Merck signs silicate phosphor white LED deal with Tridonic
Along with Japan’s Toyoda Gosei Co. Ltd., Germany’s Leuchtstoffwerk Breitungen GmbH, and Litec GbR, Tridonic holds basic patents relating to a technology to generate white light using blue LEDs and novel yellow silicate phosphors.
The 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.
Tridonic is now granting a material license to Merck to manufacture and market the silicate phosphor materials for potential use in white light LEDs. The license agreement gives Merck full potential to manufacture and offer silicate phosphors for use in white LEDs.
Merck noted that its customers can purchase phosphor materials manufactured under the Tridonic license.
