Patent application hints that Microsoft's folding phone could have three screens
The images from this patent application show two large displays on either side of the device. In the middle, where the outer screens fold in, is a narrow display that would show information "that is coupled to other screen regions." This would include virtual controls, time, messages, notifications and calls. According to the patent application, the information found on the third screen depends on the state of the hinge. In other words, what you see on the hinge screen will depend on whether you have the device opened fully in tablet mode, "tent mode," or have the screens opened like a book.
We recently told you about some rumored specs for Samsung's foldable Galaxy X phone, expected now to be unveiled next February. This device would also carry three screens, but unlike the images we see from Microsoft's patent application, the Galaxy X would have two 3.5-inch OLED panels inside the device and a similar screen found on the outside. The latter would be used to control the unit when it is in "smartphone mode."
Microsoft's patent application was originally filed on November 9th, 2016 and is titled "Device having a screen region on a hinge coupled with other screen regions." The applicant is Microsoft Technology Licensing, LLC. You can check out some images from the patent application by clicking on the slideshow below.
