Last week the U.S. Patent & Trademark Office published a patent application from Samsung that reveals their ongoing work on developing a foldable smartphone. While Samsung has been working on flexible and foldable devices for years, as noted in our extensive archives, flexible OLED displays have greatly advanced as noted recently at a German trade show. Earlier today Patently Apple posted a report about silver nanowire-based flexible touch display technology. The technology will allow OEMs to design phablets and tablets that could be folded and put in your pocket. Samsung's latest invention plans on doing just that as noted in our cover graphic. The backside ports are only seen when the phone is folded. For more graphics covering this concept along with a new charging station, see our Patently Mobile report here.
