EU funded project - LEO officially started

LEO focuses on innovative manufacturing concept & routes towards high performance bendable and low cost OLEDs for general and mood lighting

3 Aug 2015 | Editor

The LEO - Low-cost / energy Efficient OLED for lighting has been officially launched. LEO focuses on innovative manufacturing concept & routes towards high performance bendable and low cost OLEDs for general and mood lighting, merging conventional and proven technologies with disruptive approaches (e.g. substrate, architecture, hybrid processing, layouts).

R&D activities will be ramped-up from lab scale feasibility to pilot line scale demonstration, delivering lighting systems with the help of external lighting manufacturers - Artemide, Technology Luminaires.

The project targets the introduction of novel materials combinations (conformable & functionalised metallic substrate, Indium free electrodes and solution-processable organic materials) in large area colour tuneable top emission white OLEDs. Besides dry processing of large area tandem stacks (> 500 cm2), a novel hybrid process flow will be set-up whereby stacks will be wet processed up to the 1st emitting layer prior device completion by dry processing.

With common and innovative building blocks (substrate with integrated interconnecting, 80% transparent top electrode, 1E-6 g/m2/day WVTR scratch resistant thin film encapsulation, 50% out-coupling efficiency), these two complementary approaches will lead to demonstrations of large area warm/cold white macro-pixels and hybrid full colours RGB OLEDs.

LEO will address cost reduction at materials and process levels which represent more than 80% of the total cost of OLED lighting devices, according to a recent study. Leverage will be sought at mostly all layers of the stack with cost impacts at materials, device and system scales.
