LG fingerprint sensor sits beneath smartphone screen

Fingerprint readers are increasingly ubiquitous in smartphone design, so much so that the question is not whether to include one, but where to put it. Where some manufacturers have chosen to add readers into buttons on the front or raised sections on the back of their devices, LG Innotek has a new idea — put it under the phone's screen. The LG affiliate announced today that it had developed a new fingerprint sensor that it has slotted into a tiny 0.01-inch (0.03 milimeter) space cut into the underside of smartphone cover glass, allowing device designers to incorporate fingerprint readers without dedicated buttons, pads, or other exposed elements.

Fingerprint modules regarding smartphones typically require you to press your finger roughly a raised button, meaning they must be mounted externally. LG's South Korean society Innotek is innovating upon this stomach, even though, and has created a fingerprint sensor that doesn't require a button at all and is mounted beneath the screen, for that defense offering the functionality without interfering behind the form.

With the sensor out of the way, companies can be more pardon once their smartphone designs.   The sensor is said to be safe thanks to tall-strength lid glass which protects it from water and scratches, even if a proprietary adhesive keeps it safe even after high impact. It's also said to have an totally low traitorous appreciation rate of 0.002%.
