Imagine sitting out in the sun, reading a digital screen as thin as paper, but seeing the same image quality as if you were indoors. Thanks to research from Chalmers University of Technology, Sweden, it could soon be a reality. A new type of reflective screen—sometimes described as electronic paper—offers optimal color display, while using ambient light to keep energy consumption to a minimum.
Traditional digital screens use a backlight to illuminate the text or images displayed upon them. This is fine indoors, but viewing such screens in bright sunshine is difficult. Reflective screens, however, attempt to use the ambient light, mimicking the way our eyes respond to natural paper.
