Next-gen e-readers: Improved 'peacock' technology could lock in color for high-res displays

Iridescence, or sheen that shifts color depending on your viewing angle, is pretty in peacock feathers. But it's been a nuisance for engineers trying to mimic the birds' unique color mechanism to make high-resolution, reflective, color display screens. Now, researchers have found a way to lock in so-called structural color, which is made with texture rather than chemicals.
