OLLA project delivers Europe’s most efficient OLED lighting tile
The European OLLA consortium is making progress towards its target of a high efficiency OLED light source with long lifetime.
Partially funded under the IST priority (Information Society Technologies) of the European Union’s 6th Framework Programme (FP6), OLLA stands for "high brightness Organic LEDs for ICT & next generation Lighting Applications." The consortium consists of 24 entities (universities, research institutes and industrial partners) in 8 European countries.
OLEDs are currently used for small display applications like MP3 players, but can also be used as a flat and efficient light source, and this is the focus of OLLA. The project's goal is to demonstrate in 2008 a long-lifetime and highly efficient white OLED light with the following specifications: 50 lm/W efficacy, lifetime of 10,000 hours from an initial brightness of 1000 cd/m2, with a tile size of minimum 15x15 cm2. The latest results show that OLLA is progressing towards these targets.
