Ultrasonic under-screen fingerprints will be popular! OPPO OnePlus and other iterative new phones are being tested

According to the latest news from @digitalchatstation, OPPO, OnePlus, and realme iteration flagships are all testing fingerprints under the ultrasonic screen. If everything goes well, they will all replace ultra-thin optical solutions.

He has also previously revealed that Xiaomi Snapdragon 8 Gen4 new flagship is testing domestic single-point ultrasonic fingerprint unlocking.

As we all know, fingerprint unlocking is standard for most mobile phones, and it is also the method that most people prefer to use to unlock their mobile phones. It can be unlocked with a single touch.

But fingerprint unlocking is also divided into categories. Currently, most mobile phones on the market use optical fingerprint recognition technology. Only iQOO12 Pro and Meizu 21/21 Pro are among the few models that use ultrasonic fingerprint technology.

In terms of technological maturity, ultrasonic fingerprints and optical fingerprints are both very mature unlocking technologies at the moment. Optical fingerprint unlocking technology uses the reflection principle of light to form a fingerprint image. Unlocking is achieved by comparing it to a fingerprint template stored in the device.

Ultrasonic fingerprint technology is safer and easier to use. It uses the principle that ultrasonic waves are reflected when they encounter the fingerprint texture. When a finger presses the screen, the sensor under the screen emits ultrasonic waves to the area where the finger is pressed, and then performs comparison and identification. The cost relatively high.

The advantages of ultrasonic fingerprint recognition technology include: strong penetration, strong resistance to water stains and stains, high recognition rate, support for living body detection, and high security.

Editor’s comment:

From the perspective of user experience, ultrasonic fingerprint unlocking is indeed easier to use, both in terms of entry and unlocking speed, than optical fingerprints The unlocking experience is smoother.

If the news is true, then the flagship models in the second half of this year may be equipped with it, making it truly popular.
