Apple granted another patent for ‘the most accurate' way to embed fingerprint reader into display
With the iPhone 8 expected to embed a fingerprint sensor into the display to allow much smaller top and bottom bezels, there's no doubt that Apple has the technology required to make this possible. We've seen a steady stream of patents describing different ways to achieve this.
One of the technologies Apple has explored is ultrasonic imaging. A previous patent described this as ‘the most accurate but least common finger-scanning technology,' and a further patent describing this approach has been granted today
Apple says that ultrasonic imaging avoids two common problems experienced with other fingerprint sensors, including its existing form of Touch ID.
