Data from spin coated devices using a common cathode and interlayer material demonstrate lifetimes for recently developed solution-processable green and red PLED materials of 78,000 hours and 67,000 hours, respectively, from an initial luminance of 1000 candelas per square meter, or cd/m2. This is equivalent to approximately 445,000 hours and 420,000 hours from an operating brightness of 400 cd/m2 for these materials.

These latest lifetimes represent a 60% and 280% increase in performance for green and red materials over results that were announced in May and March of this year, respectively.
