As shown in the iPhone -7-commercial-esque video above, Qualcomm's in -
display ultrasonic fingerprint scanner is not only secure, but it could revolutionize the way smartphones look and function: bezel-less designs will continue to prevail, water - and dust - proofing will become easier, and — this is what excites me the most, honestly — wet fingers will work just as well!
Not exact matches
Apple might just show the world how to do it in their upcoming iPhone 8, but assuming that Apple didn't just find the holy grail of
ultrasonic fingerprint sensors and make
fingerprint sensors under the
display work as fast as conventional ones, are you prepared to sacrifice unlock speed, or would you rather have a faster conventional
fingerprint sensor on the back?
vivo and Qualcomm have built a prototype to showcase the latter's latest
ultrasonic fingerprint scanner, capable of working through
displays and metal backs.
While we previously predicted that Samsung's new flagship Galaxy Note 9, due out in 3Q18, will come equipped with an under -
display fingerprint recognition function, we now believe Samsung will cancel this feature on Note 9 because both
ultrasonic (provided by Qualcomm) and optical (provided by Samsung LSI, Goodix, Egis, and Synaptics) solutions can not meet Samsung's technical requirements.

In July, Qualcomm and Vivo teamed up to demo an
ultrasonic in -
display fingerprint sensor on a prototype Vivo smartphone, the first of its kind.
Like Qualcomm's, the Vivo Under
Display uses
ultrasonic technology, which uses sound waves to capture 3D images of
fingerprints.
The Qualcomm's sensor for glass will be the first commercially announced
ultrasonic fingerprint scanner that will be able to scan
fingerprints through OLED
displays.
Sonovation announced on Tuesday that it can insert
ultrasonic biometric sensors under a Gorilla Glass
display, and the device would still be able to read a user's
fingerprints.
Based on Qualcomm's
Fingerprint Sensors technology, the Under
Display Fingerprint scanning feature will generate the
ultrasonic sound waves through the OLED screen.
Ice Universe also said that the new chip will power devices with
ultrasonic fingerprint scanners embedded into the
display.
Besides, Qualcomm has also released its
ultrasonic fingerprint scanning for under -
display fingerprint.
It is not yet mentioned how the technology exactly works but we can get an idea from the Samsung patent where they used 12 pressure point sensors sandwiched between cover glass and
display panel where the scanner passes
ultrasonic signals through an OLED to read the contours of a
fingerprint without making direct contact.
Hence, the
ultrasonic transducers that the acoustic
fingerprint imaging system has could be placed just below a
display, as per Apple Insider.
The sensor, as it turns out, is the latest
ultrasonic fingerprint sensor from Qualcomm that now works through OLED
display stacks up to 1.2 mm thick, up to 0.8 mm of cover glass, or up to 0.65 mm of aluminum (an increase from 0.4 mm for both glass or metal).
The foundation of Vivo's in -
display fingerprint scanner is an optical technology, rather than resistive, capacitive, or even
ultrasonic sound.
The Under
Display Fingerprint Scanning Solution from Vivo works by using piezoelectric effects which will generate and receive ultrasonic sound waves when a finger is pressed against the d
Display Fingerprint Scanning Solution from Vivo works by using piezoelectric effects which will generate and receive
ultrasonic sound waves when a finger is pressed against the
displaydisplay.
It's also interesting to note that a
fingerprint sensor can be spotted on the back panel of these new renders, which contradicts earlier prototype images of a non-curved
display P10, which allegedly houses an
ultrasonic fingerprint scanner just beneath the
display.
