Illuminating the OLED Lighting Roadmap

Breakthrough
In late 2006, a breakthrough was announced Royal Philips Electronics and Novaled. It is a record combination for efficiency and lifetime of high-brightness OLEDs. Philips Lighting, Philips Research and Novaled collaborated on the research effort that produced the breakthrough. The new record for a white OLED’s power efficiency was 32 lm/W with color coordinates of 0.47/0.45 and a CRI of 88 at a brightness of 1,000 cd per meter-squared. That device structure shows a lifetime of more than 20,000 hours, which is promising for future commercialization of the OLED technology for lighting applications.
