In January 2013, Merck said that the performance gap between soluble and evaporable OLED emitters is closed – at least in the lab. Earlier this month at the OLED World Summit the company revealed the development results of their phosphorescent materials, comparing them to UDC’s materials (as published on UDC’s website). Merck’s red emitter features an efficiency of 19.1cd/A, a lifetime (L90) of 5,900 hours and the CIE is (0.66, 0.34). UDC’s red material features an efficiency of 29 cd/A and a lifetime of 23,000 hours. Merck’s green material features an of 76.4cd/A, a lifetime of 5,200 hours, and the CIE is (0.32, 0.63). UDc’s green features an efficiency of 85 cd/A and lifetime of 18,000 hours, The CIE is similar (0.31, 0.63).
