Flat screen displays currently used in computer monitors, television sets and numerous other electronic devices are all built on a glass base. Most use liquid crystal devices (LCDs), which filter light from behind to form an image. But the glass substrate makes LCD displays rigid and fragile, limiting their use. Now display manufacturers are working to develop a new generation of robust, flexible displays that can be curved to fit the shape of a product or even rolled up like a magazine. The question is, which of the technologies under development is the best?
