dual-screen foldable tablet

Microsoft is exploring a new hinge design for a foldable dual-screen mobile device that doubles as a laptop with a virtual keyboard. Microsoft is not the only company working on foldable devices, Samsung, Sony, and Lenovo are all on the same page

The patent, first spotted by MS Poweruser, has again fanned rumors that Microsoft is still working on a foldable device to be released under the Surface brand.

The design in the new patent isn’t too unlike Microsoft’s abandoned Courier project and comes as rumors persist about its work on Andromeda, a dual-screen foldable device said to run on a version of Windows codenamed Andromeda OS. It’s possible Andromeda could be an ARM-based device.

Like the hardware shown in the patent, the foldable Andromeda is said to be designed to mimic a notebook, offering Microsoft a new class of mobile device in addition to tablets and phones. Microsoft filed a similar foldable device patent with a flexible hinge earlier this year.

This patent goes into more details about the mechanics of the hinge. Microsoft describes its “hinged device” as having two “self-regulating” hinges that secure two portions of a device into various positions, not unlike Lenovo’s Yoga. The hinges are placed on opposite edges of the device and hold the two screens in place using a gear system.

Microsoft’s foldable mobile device doubles as a tablet and notebook.


Folded flat, the device generates a unified user interface across the two displays to offer a tablet experience. When in a ‘notebook’ position, it creates a virtual keyboard and touchpad on the bottom screen and a usual notebook display on the top screen. The user can then fold the device closed when not in use, or place it in an “alarm clock orientation” when it’s idle.

Both hinge patents were invented by Kabir Siddiqui, who’s been responsible for several hinge designs at Microsoft. Microsoft filed the patent in October 2016, and it was published on December 14 this year.

It’s not clear whether Microsoft will launch a device that looks like the one in this patent. It could, such as, use the hinge design in future generations of existing Surface hardware.
