Apple's 'iPhone 7' hasn't arrived yet but that hasn't stopped analysts from predicting that an 'iPhone 8' will ditch the iconic Home button. Conventional wisdom has it that 3D Touch will simulate Home button presses while fingerprint recognition should be realized by incorporating the Touch ID sensor into the display itself.
What conventional wisdom doesn't help explain is how such a technology might work. Well, now we know: LG announced its Innotek division has achieved a major technological breakthrough in producing the world's first in-screen fingerprint scanner.
“LG Innotek cut a shallow furrow of 0.01 inches (0.3 mm) thick on the lower backside of the cover glass and installed the fingerprint sensor inside of it with using their supreme precision and combination technology,” explains the company.
