Yes, you read it right. Thanks to LG, this may soon become a reality. LG Innotek, a subsidiary of LG, has successfully developed such a design wherein the fingerprint sensor is placed below the display.
The way fingerprint modules are placed in current smartphones, they are prone to scratches as the users are required to make physical contact with them to authenticate. With the new design, this problem can be easily solved. The display already has a protective covering (like Gorilla or Dragontrail glass), and the fingerprint sensor can sit under it unharmed. Also, the OEM’s need not worry about the fingerprint module when making IP67 certified (waterproof) devices.
To house the sensor, a 0.3 mm thick cut is made on the lower backside of the glass. The sensor is then attached to the display with the help of an adhesive.
If we talk about accuracy, this design is comparably accurate to the ones available today. The probability that an unauthorized person will gain access to the device (via the fingerprint sensor, of course) is as low as 0.002%.
Effectively, all this means that we will be able to unlock the device by just placing our fingers on the display. Even though this sounds interesting, it is just the beginning. However, the future looks promising. We’ll have to wait and see how the events unfold.
As far as their commercial availability is concerned, there is no news yet. But given the increasing demand of a fingerprint sensor in portable gadgets and the rise of digital payments, the day is not too far.
