Qualcomm's new fingerprint sensors goes through Display, Metal and Glass

At MWC Shanghai, 2017, Qualcomm introduced the Snapdragon 450 Mobile Platform for mid-range devices. Additionally, it also unveiled its new advanced fingerprint scanning and authentication technology. Dubbed Qualcomm Fingerprint Sensors, the new ultra-sonic fingerprint solution brings improved feature to the previous generation Qualcomm Snapdragon Sense ID fingerprint technology.

Qualcomm's Fingerprint Sensors consists of sensors that work with Display, Glass and Metal, detection of directional gestures, and underwater fingerprint match and device wake-up. This will allow device makers to put sensor below a device's display, on the back or under the screen.

It is also the first integrated ultrasonic-based mobile solution to detect heart beat and blood flow for improved mobile authentication experiences.

Qualcomm's new fingerprint sensor for Display is capable of scanning a fingerprint through OLED display stacks of up to 1200um, along with enrolling and matching. The sensors for Glass and Metal are touted to be the first commercially available solutions to scan through up to 800µm of cover glass and up to 650µm of aluminium, an improvement over the previous generation’s 400 µm capability for glass or metal. The new fingerprint sensors also support IP68 water proof devices, so they will work when your underwater.

The new sensors are designed as both an integrated solution with Qualcomm Snapdragon Mobile Platforms, and as standalone sensors that can be used with other mobile chipsets.

Qualcomm and Chinese smartphone maker vivo also showed off a modified version of the vivo X6 Play smartphones using Qualcomm's new Fingerprint Sensor for Display technology, to demonstrate its capabilities.

Qualcomm Fingerprint Sensors for Glass and Metal are expected to be available to OEMs this month, and are expected to arrive in commercial devices in the first half of 2018. Qualcomm Fingerprint Sensor for Display is expected to be available for OEMs to evaluate in the fourth quarter of 2017.
