Samsung receives patents for a folding phone and a transparent smartphone display
Unlike a regular hinge, the phone would be equipped with a special hinge that would respond to the touch of a sensor. One the latter is activated, the device would fold into configurations that could be preset by the manufacturer. Images that are part of the official patent documentation show a screen in landscape mode split in half by a fold. One drawing shows apps on both sides of the folding display, while another sketch shows an open email on the left side of the screen, and app icons on the right side. In a subsequent image, the email takes up the entire screen. That would seem to indicate that users will be able to choose one of the images on either side of the screen and make it fill the entire display. It sounds like the landscape version of multi-window.
Samsung also received a patent yesterday for a transparent smartphone screen. The company unveiled a transparent television screen in 2015, and we'd imagine that the transparent smartphone display will be similar, albeit much smaller (obviously). The see-through screen could also allow for the use of AR without employing a camera to incorporate the real world background used in the feature.
