Both color and saturation can be controlled
Philipsâ€™ technology allows different colors of ink to be built into one layer with each color controlled separately
Philips e-skin technology features a gradient of grey levels from a highly transparent optical state (left) to full black (right). This enables future applications like smart windows
Rather than using e-paper technology just for displays, the research arm of Dutch technology company Philips Electronics has developed a relatively cheap, light, thin and energy efficient means of turning the whole of the surface of a device into a digital canvas. E-skin technology could be used to change the color of a mobile phone when a call comes in, alter the appearance of a kettle when the water is boiling or even be applied to wallpaper so you can redecorate your room at the flick of a switch.
