HTC Corporation filed a U.S. patent application, recently published as publication no. US 2020/0267245 for a foldable smartphone. The publication shows a mobile device with a detailed hinge mechanism in the middle of the display such that the display is folded outwards and remains visible (in two halves) when the device is folded to close.  There are at least a few foldable phones currently on the market, so it would be interesting to follow the prosecution of HTC’s patent application.
