Bright white light

More than 20 of Europe’s leading companies and research establishments aim to demonstrate high-brightness white OLED light tiles for use in general lighting by 2008.

More than 20 of Europe’s leading companies and research establishments aim to demonstrate high-brightness white OLED light tiles for use in general lighting applications by collaborating in a new EU project called OLLA.

The OLLA project, which started on October 1st, 2004 and will run for 45 months, will examine the electrical and optical properties of OLEDs, manufacturing principles and system integration issues.

In recent years, OLED technology has improved to the point where it is now possible to envision OLEDs as the next solid-state light source. In order to make this happen, significant advances must still be made in device efficiency, lifetime at high brightness, high throughput fabrication processes, and the generation of illumination-quality white light.

“That’s exactly what we will do in OLLA. We will aim for a lifetime of 10,000 hours – which is 10 times longer than a standard incandescent bulb – and an efficiency of 50 lumens per Watt,” said Peter Visser of Philips, the project manager of OLLA.

With funding of 20 million Euros, OLLA is one of the world’s largest joint research projects on the development of white OLEDs. It is partially funded under the European Union’s 6th Framework Programme.
