April Flowers for redOrbit.com - Your Universe Online Peacock feathers have a beautiful iridescence about them – a sheen that shifts colors depending on your perspective. Nature created this color shifting with relative ease, it seems, but it has been a nuisance for engineers trying to reproduce this unique color mechanism to make high-resolution, reflective color display screens. A new study from the University of Michigan reveals researchers have found a way to lock in so-called...

In a step toward more efficient, smaller and higher-definition display screens, a University of Michigan professor has developed a new type of color filter made of nano-thin sheets of metal with precisely spaced gratings.The gratings, sliced into metal-dielectric-metal stacks, act as resonators. They trap and transmit light of a particular color, or wavelength, said Jay Guo, an associate professor in the Department of Electrical Engineering and Computer Science. A dielectric is a material...
