Vivo shows off an under-display fingerprint scanner based on Qualcomm’s tech

Qualcomm will be showcasing its own under display fingerprint scanning technology at MWC Shanghai 2017 using the Vivo Xplay6


Vivo showcased a prototype smartphone using the Qualcomm’s under display fingerprint scanner announced today.

This prototype was existing Xplay6 with Qualcomm’s under-display fingerprint scanner. So, do not expect any new phone from Vivo with tech soon.

Alongside, Vivo also unveiled its Digital Signal Processing (DSP) Photography Solution targeted for backlighting and night scene photography, and a Hi-Fi audio solution with an customised DAC decoding chip.

For past few months, there were rumors about the possible under-display fingerprint scanner by Apple and Samsung. But, no one expected this tech to come from China.


The technology uses piezoelectrics to send ultrasonic waves through the display glass to read fingerprints. It will even work with wet fingers — so it’ll come in handy with water-resistant tech, too.

According to Richard Lai of Engadget, the fingerprint scanning is a little laggy on the prototype.


According to Qualcomm’s press release, the tech will be available as an integrated solution for Qualcomm Snapdragon, and for non-Snapdragon hardware.

The ultrasonic technology can work through OLED displays, glass, or aluminum, and will arrive in two waves Qualcomm Fingerprint Sensors for Glass and Metal, and Qualcomm Fingerprint Sensors for Display.

Handset makers will get a chance to use the glass and metal-working version this month, but won’t get the display-enabled sensor until the fourth quarter of this year. Phones could ship with the hardware by the first half of 2018.

Vivo claims its under-display fingerprint solution is the first to be “demonstrated by a smartphone manufacturer.”

Coming to Vivo’s other announcement , DSP Photography Solution is designed to help users take pictures with “high quality and accurate exposure, and adjust the brightness of the image to make it better correspond to what is actually seen by the human eye.” It adds that the photography processing speed has also seen a boost.

The Vivo DSP Photography Solution allows smartphones to take multiple RAW images quickly, and can also reduce shot noise for night scene photography to a large extent. The DSP will also improve the beautification effects of Vivo’s Face Beauty Mode.

Come to Vivo’s new Hi-Fi audio solution including new customised DAC decoding chip and headphone amplifier technology.

The new solution improves SNR, dynamic range, distortion, and output power, delivering an SNR of 122dB, dynamic range of 120dB, distortion of -111dB, and output power of 2.2VRms.

The headphone amplifier utilises new processing technology to improve power efficiency as well as the overall audio experience.
