Everything about the Samsung in-display fingerprint scanner is different and using ultrasonic tech is what makes it different. Prior to the launch of the Samsung Galaxy S10 series , there have been smartphones with in-display fingerprint scanners. However, this is the first time a smartphone features an in-display ultrasonic fingerprint scanner. This is because the ones before it are optical and not ultrasonic. Basically, it uses light to create a 2D image of your fingerprint. On the other ultrasonic type, sound waves is used to make a 3D structure of your finger offering more accuracy.
The ultrasonic scanner used in Samsung’s flagships is actually from Qualcomm, which is part of the added perks of the Qualcomm Snapdragon 855 on board. In fact, this is the third generation of the ultrasonic scanner by Qualcomm. A vision since 2013 when the company acquired Ultra-Scan , a company that produced ultrasonic readers for the US government. The optical fingerprint scanner on the OnePlus 6T , Huawei Mate 20 Pro , Xiaomi Mi 8 Pro and so on is from Synaptics . This way, the Samsung ultrasonic fingerprint stands out from the rest.
How it works
The way it works, the ultrasonic fingerprint world is much more different than the others. The ultrasonic fingerprint scanner sends sound wave which scatters when it hits your finger. This is measured by the scanner, thereby creating a 3D image of your hand. Then stored so that every time you want to unlock your phone it compares the image generated with the one saved. What makes this process more accurate is the ability of the sound waves to penetrate the sub-dermal layer. In this regard it reads into every pore offering much more detail than an optical fingerprint scanner. Unlike the optical scanner that shines light unto your finger thereby capturing only a 2D fingerprint image. If it comes to it, it can be deceived with a perfect printed replica of your fingerprint.

Durability and added perks
Illuminating your fingers through the display leads to a gradual degrading of the OLED screen over time. For this reason, the ultrasonic fingerprint scanner is not only more accurate but also durable. Not to mention the extra potentials of the ultrasonic fingerprint scanner on Samsung’s latest flagships due to its deeper penetration. It could function as a heart rate monitor, read blood sugar and so on. Going back to the primary job here, it can read your fingerprint despite having dirt on your hand.
Physical attributes
You can easily fit an ultrasonic fingerprint scanner into a slim smartphone because of small size. With a thickness of just about 0.2mm which is relatively negligible to the overall 7.8mm thickness of the Samsung Galaxy S10 . In that way, it doesn’t get in the way of the portability of the smartphone. Nonetheless, the ultrasonic fingerprint does not read from more part of the screen as the optical type does. Covering about 25mm x 50.2mm area at the bottom of the Xiaomi Mi 8 Pro and the entire screen on the Vivo Apex 2019 concept phone, the optical reader offers more space. On the other hand, the Samsung ultrasonic fingerprint scanner is active in only part of the bottom screen and is likely not to work with a screen protector.

Conclusion
The Samsung ultrasonic reader pioneers a new system of biometric authentication which is more secure and has more potentials. Upcoming flagships will sure feature this type of fingerprint scanner this year going forward.

