Although the optical fingerprint under the screen is very beautiful,
new functions such as heart rate recognition have even been developed by the manufacturer. However, the recognition rate is too low when facing stains, which has always been the flaw of the optical fingerprint under the screen. Once the hands are easily contaminated with dust, water and oil stains in the working environment, the sensitivity of fingerprint recognition will be greatly reduced, causing a lot of inconvenience to normal use.
It is precisely
because of this that many users clearly have new machines with more powerful performance and configuration to choose from, but they still prefer their old partners who use capacitive unlocking on their hands. After all, no matter what the environment, capacitive fingerprints can work smoothly, unlocking is fast and sensitive, and there is no need to worry about any foreign objects hindering unlocking.
However, although capacitive fingerprints are powerful,
they are naturally inferior to optical fingerprints under the screen in terms of aesthetics. Either the back must have a circular fingerprint module; or there is a requirement for thickness, otherwise the side fingerprint module cannot be put down. So is there a solution that can have the anti-fouling performance comparable to capacitive fingerprints, and at the same time have the aesthetics of not losing optical fingerprints under the screen? Ultrasonic fingerprints have just stepped onto the stage and become the optimal solution for both.
Ultrasonic fingerprints, as the name suggests, are different from optical fingerprints.
It uses the reflection of ultrasonic waves to recognize the outline of the fingerprint through the screen. In the early years, due to limited technology, the recognition rate of ultrasonic fingerprints was unsatisfactory due to the thickness of the screen and its own hardware algorithm. Although it is not afraid of the interference of wet hands, dust and other stains, the occasional unlocking failure has always been criticized.
However, with the development of multiple generations, ultrasonic fingerprints are now closer to perfection . This year’s Meizu 18 series flagship also gave domestic users a chance to try new things and became the first domestic flagship to dare to eat crabs.
Based on the fingerprint recognition technology of the ultrasonic principle,
Meizu’s Ultrasonic mTouch has an incredible unlocking speed and the applicability of capacitive unlocking. Picking up the phone and tapping to unlock is easy, all in one go, and the speed is no less than other solutions.
And because it uses an ultrasonic fingerprint solution, the Meizu 18 Pro has no pressure when it comes to unlocking with wet hands. Take the phone out of the basin and unlock it directly with wet hands. Such a scene is tantamount to a disaster for the under-screen optical fingerprint unlocking, while the Meizu 18 Pro is easy to unlock without any delay.
Although many domestic manufacturers have tried and launched a variety of prototypes using ultrasonic technology for display earlier,
perhaps because of the recognition rate and other reasons, they all ended up to no avail. The Meizu 18 series undoubtedly introduced fingerprint recognition to the domestic market for the first time, and many users have begun to understand the convenience of ultrasonic fingerprints.
It is compatible with various dirty hand scenes, and there is no shortcoming in the recognition rate now. Meizu even uses ultrasonic fingerprint technology to provide a heart rate detection function similar to optical fingerprints . It can be said that the current ultrasonic fingerprint may be more perfect than other solutions. This time, the popularity of ultrasonic fingerprints in the country may begin with the Meizu 18 series.
