Microsoft could be developing a tri-fold Surface phone
Microsoft could be developing a "multi-panel" device with a tri-fold design.
The U.S Patent and Trademark Office (USPTO) granted Microsoft a patent which is titled "multi-panel device". The application, which was filed three months prior to the announcement of the Surface Duo, illustrates a three-display device where the first and third displays can pivot such that all three displays are stacked on top of each other.
Microsoft is not the only company looking into a tri-fold device; Samsung Display published sketches on its blog in November 2020 that show a device with a tri-folding display, and another device with a rollable display. GizmoChina reported in April that Samsung is working on a triple-folding tablet for release as early as Q1 2022.
