Excyton, a startup based at KAUST, has developed a novel display technology called “TurboLED” that reduces power consumption by 50% and increases the color range rendered on displays to 76%. The technology utilizes a six sub-pixel format (light and deep RGB) compared to the standard three, saving energy by using lighter colors most of the time. Excyton received $2 million in funding from KAUST Innovation Ventures and collaborated with KAUST to develop the technology. Why it matters: This innovation could significantly improve the battery life of mobile devices while also enhancing display quality, providing a competitive advantage for devices manufactured in the region.
KAUST and KACST researchers have developed a nanoPE nanoplastic that improves LED streetlight energy efficiency by enhancing thermal radiation emission and reducing LED temperature.
