CDT announced a red dendrimer OLED device with a 250,000-hour lifetime from an initial luminance of 100cd/m2, compared to the 150,000 hour-lifetime device announced this May and 15,000 hour lifetime in 2004. The company also said it will ally with Sumitomo Chemical for PLED material supply.

Lifetimes for devices using dendrimer technology using the new red materials at 400cd/m², 800cd/m2 and 1000cd/m² are estimated at 15,600 hours, 3,900 hours and 2,500 hours respectively.
