Merck and Tridonic Enter Into License Agreement for White LEDs

Merck, a leading company for innovative and top-quality high-tech products in the healthcare, life science and performance materials sectors, announced today that it has entered into a license agreement with Tridonic Jennersdorf GmbH (Tridonic) covering silicate phosphors for use in white light LEDs.

Along with Toyoda Gosei Co. Ltd. (Japan), Leuchtstoffwerk Breitungen GmbH (Germany), and Litec GbR (Germany), Tridonic holds basic patents relating to a technology to generate white light using blue LEDs and novel yellow silicate phosphors. This combination of silicate phosphors applied to blue LED chips enable manufacturing of packaged white LEDs with high accuracy and high brightness. Primary applications include backlights for cell phones, laptops, GPS and other small displays, which account for a high share of today’s global LED market.
