eldavojohn writes: A device like that of Dick Tracy's watch has been announced from HP with a target user base being the US military. CNN describes it as 'a flexible display that shows maps and other strategic information to soldiers in remote combat fields. The watch's screen will be made of plastic and it will run on solar energy, making it less likely to malfunction or run out of power in a tense scenario.' HP says a prototype will be done within a year. This new device hinges on recent display technology that HP says it has been developing for ten years. The flexible displays are a mere 50 microns thick.
