Siemens has developed a flexible color display screen that can be printed on something as thin as paper, cardboard, foil, or even plastic. It's also affordable enough — about $52 for 3.2 feet — to be included in everything from books and magazines to tickets and instructions on packaging labels. Apparently this flexi-tech uses "electrochromic substances that change color when an electrical charge is administered, absorbing other light wavelengths than in their original state." (No word on how that charge in gets into the thing.) The most practical use of this is for video instructions on packaging, say for hardware installation or drug dosage. Sounds very cool, especially for people like me who are always too impatient to read the manuals. Word is the technology won't reach the market until 2007.
