As predicted, Vivo showcased fingerprint sensor technology embedded in a smartphone screen on Wednesday at the Mobile World Congress 2017 in Shanghai. The 'Under Display Fingerprint Scanning Solution' is based on Qualcomm technology and was demonstrated running on prototype devices based on the existing Vivo Xplay 6 phone.

Vivo claimed the under-display fingerprint solution, which doesn't require a physical button for the sensor, is "the first to be demonstrated by a smartphone manufacturer". The technology enables the use of a "true full-screen display and an integrated unibody and mechanical waterproofing design", said the company.

"In Vivo's R&D plan, fingerprint scanning will not be carried out by an independent button or region. It will be realised more subtly under the screen, behind the metal shell, or even in the frame.

"Based on ultrasonic technology, the fingerprint recognition technology can be further expanded to realize user interaction, such as gesture recognition, security verification and other fields, which will greatly enhance user experience."
Vivo told Engadget that while the fingerprint scanning function was limited to a small region on the prototype devices, in theory the same sensing technology could be applied across the entire screen, but that it would significantly increase production cost.

Following the unveiling, Qualcomm issued a press release announcing the development of new fingerprint scanners that work through displays, thick glass, and metal, with underwater operation, heartbeat and blood flow detection.
"We are excited to announce Qualcomm Fingerprint Sensors because they can be designed to support sleeker, cutting-edge form factors, unique mobile authentication experiences, and enhanced security authentication," said Seshu Madhavapeddy, vice president, product management, Qualcomm Technologies, Inc. "This provides OEMs and operators with the ability to offer truly distinct, differentiated devices with added value on truly groundbreaking new devices."
Qualcomm claimed the technology was capable of scanning through OLED display stacks "of up to 1200um", and was 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. The company said it had designed the technology as an integrated solution with Qualcomm Snapdragon mobile platforms, and as standalone sensors that can be used with other non-Snapdragon platforms.


Qualcomm said the fingerprint sensors for glass and metal will be available to OEMs this month and should arrive in commercial devices in the first half of 2018. The sensors for displays are expected to be available to OEMs for evaluation in the fourth quarter of 2017.

Apple's upcoming "iPhone 8" is rumored to include a fingerprint-sensing display, but the company has reportedly faced significant challenges in its efforts to develop the technology for its radically redesigned flagship device, due to release in the fall.

Apple is currently in a major legal battle with Qualcomm over its LTE modems, so it seems unlikely the company would consider offering its technology for inclusion in future iPhones. However, the announcement at least demonstrates that the technology is viable, which lends further credence to reports that Apple has perfected its own screen-embedded fingerprint recognition solution. The technology will give Apple's OLED iPhone a significant advantage over its biggest rival, Samsung, which is expected to stick with a rear fingerprint scanner for this year's Galaxy Note 8.

Apple is expected to unveil the iPhone 8 and more traditional "iPhone 7s" and "iPhone 7s Plus" models around the usual September timeframe for iPhone updates, although rumors have suggested supplies of the more expensive OLED handset could be tight for up to several months after the official debut.

It seems rather convenient "unveiling" it now with the disclaimer "it's just a prototype", with the new iPhone (and possibly other Android flagships) coming up later this year.

If you have the technology, manufacture and sell it. I'm sick of OEM's vaporware.

Not quite ready for mass production behind displays, but close:

"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."

Are some of those icons lifted from iOS in these mockups, or are they actually that slavishly copied in this version of Android?
The device is just a mockup and from the looks, it's designed to capture some virality from iPhone 8 rumours! Hoping to get mixed up and promoted through that. Stealing the icons is another step to faking iPhone 8 virality. It was certainly done on purpose!

So it's not impossible, but given the fact that Apple is doing this on their own and that they probably wouldn't use it if it's not completely ready (say slower than current tech) it's still possible it's not coming to the new iPhone.

In my opinion they should delay rather than go with plan B which is putting it on the back. Apple isn't known for rushing anything to market just to be first, but rather for tech that works great.

That statement says to me that the sensors are available to the manufacturers imminently and the "first half of 2018" is their estimation as to how long it would take for the manufacturers to build devices around this and get them to market.
Right, but only for the simpler sensors that work behind plain metal or glass. Such sensors are already available from other suppliers.

What everybody is far more excited about, is the sensor that works behind an OLED display. That's the one which will only be available for OEM evaluation later this year (although it sounds like Vivo already has access).

The difference is why I boldfaced specific words in my post.

some prototypes do make it into a product..

. . . it's still possible it's not coming to the new iPhone . . .
Even though Apple have done nothing to encourage the talk of under screen fingerprint sensing in the next iPhone I still think, given this announcement, that it would be of significant embarrassment to Apple if they did not include this in the next model.

There are a few questions for Apple here though and I suspect there are high level meetings going on about this at the moment.

Do they continue to struggle along to produce their own in house technology to achieve this?

Or, alternatively, do they very quickly kiss and make up with Qualcomm to use these sensors?

Finally, whichever approach they take, are they prepared to delay the release of the new iPhone to perfect this technology?

No matter the route they choose for implementation, I hope the answer to that final question is, "Yes", they will delay.

iPhone 8 (9,10) ...
Hope, the whole screen will be one, big fingerprint sensor!
Any other case (a small square behind the screen) is a sh-i-||y experience!
Peace!

I can't help but think that apple would be "leaking" information about the next iphone to suggest touchID is on the back if that was the case. With the amount of press, rumours and excitement/expectation around the display-integrated touchID I think it would really dull whatever else the iphone 8 has if it doesn't have the integrated touchID.

I may be overthinking this but leaking the fact its on the back would allow people to come to terms with it before the presentation

Gotcha - my apologies.

I missed what what subtly implied by "Glass" versus "Display" in the article.

Remember apple has its own company that makes touchid u derthe display ,so even if apple was in good terms no need for a third party
