Philips and German firm Novaled have announced white OLEDs operating at a brightness of 1000cd/m² with a record-breaking efficiency of 25lm/W.
work between Philips’ Lighting and Research divisions, and Dresden-based Novaled, combined Philips’ materials selection, optical outcoupling technology, and layer schemes for building up OLED devices, with proprietary doping technology from Novaled.
This is an encouraging result that clearly demonstrates the potential of OLED technology for lighting applications, said Klaas Vegter, chief technology officer of the Lamps business group at Philips Lighting.
The results of the research will be used in future developments, ongoing projects, and the recently started European project OLLA (Organic LEDs for Lighting Applications), in which both companies are involved.
