NRI led scientists develop filter for brighter LCD displays

Researchers led by Utah University electrical and computer engineering associate Professor Rajesh Menon, have developed a polarising filter that can result in mobile device displays that last longer on a single battery charge and cameras that can shoot in dim light. Polarisers are indispensable in digital photography and LCD displays but they block light, wasting energy and making it more difficult to photograph in low light, but this new concept in light filtering can perform the same function as a standard polariser but allows up to almost 30 percent more light to pass through. Menon said the first marketable applications of this technology could be available in five to ten years. He said the technology could also be a boon for photographers who want to bring out more detail in their pictures when shooting in low light situations, and for scientists using microscopes and telescopes to visualise obscure phenomena.
