Microsoft files patent for two-screen smartphone

Microsoft has filed a patent for a new hinge design that would connect two screens on a smart phone, Business Insider reports.

In the patent filing, Microsoft says dual-display devices are the next step for smartphones because making screens and phones any larger "is not desirable" for consumers. Per Business Insider, the patent "doesn't mean Microsoft is building a device," but it demonstrates how the company is "looking at the future of smartphones."

• Their design connects the screens using the "Hinge with Free-Stop Function," which allows the phone to lay flat with both screens unfolded.
• In the patent filing, Microsoft says: "With a dual-display device, the mobile phone or tablet can include an open, expanded position where both displays are flush so that the user feels like there is a single integrated display. In a closed, condensed position, both displays are face-to-face so as to protect the displays. In a fully-open position, the dual displays can sit back-to-back so the user needs to flip the device to view the opposing display."
