In 2017 and 2018 Samsung filed for patents covering a smartphone with a frame and display that could expand as presented below. In some ways the invention sounds more practical than foldable smartphones in the shorter term until a foldable smartphone could be as a thin as a single smartphone is today.
Yesterday the U.S. Patent and Trademark Office published granted patent 10,025,355 for Microsoft that is focused on the expandable frame and display concept as presented in the patent figures below.
Samsung's idea was for both left and right sides of the smartphone to expand outwards whereas Microsoft's design is simply expanding the display by pulling the right side of the phone out as shown in FIG. 1 below.
Microsoft's patent FIG. 1 presented above illustrates examples of a flexible display extendable assembly. The smartphone could appear as a single display and then expand to almost a double sized display to watch mobile TV with.
The extendable assembly includes an extendable mechanism that is coupled in a second housing part of the extendable electronic device and to the slideable display guide. The first and second housing parts of the extendable electronic device slide-engage relative to each other. The display sits under the frame in a roll that could expand and detract as needed and in tune with the movable frame.
Microsoft's patent FIG. 5 illustrates example method(s) of a flexible display extendable assembly.
Microsoft originally filed for the patent back in January 2016.
