Qualcomm’s under-display fingerprint sensors coming in 2018

Qualcomm has announced the next-generation of ultrasonic fingerprint sensors, which will allow manufacturers to place their fingerprint sensors under the front display of a phone (pretty much what Samsung had initially planned for the Galaxy S8, as well as rumours that Apple may try something similar for the next iPhone).

Qualcomm Fingerprint Sensors can also be used under metal and glass on the rear of a phone. The sensors can cope well with water well too, being able to wake the phone underwater. Their versatility doesn’t stop there though, as the sensors have health uses, being used to detect heart rate and blood flow.

If you are wondering how these fingerprint scanners work, well, the ultrasonic sensor uses sound waves to penetrate the glass or metal to work out the pattern of your finger. However, the main limitation is the thickness of the material used. The Qualcomm Fingerprint Sensor for Display can scan through OLED display stacks of up to 1200um, while the Qualcomm Fingerprint Sensors for Glass and Metal can scan through up to 800 µm of glass and 650 µm of aluminium.

The first devices with these under-surface fingerprint sensors are expected to arrive during the first half of 2018. We would expect this to be one of the big points of differentiation in premium smartphones next year.

The under-display sensor is designed for use with OLED displays, so it’s unknown if Sony plans to adopt this for its 2018 devices. Sony has traditionally used LCD displays for its Xperia smartphones, although we have heard various rumours that the company may produce an OLED-equipped Xperia device next year.

Vivo is currently demoing the new fingerprint sensor at Mobile World Congress Shanghai 2017, using modified versions of the VIVO XPlay 6. Check out a short promo video below highlighting how it works below.

  • The last in line with the tucked-under-glass feats will be to have a camera seamlessly placed under the screen.

    No idea how that’ll be pulled off, but waiting for that.

    When that happens, then we can have a true all-round edge-to-edge displays.

  • This tech was first mentioned a few years ago. Wasn’t it supposed to debut on the Z4 or Z5?

  • How would one hold a phone then, if it’s a true edge-to-edge display?

    What’s the fascination that people have in getting rid of bezels, anyway?

  • Emil Oskarsson

    Getting rid of bezels makes the phone look great, but it also makes it hard and uncomfortable to use in my opinion. Since you barely have any places to nicely rest your thumbs on when watching videos or playing games in landscape mode for example. It also makes the phone more vulnerable, so yeah bezel less mobiles are awesome! Or?

  • Geralt

    Sony Will finally be able to pull edge to edge display on Flagships

  • Chaturanaga Manchanayake

    Okay so Sony should get OLED panels like they did with a1e TV.

    Hi guys…

    The guy from review.ge also posts leaks on forum Esato.
    He has a source that told him, XZ1 Premium might be 100% screen. It would be 6.2″ 4K+ 21:9.
    Also FPS and front cam beneath oled screen.

    Just check review.ge, there is a concept there ( golden color) based on info given by his source.
    He also said 90% of what he posted about XZ1 is right.

  • dragonsneeze

    Isn’t it a little too thin over the sensor? And display also has glass on top, sensor can read through 1200 um. If it only has glass it’s reduced to 800 um? Is it because of the colored glass? I must be misunderstanding this.

  • Khalid Abdi

    Post the whole link because this link isn’t working.

  • SopNaw

    Nice…

  • Battal

    Sony will not adopt this feature until 2025 :)

  • Shubham

    What? Do you even know that Sony’s fingerprint scanner location is on the sides? So, how will it help make display edge to edge? Unless ofcourse they give up stereo speakers.

  • theskig
  • Kadek

    No front camera? I think it’s merely a concept

  • theskig

    I translated the page with google and it says it’s under the display…

    I think it’s pure fantasy.

  • RockStar2005

    F yeah!!!!!!!!!!!! I’ve been waiting for this for a while!!

  • Moisés

    I just read somewhere that with this Sony might be able to use FPS for american devices..

  • Moisés

    XZ1 Premium will have STE Oled

  • Moisés

    Will be under screen too.

