OLED-TV Display/Monitor Technology News

Europe's three-year-old Organic LEDs for ICT and Lighting Applications (OLLA) project looks to develop high-brightness OLEDs for information and communication technology (ICT) and next-generation lighting. OLLA said in May that it had prototyped a white-OLED light source with an efficacy of 25lumens/W and a lifetime of more than 5,000hrs from an initial brightness of 1,000cd/m².

"We doubled the efficiency and expanded the lifetime five times compared with a conventional, tungsten-filament bulb," said OLLA project manager Peter Visser. "In a few years' time, we expect OLED sources to be as efficient as a compact fluorescent source."

The OLLA project, which has just passed the halfway point of its funded duration, has a final efficacy target for OLED lighting of 50lumens/W, combined with a lifetime of 10,000hrs at 1,000cd/m² initial brightness.

The white-OLED light tile was designed at Philips Research Labs—a vocal OLED proponent—from a mixture of fluorescent and phosphorescent OLED materials within project partner Novaled AG's proprietary PIN (p-doped, intrinsic, n-doped) structure.

About the OLLA project:
OLLA is a joint research project dedicated to the development of white OLEDs for general lighting applications.
Goal of the OLLA project is to demonstrate in 2008 long-life and highly efficient white OLED light with the
following specifications: efficacy of 50 lm/W, lifetime of 10.000 hours from an initial brightness of 1.000 cd/m2, with a tile size of minimum 15x15 cm2.
The consortium consists of 24 entities in 8 European countries. OLLA is partially funded under the IST priority (Information Society Technologies) of the European Union’s 6th Framework Programme
