Merck announced that it has entered into a license agreement with Tridonic Jennersdorf (Tridonic) covering silicate phosphors for use in white light LEDs. Along with Toyoda Gosei (Japan), Leuchtstoffwerk Breitungen (Germany), and Litec (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.
