While it does look similar to the clamshell-style foldable phone, the other images (such as Fig. 1) suggest that it will include other components such as joysticks. Meanwhile, Fig. 2, and Fig. 3 gives us an idea of where these raised parts are located so that the two halves can be shut.
It is clear that Samsung is describing a foldable gaming console, which means that it will have to offer some protective technology to keep the display safe while it is in use. Fig. 3 shows what appears to be a crease on the display
When the device is folded (Fig. 11 and Fig. 12) some buttons and controls might be visible on the sides of the device, according to the images in the patent document. Meanwhile, Fig. 13 gives us a clear look at the hinge that connects both halves of the folding device.
While the appearance of a patent document is no indication of whether Samsung will actually launch a product that is described in the document, it would be interesting to see how such a device would fare in the market.
