We’ve seen speculation and rumor that Apple would implement an under-display Touch-ID sensor in at least one of the newest iPhone models. We’ve also seen reports that their testing may not be going as well as they’d hoped. Apple obviously isn’t the only one working towards this goal, as Vivo also plans to release a phone with an under-display fingerprint scanner, which we’re about to learn quite a lot more about. Today at Mobile World Congress Shanghai, Qualcomm officially announced their newest fingerprint scanners, including sensors capable of reading through display glass, and reading through thick glass or metal.
Qualcomm’s announcement lets it be known that it’s their tech powering the Vivo XPlay 6 fingerprint scanning technology and that their newest scanners are better at reading through various materials than any other scanners to date.
Qualcomm Fingerprint Sensor for Display is the mobile industry’s first commercially announced multi-functional ultrasonic solution capable of scanning through OLED display stacks of up to 1200um, along with enrolling and matching, and Qualcomm Fingerprint Sensors for Glass and Metal are the first commercially announced to scan through up to 800 µm of cover glass and up to 650 µm of aluminum, an improvement over the previous generation’s 400 µm capability for glass or metal.
As if the under-material properties of these scanners weren’t enough, they’re also capable of handling gestures, underwater unlock, and heartbeat and blood flow detection.
These scanners are optimized to work with Qualcomm Snapdragon Mobile Platforms, as one would expect, though they will also work as standalone sensors with other non-Snapdragon systems. Qualcomm’s expected rollout for the sensors does seem to put Vivo, or any other OEM’s potentially behind Apple if Apple is, in fact, able to incorporate an under-display fingerprint sensor in any of their new iPhones before the end of the year.
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.
Either way, it’s nice to see this type of tech isn’t too far off, and we should start seeing it in phones one way or another in the very near future.Source: QualcommNews
