Apple and other manufacturers may introduce new products with curved touchscreen displays next year, DigiTimes reported on Monday. Apple has reportedly contacted its iPad and iPhone glass suppliers, Lens Technology, G-Tech and Fuji Crystal, and will supply them with equipment for polishing glass. Curved glass displays are not typically used on smartphones, although Google and Samsung did equip the Nexus S with a concave screen and it was noticeably more comfortable during phone calls. The curves also protect the screen from scratches when a phone or tablet placed face-down on a surface. Dell also went with a curved display on its Venue Pro Windows Phone, though it opted for a concave curvature. Corning, which provides scratch-resistant screens for a number of smartphones, has already developed a curved version of its popular Gorilla Glass, but it is unclear if that screen will be used on future Apple products.
