Samsung Galaxy S10 to use Qualcomm's third-gen ultrasonic fingerprint readers

Peter, 10 September 2018

The Galaxy S10 is expected to be Samsung’s first device with an in-display fingerprint reader (but the Note and Galaxy A series should join it soon after). A report coming out of Taiwan suggests that the company will use Qualcomm’s latest ultrasonic reader for the job.

Qualcomm’s first ultrasonic reader came out in 2015 and there was a sequel unveiled in June last year. A third generation reader has been developed and it finally meets Samsung’s requirements.

But the company will need a huge supply for the initial launch and has reportedly tapped Taiwanese companies General Interface Solutions (GIS) and O-Film to produce the modules. Qualcomm has been working with GIS to develop the new sensor. O-Film has previously worked with vivo to build the X20 UD and X21 UD.

The ultrasonic fingerprint reader will be attached to the back of the display panel. Since optical readers need a transparent screen, Samsung believes they are vulnerable to outside influence (e.g. lighting conditions) and they also impact the image quality of the display.

Plus, ultrasound allows for a 3D image of the fingertip’s ridges and pores to be captured, which makes it more accurate.

However, last months the word from insiders was that only the top two Galaxy S10 models will have an ultrasound reader while the base model will have an in-house optical reader.

Yep, it will drain faster. Difference between an on-screen display and the on-screen fingerprint scanner is that the OSD displays time and notification. While the OSFS uses both the display for the fingerprint scanner and the fingerprint scanner sens...

Makes me wonder... Doesnt an "all the time" onscreen display of fingerprint reader makes the phone drain faster? I think that was the case in the new vivo phone. i hope this one isnt going to be the same.

  • why why

because there is a lack of innovation, they gonna do whatever they can to do something new and get your moneys.