Fingerprint readers and sensors have proofed to be one of the best and most secure form of biometric authentication on smartphones out many types of security authentication technology present on modern-day devices. Although nothing beats PINs and passwords, fingerprint scanning feels more natural and comes close in terms of security.
Fingerprint authentication technology was properly introduced on smartphones by Apple a couple of years ago when the Cupertino-based tech giant launched the iPhone 5S. Afterwards, many other OEMs (as always) followed through with Apple’s innovation by placing the regular standalone fingerprint readers either on the rear or front of their smartphones. This continued for years until 2018 … when a particular Chinese smartphone manufacturer saw normal as boring and decided to take the fingerprint reader a notch higher.
In January at the CES 2018 event that held in Nevada, United States, Chinese OEM Vivo unveiled the first smartphone to have its fingerprint sensor embedded in its display. Dubbed the Vivo X20 Plus UD , Vivo beat the likes of Apple and Samsung to the under-display (also called in-display) technology. But how does it work? That, you’d find out below.
How an in-display fingerprint scanner works
An in-display fingerprint is (literally) embedded under a smartphone’s display uses an optical fingerprint sensor (see other types of fingerprint sensors ) to capture and identify users fingerprint information.
This particular type of fingerprint sensor that works under that screen was pioneered by Synaptics, a California-based manufacturer of fingerprint biometrics technology for smartphones and also, touchpads for laptops. Synaptics developed the ‘Synaptics Clear ID sensor’ (named the Clear ID FS9500). The Clear ID is the first-ever optical in-display fingerprint sensor and mass produced it for Vivo to use on the Vivo X20 Plus UD.
Synaptic Clear ID FS9500 optical in-display fingerprint sensor
Now, let’s highlight…
…how the Clear ID works under the display
First off, in-display fingerprint sensors (Clear ID) are produced to work with OLED panels and not on any other smartphone display technologies . This explains why you’d find the in-display fingerprint sensor only on smartphones with OLED display .
Literally, when you place your finger on the device, a light is shone on your finger, the sensor then proceeds to capture your fingerprint and the device is unlock. Technically, in-display fingerprint sensors work by using the light emitted from the gaps between the pixels of the OLED panel. When a hser places a finger on the sensor, this light illuminates the fingerprint and ultimately captures it.
A (very) high resolution image of fingerprint is taken and an algorithm proceeds to detect unique patterns of your prints by thoroughly analyzing every part of the captured image. The algorithm analyzes the dark and light part of your finger, as well as ridges and valleys. To ensure effective capture of your fingerprint data by any in-display sensor, you have to exert a little bit of pressure on the screen so the sensor can accurately differentiate between ridges and valleys of each fingerprints.
Advantages of in-display fingerprint sensor
In-display fingerprint sensors are thin : this makes them attractive as we are entering into an era where manufacturers are looking for the best possible ways to shrink down the thickness of phone sizes. Although many OEMs like Xiaomi and Huawei have now adopted the technology, we expect more manufacturers to get in line.
Easily accessible and Convenient : unlike rear-facing fingerprint sensors that takes some getting used to, in-display sensors are easy to reach and relatively convenient.
Functionality is independent of finger conditions: in-display fingerprint sensors will read your fingerprints accurately even if your fingers are wet, cold, or dry. Fingerprint capture with regular scanners under these conditions are difficult.
SentryPoint Security Suit : In-display sensors comes with industry’s highest level of secure fingerprint authentication.
Shortcomings
As innovative and interesting as the new in-display fingerprint scanning technology is, there are some downsides to it when compared to the regular on-body fingerprint sensor is.
Speed : although an in-display sensor unlocks in about half a second (averagely), it doesn’t compare to the unlock speed of regular fingerprint sensors.
Interference : applying any type of tempered glass may lead to delayed or inaccurate fingerprint capture. The sensor may also misbehave if the tampered glass is thicker than 1.5mm.

Demand for smartphones with edge-to-edge bezel-less displays is rising. That means smartphone vendors have less space for things like fingerprint scanners and home buttons at the front of the phone. For instance, Apple’s iPhone X completely did away with famous home button which also carried a fingerprint scanner used to unlock the device.
However, after several rounds of speculations that the big guns like Apple, Samsung, LG would include in-display fingerprint scanners, it’s Vivo, a major Chinese smartphone brand owned by the same company behind Oppo and OnePlus that has finally made a breakthrough. Vivo announced the Vivo X20 Plus UD, the first smartphone with a fingerprint scanner under the display at this year’s CES. The phone went on sale on January. 24, starting in China as it rolls out worldwide.
The Vivo X20 Plus UD displays a fingerprint icon on the display as soon as you lock the phone. The user then taps on the fingerprint icon on the display to unlock the phone the same way you would with the other phones. It sports a Super AMOLED capacitive touchscreen, 128 GB ROM + 4 GB RAM, Qualcomm Octa-core Snapdragon 660, 12 MP, f/1.8 + 5 MP, autofocus, LED flash camera and runs Android 7.1.1 (Nougat).
We expect more phones to include fingerprint scanner under the display instead of at the front home button or at the back of the phone. The phone will retail for around 3,600 Chinese yuan which about $570.
