, green, blue, and white PLED materials.

Data results from spin coated devices using a common cathode and solution processable materials developed in 2006 demonstrate that lifetimes(a) of 24,000, 35,000, 10,000, and 5,200 hours for red, green, blue, and white, respectively, have been achieved from an initial luminance of 1000 cd/m². This is equivalent(b) to over 150,000, 198,000, 62,000, and 27,000 hours from an operating brightness of 400cd/sq.m for these materials.
