Following iPhone 5S adoption of dual-flash LED, smartphones are expected to set off a new dual color flash LED trend. The market is very optimistic about growth in demand for flash LED. The two main supply chains for flash LED are separated into vertical chip manufacturers including Osram, Cree, and Samsung and flip chip manufacturers, such as Philips Lumileds, and Nichia. Taiwanese manufacturers Epistar and Genesis Photonics Inc. (GPI) are also following suit to grab flash LED market shares.
