Universal Display (UDC) logoUDC describes a new simplified WOLED architecture that represents an important milestone toward the achievement of cost-effective OLEDs for lighting applications. Offering a warm white color with CIE coordinates of (0.45, 0.46) and 30 lumens per Watt (with outcoupling), this WOLED device boasts an extremely long operating lifetime, exceeding 200,000 hours at 1,000 cd/m2, and may be suitable for a variety of entry lighting products.

Dr. D’Andrade will also report on a new white OLED with record-breaking power efficacy of 72 lumens per Watt. Both devices use transport and injection materials provided by Universal Display’s collaboration partner, LG Chem.

This work was funded, in part, by the U.S. Department of Energy (DOE) through its Small Business Innovation Research (SBIR) program. Under the SBIR program and the Solid State Lighting Initiative, the DOE is working to accelerate advances in OLEDs as an energy-efficient, solid-state lighting technology. The DOE views OLEDs as “a pivotal emerging technology that promises to fundamentally alter lighting in the future.” Through the use of Universal Display’s PHOLED technology, WOLEDs have the potential to meet the DOE’s future performance targets, including a power efficiency of 150 lumens per Watt, in an exciting new thin form factor.
