Paper-Thin Electronic Display
Siemens is developing a paper-thin electronic display so cheap that it could replace conventional labels on disposable packaging. This could tranform consumer-goods packaging from the fixed, ink-printed images of today to a digital medium of flashing graphic and text that displays prices,special offers or alluring photos— all blinking on miniature flat screens.
The display, composed of polymerbased photochromic material, shows digital text and images when prodded by an electrochemical reaction powered by a low-voltage charge. when the electric charge is removed , the chemical reaction is reversed, and the electronic ink is no longer visible, which is how a flashing effect is created. The power source is commercially available, ultra-thin batteries and the images are stored by electronic memory strips.
