Smart­phones With Fin­ger­print Sen­sors Under the Dis­play Com­ing in 2018


Qualcomm has announced an advance fingerprint scanning and authentication technology that will be able to scan fingerprint through a display, glass or metal surface and will also be accessible during underwater operations.


The Qualcomm Fingerprint sensors are an enhanced version of Qualcomm Snapdragon Sense ID fingerprint tech and will also be able to detect heartbeat and blood flow.

The ultrasonic-based solution for mobile devices for Qualcomm is a welcome development for all those craving fingerprint sensors embedded in the display when the Galaxy S8 was launched.

“We are excited to announce Qualcomm Fingerprint Sensors because they can be designed to support sleeker, cutting-edge form factors, unique mobile authentication experiences, and enhanced security authentication,” said Seshu Madhavapeddy, VP of Product Management, Qualcomm Technologies.

Going by the announcement, not only will this development open an avenue for smartphone manufacturers to embed the fingerprint sensor beneath the display, but they can also embed it underneath a glass or aluminium back casing.


“This provides OEMs and operators with the ability to offer truly distinct, differentiated devices with added value on truly groundbreaking new devices,” he added.

The new tech is capable of scanning through an OLED display to upto 1200 μm (micrometer), 800 μm through Glass and 525 μm through aluminium.

Qualcomm’s fingerprint sensors for glass and metal are compatible with the recently announced Snapdragon 660 and 630 mobile SoC and will also work on the future Snapdragon mobile platforms.

The fingerprint sensor tech isn’t limited to being integrated with Qualcomm’s Snapdragon SoC, but will also be available as a standalone sensor that can be used alongside non-Snapdragon platforms.

The glass and metal sensors will go on the shelf for OEMs to make use of by the end of this month and are expected to be seen being used in commercial devices in 2018. The fingerprint sensors for display will be available by the end of 2017.
