Structural color, which is the foundation that makes things like a peacock's tail feathers appear iridescent, has been an area of study for scientists as they try to adapt it for use in everyday ...

Researchers at HP Labs are testing a flexible, full-color display that saves power by reflecting ambient light instead of using a backlight. The prototype display’s pixels are controlled by ...

Liquid metal controlled by low voltage reversibly switches color and infrared response in nanoscale surfaces, enabling low power reflective displays, sensors, and optical security features. (Nanowerk ...

Electronic paper that reflects light, instead of filtering it from a backlight, as most conventional displays do, is easy on the eyes and saves on battery life. But this reliance on ambient light ...
