Peter Visser of Philips Lighting, OLLA project manager, says “the high efficiency combined with the extrapolated lifetime values prove that OLED is a serious technology for lighting applications, allowing innovative designs and energy savings”. OLLA’s goal was to match the performance of an energy-saving light bulb with an efficacy of 50 lumens per Watt and a lifetime of over 10,000 hours.
The OLLA project brought together 24 partners from 8 European countries, including Osram, Novaled, Siemens and Philips. The consortium have made key breakthroughs in many areas, including materials, deposition and light out-coupling. Both small-molecule and polymer OLED systems were studied. The final prototype tile is a small-molecule source based on Novaled’s PIN OLED technology.
On the basis of OLLA’s success, there are now several European projects looking into OLEDs. One of these is OLED100.eu, which is a 3-year follow-on project from OLLA.
