Microsoft patent images reveal folding Surface tablet9
The new sketches go into detail as we can see the individual parts making up the hinge that allows the device to fold. In addition to what looks to be a set of mechanical hinges at the top and bottom of the screens, a number of magnets on both sides of the tablet's spine helps the device fold.
Different setups for the device include tablet mode, tent mode, laptop mode, and folded mode. According to a report published today, the device will run a special Windows 10 version codenamed Andromeda. The folding tablet will reportedly include a note taking app that will allow the user to use both screens as though they were writing in a regular notebook. And regardless of the mode that the tablet is in, Windows 10 will make the proper adjustment using CShell, Microsoft's new Windows Shell.
There is no word on when we might see this device hit the light of day, that is, if it ever does.
