LG’s new fingerprint sensor can neither be felt nor seen

Life may be sweeter under the sea, but it’s clearly safer under the screen. As biometric security becomes more common on our devices, the problem of placement has become a proper predicament. Whereas companies like LG and Huawei have been keen to keep fingerprint readers on the back – where they can’t be seen – others like Samsung, Apple, and now HTC are placing them on the bottom bezel. Then there was Sony which decided to slide the unit off to the side. LG Innotek however, may have solved the problem entirely: put it under the screen.

By cutting a 0.01 inch (0.03mm) sliver out of the lower backside of the “coverglass”, LG was able to place a fingerprint sensor inside “[sic] using their supreme precision and combination technology.” The result is a module that “[sic] gives the freedom of the smartphone design and even enhances the user-friendly function, for example, waterproof or protection from scratches.”
