Together with Toyoda Gosei in Japan, Leuchtstoffwerk Breitungen and Litec GbR in Germany, Tridonic Jennersdorf makes up the B.O.S.E. Consortium which owns basic patents for a technology that generates white light with blue LEDs and yellow silicate phosphors. In Tridonic’s view, the smartphones that form the subject of the legal action infringe several patents held by the B.O.S.E. Consortium.
Silicate-based white LED technology enables the manufacture of white LEDs with high accuracy and high brightness. Primary applications of such LEDs include the backlights of liquid crystal displays used in smartphones, laptops, GPS systems and other display products, which means this technology is of relevance to a substantial share of today’s LED market. To make this white LED technology available to the LED industry, the B.O.S.E. Consortium offers licensing arrangements for its use. The B.O.S.E. Consortium has already concluded licensing agreements with more than 40 LED manufacturers worldwide.
