As developed the world's first blue LED and long-term commitment phosphor research and development enterprise, Nichia has a sapphire substrate, epitaxial growth, blue LED, white LED, phosphor, etc. Many of the underlying patent. On this basis, Nichia in the whole industry chain gradually establish a strong patent portfolio, patented technology covering the substrate, epitaxy, chip, package, and application areas of the LED industry chain. Amount from the application point of view, Nichia patent application mainly in the areas of packaging and epitaxy, both the proportion reached 38% and 27%, respectively, followed by the application of the field, and the least amount of patent applications in the field of drive. Package of patents in the field is mainly concentrated in the package and substrate technology branch. More epitaxial patent in the field of application for technical branch in the group III-V, while the ohmic contact layer and the current spreading layer and other applications for technical branch less. The more applications display and backlight technology branch applications, and other branches of a significant number of patents layout. The chip field electrode design and reflective film technology branch applications more. Substrate patents in the field of 55% technically in the sapphire substrate. Nichia LED industry chain to establish a relatively complete patent layout.
