Apple’s collapsible iPhone will include two glass panels like Surface Duo, rather than a collapsible panel like Samsung’s Galaxy Fold, but that doesn’t mean the company won’t get involved in borderless collapsible devices,media reported. In fact, the company proposed a unique way to fold glass screens in a patent application filed in March 2020.
Apple recommends cutting a series of grooves inside the glass surface in the patent filing, which would give the glass the flexibility to bend without breaking, a process known in wood called Kerfing, which can be seen in the following video:
Apple has proposed filling the grooves with the same refractive index as glass, so that the grooves are almost invisible to people.
The grooves are of course only in the folding area of the glass, and the rest of the display is the same as a normal display.
Apple’s method of using truly flexible materials may not be mechanically complex, but it is not too difficult to manufacture.
