of ultrasonic fingerprint solutions with the introduction of «Qualcomm Fingerprint Sensors».
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?
Most recently, Qualcomm announced its next generation
of ultrasonic fingerprint scanners and smartphone manufacturer Vivo demoed the technology in a working prototype handset, which you can see in the GIF above.
Not exact matches
vivo and Qualcomm have built a prototype to showcase the latter's latest
ultrasonic fingerprint scanner, capable
of working through displays and metal backs.
There's also support for Qualcomm Sense ID in a wide range
of chipsets, which support
ultrasonic 3D
fingerprint mapping.
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.
We first presented a prototype
of our
fingerprint scanning solution at MWC Shanghai 2017 based on an
ultrasonic sensor, and have remained committed to realising our vision for future smartphones,» Alex Feng, Senior Vice President
of Vivo, said in a press statement.
Like Qualcomm's, the Vivo Under Display uses
ultrasonic technology, which uses sound waves to capture 3D images
of fingerprints.

of 2016 came with an
ultrasonic fingerprint sensor that is placed under the front panel
of the device.
The latest handset from Chinese smartphone manufacturer Xiaomi stands out as it's the first
of its kind to use an
ultrasonic fingerprint reader.
A 21 megapixel camera and an
ultrasonic fingerprint scanner further add to the repertoire
of the most powerful phone announced so far (theoretically).
At present, Qualcomm has already sent sample
of the under - screen
ultrasonic fingerprint scanning scheme to OPPO and Vivo for test.
Compared with traditional
fingerprint, the advantage
of under - screen
ultrasonic fingerprint is this
fingerprint can achieve
fingerprint scanning on the screen.
In the meantime, the end product that will feature the under - screen
ultrasonic fingerprint Qualcomm has showed before is expected to appear by the end
of this year or in the first half
of 2018.
We first presented a prototype
of our
fingerprint scanning solution at MWC Shanghai 2017 based on an
ultrasonic sensor, and have remained committed to realizing our vision for future smartphones.
Qualcomm has a host
of new technologies in store, including an
ultrasonic fingerprint scanner, cognitive machine learning for your smartphone and tablet, and,
of course, a new processor: the Snapdragon 820.
The new scanner passes
ultrasonic signals through an OLED panel up to 1200 μm thick to read the contours
of a
fingerprint, which obviate the need for a direct touch with the
fingerprint sensor.
Vivo uses the
ultrasonic technology in its sensor that emits
ultrasonic waves that capture a precise image
of a user's
fingerprint to unlock the device.
The Mate 11 supposed to launch in the second half
of the year is rumored to pack Qualcomm's
ultrasonic fingerprint sensing solution.
When Xiaomi unveiled the Mi 5S a few days ago, one things that caught attention
of many technology enthusiasts was its «
ultrasonic»
fingerprint scanner.
To make sure they won't miss out on the rise and prevalence
of either biometric technique, a number
of Chinese smartphone manufacturers are reportedly planning to adopt 3D sensors domestically while pushing screen - embedded
ultrasonic fingerprint scanners internationally.
At MWC 2017, the US - based chipmaker announced the next generation
ultrasonic fingerprint scanners with the introduction of Qualcomm Fingerpri
fingerprint scanners with the introduction
of Qualcomm
FingerprintFingerprint Sensors.
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.
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 devices offer mostly expected updates, including an improved camera and faster processor, but there is one particularly interesting touch — a new
ultrasonic fingerprint reader built under the glass at the bottom
of the phones.
Both variants are rumored by a majority
of tipsters to support
ultrasonic fingerprint recognition and 3D Touch technology, although perhaps you should also be prepared for humbler specs.
The foundation
of Vivo's in - display
fingerprint scanner is an optical technology, rather than resistive, capacitive, or even
ultrasonic sound.
Xiaomi is speculated to be working on Xiaomi Mi 5S, an upgraded
of Mi 5 that will be coming with high - end specs like 3D Touch pressure - sensitive screen, Snapdragon 823,
ultrasonic fingerprint reader, dual camera and more.

of our
fingerprint scanning solution at MWC Shanghai 2017 based on an
ultrasonic sensor, and have remained committed to realizing our vision for future smartphones,» Vivo senior vice president Alex Feng said.
An
ultrasonic fingerprint scanner has apparently been embedded at the back
of the handset.
Finally, as part
of the Snapdragon 820, the phone may use Qualcomm's
ultrasonic fingerprint authentication system.
An
ultrasonic fingerprint scanner works by deploying
ultrasonic waves to recognize a person's
fingerprint, irrespective
of whether the finger is wet, sweaty or covered in filth and grime.
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.
