World Record in OLED Power Efficiency!

With rising energy costs and the increasing prominence of mobile devices, power efficiency is becoming more and more significant in today's world. In general, a high current efficiency of OLEDs is dependent on two factors: the emission layer and a good charge carrier balance. Provided the current efficiency remains unchanged, these factors, in combination with a very low driving voltage, produce high power efficiency. Using its proprietary PIN technology, Novaled is able to combine very low operating voltages, while simultaneously maintaining a good charge carrier balance and high current efficiency. This has resulted in the highest reported power efficiency for OLEDs. Using an optimized organic layer stack with doped transport layers, Novaled can demonstrate e.g. 120 lm/W at 1,000 cd/m2 (with out-coupling enhancement) in a green bottom emission PIN OLED - world record!