  • Geralt

    Side edges, like in XA/XA Ultra/XA1/XA1 Ultra/C5 Ultra

  • ew210

    it’s fake … don’t bother .

  • razorg

    I think it is a fake as well. Rather good fake, but a fake nonetheless :D

  • Does this really matter when Sony already puts the scanner in the best place—on the power button?

  • Ryuzaki Raiga

    Coled

  • Ryuzaki Raiga

    didn’t america version has been disable for power button fingerprint scanner. this can allowed america user to use fingerprint scanner on latest xperia

  • ew210

    how so ?

  • nazia rida
  • Joe Merol

    Some patent dispute in the US. Has been the case for years now.

  • Chaturanaga Manchanayake

    Sad if that happens cause. We won’t be getting daydream and under-display fingerprint sensor. :/

  • And you see, you miss the whole point. Having an edge-to-edge display does not mean you can’t have bezels.

    Have you ever considered you could decide (via software), disable top and bottom of screen to create a ‘bezel’, and turn all screen on whenever you wish to get immersive?

    Just like you can turn on or off on-screen nav buttons, you could just disable close to the edge parts of the screen, should you wanna play a game or so, or if you need the bezels.

    The options to bring back bezels as and when needed, however still enjoy full screen real estate is priceless and much more better than having a fixed bezel 24/7.

    Sony recently showed how the in-screen stereo speaker works in their bravia tvs. With such tech applied to phones, then we can have one giant screen, with everything tucked beneath, able to turn on bezels as and when needed.

    I call it, a Win-Win-Win-Win situation, in all ways!

  • One of the features (not listed in the features) is the bezels. Getting somewhere to firmly hold as I played my FIFA or Asphalt was priceless. I don’t really care about bezels, except…

    When I’m watching movies or videos on the phone (I watched about 95% of movies I would watch on my Z2), I wished that extra bezels were a display.

    You can disable a screen portion to create a improvised bezel, even better, an adjustable one. But with a fixed bezel, it is an encroach you can’t get rid of.

    I’m surprised people don’t see the appeal in edge-to-edge screens. You can get a bezel out of an edge-to-edge, but you can’t get a screen from a fixed bezel.

  • (C):stem

    Having to press the power button to actually unlock your phone does not make the fingerprint scanner location the best.

  • ew210

    obviously you are unaware of the real reason behind disabling a fingerprint sensor on Xperia devices in US …anyway it’s not any patent that is an issue ,that rumor is ridiculous LOL

  • For devices bought in store, yes. But I buy a foreign device on Amazon instead.

  • It is great to see a chinese brand like Vivo is beating other major smartphone brand in this technology. I am looking forward to see how it actually works.

  • perry S

    Totally agree it’s absolutely right under your finger. Perfect.

  • perry S

    Ok so an ‘on screen’ or under screen fingerprint scanner as described in this article – I’d challenge you to pick up your phone and while holding it in one hand unlock it using the onscreen fingerprint scanner and the SAME HAND. IT’d be impossible pretty much.

  • Joe Merol

    You’re so well informed. Why aren’t you saying the real reason then? That is ridiculous.

  • It is possible, but will take a lot more time than when scanner is on the back or, even better, the way Sony did – on the right side (as most people is right handed)..

  • ew210

    Why don’t you spent 20-30 sec of your life too google that ?

  • Joe Merol

    So you don’t know either. Thanks for your important input.

  • ew210
  • Joe Merol

    I guess not, if someone like you managed to find it.

    O meu, dias atrás alguém comentou nos comentários de alguma publicação aqui no XperiaBlog, um site por onde a Sony “ouvia” os clientes e entusiastas, mas agora fui procurar não achei. Tu tá ligado no que to falando?

  • Moisés

    Sim… Deve ser o forum oficial no site deles

  • Ederson Baumbach .*.

    Por acaso tu sabes me informar? Gostaria de participar e de alguma forma poder contribuir.
