GaN-on-Silicon Substrate Patent Investigation - Knowmade & Yole See More Players on the Playground
GaN-on-Silicon Substrate Patent Investigation - Knowmade & Yole See More Players on the Playground GaN-on-Si technology appeared naturally as an alternative to GaN-on-Sapphire—the main stream technology for LED applications. Today, despite potential cost benefits, the mass adoption of GaN-on-Si technology for LED applications remains unclear. Most major LED makers have a patenting activity related to GaN-on-Si technology, but so far, few have made it the core of their strategy and technology roadmap. Contrary to the LED industry, we expect GaN-on-Si to be widely adopted by Power Electronics and RF applications because of its lower cost and CMOS compatibility. Read more »

Research and Markets Offers LED Lighting - Key Patent Analysis: Remote Phosphor
LEDs, which are semi-conductor devices that convert electricity into light by the properties of compound semi-conductors, have higher energy efficiency and cost less for replacement due to longer lifetimes than existing lighting systems, and have high resistance to impact or vibration. Furthermore, LEDs have advantages in terms of energy saving and protection of the environment since they do not use toxic substances such as mercury, which give an impetus to their market entry as new lighting systems to replace existing lighting systems.
