Apple, get out your checkbook and buy all of LG Innotek's new smartphone glass with hidden fingerprint sensor.

LG Innotek today announced an under glass fingerprint sensor module. No more ugly physical sensor button. LG Innotek managed to hide the fingerprint sensor under glass. 

This module gives the freedom of the smartphone design and even enhances the user-friendly function, for example, waterproof or protection from scratches.

Previous ‘button type’ modules required you to press a finger on a raised square or circular button for your fingerprint to be read exactly, so the sensor was usually mounted on the front, rear or side buttons of a smartphone.

LG Innotek cut a shallow furrow of 0.01inches (0.3mm) 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.

With this module, the sensor is not exposed to the outside of the device, so manufacturer can produce a sleek designed smartphone. Fingerprint recognition area also can be indicated by various patterns up to design of complete product.

High-strength cover glass protects the sensor and prevents it from coming in direct contact with water or damage from scratches.

At the same time, the new module secured the fingerprint recognition accuracy compared to the button type. The new module has a false acceptance rate (FAR) of 0.002%. The FAR is the probability that the system falsely recognizes someone else's biometric information as that of the user.

LG Innotek developed a proprietary adhesive to be used to attach the sensor to the glass, securing the commercialization scale of the durability including high impact absorption.

The adherent side of the sensor and glass is only 0.0098inches (0.25mm) thick, but it endures impact of 4.6 oz (130grams) of the steel ball dropped from 7.9inch (20cm).

Changhwan Kim, Head of the company’s R&D Center said, "We are concentrating on all our resources to the development of the differentiated technology based on the creation of customer values.” “We will continue to provide convenient, safe, and pleasant user experiences by launching innovative product.”

Can't wait to see the new LG Innotek hidden Fingerprint sensor on an iPhone.
