Applied Materials Inc., Merck KGaA and the Braunschweig University of Technology (TU-BS) have been awarded a grant for OLED R&D by Germany's Federal Ministry of Education and Research (BMBF). They will develop processes to lower the cost of manufacturing OLED lighting for general illumination applications. Applied will spearhead the three-year project, named Light InLine (LILi) which will be centered at Applied Materials' advanced development facility in Alzenau, Germany. Merck is a manufacturer of OLED materials and TU-BS is an internationally recognized center for OLED research.

Fabricated on sheets of glass, OLED lighting tiles can emit white light that is brighter, more uniform and more energy efficient than fluorescent light fixtures, making them well-suited for ceiling lights in homes and offices. While a number of OLED products have been developed in recent years, key challenges such as limited lifetime and high costs must be addressed for the technology to be widely adopted. The LILi project aims to address these challenges by developing large-area manufacturing processes using high-performance organic materials and efficient device design.

"Solid-state lighting is an important component of an energy-efficient future," said Mark Pinto, senior VP, corporate chief technology officer and general manager of Applied's energy and environmental solutions organization. "OLED technology aligns well with our equipment used for manufacturing flat-panel displays. We've already delivered a system that is now in pilot manufacturing at a leading European lighting manufacturer. Through the LILi project, we expect to further optimize this technology to increase the quality and drive down the cost for OLED lighting applications."

"Merck has a wealth of experience in developing and scaling up the complex organic compounds that are essential for stable and cost-effective OLED manufacturing," said Udo Heider, VP of liquid crystals/OLED at Merck. "The LILi project is a great opportunity for us to test new organic materials with state-of-the-art manufacturing equipment in order to validate their stability and performance on large area substrates."

"Innovation in OLED technology is one of the primary focuses of our institute," said Wolfgang Kowalsky from TU-BS. "We're pleased to partner with Applied Materials and Merck to evaluate how our new high-efficiency OLED lighting device structures will perform in an industrial-scale environment."

The total cost of the OLED project will amount to approximately $ 11.18 million, which includes $ 4.87 million to be provided by the German Federal Ministry of Education and Research and $ 6.31 million to be contributed by the industry partners. The grant seeks to support OLED collaborative research and encourage OLED manufacturing in Germany.
