By showing off a phone with a flexible screen, Samsung is hinting at a day when we might fold up our large phone or tablet screens as if they were maps.
The Korean electronics company provided a glimpse of such a device at a keynote speech Wednesday at the International CES gadget show in Las Vegas. It's an annual showcase of the latest TVs, computers and other consumer-electronic devices.
This is a Prototype
How it works: The screen uses organic light-emitting diodes, or OLED's. Only a thin layer of these chemicals is needed to produce a bright, colorful screen. They're used in many Samsung phones already, though with glass screens. For the bendable phone, Samsung laid the chemicals over thin plastic instead of glass. That's a trick you can't pull off with liquid crystals in standard displays.
