Apple has patented a home button that is part of the phone's display, with an embedded fingerprint sensor used for biometric authentication.The design, which is rumoured to be planned for use in the iPhone 8, involves IP covering a fingerprint sensor capable of gathering accurate readings through structures like a device screen, reports Apple Insider.As published by the U.S. Patent and Trademark Office, the tech described in Apple's U.S. Patent No. 9,460,332 for a “Capacitive fingerprint sensor including an electrostatic lens” offers a solution to a major design hurdle presented with the rumored design of next year's iPhone.The patent furthers reports that the 2017 iPhone will do away with the iconic home button to make way for a “full-screen face” comprised of an edge-to-edge OLED display. Instead of the physical Touch ID module seen in contemporary iPhone and iPad devices, Apple is said to be working on a virtual button which presumably carries over the same features and functions.The home button has been a mainstay of Apple's portable device lineup since the first iPhone launched in 2007.
