In the past few years, fingerprint identification technology has developed rapidly.From the beginning, mobile phone manufacturers placed fingerprint identification modules in the original position below the mobile phone display, to more and more placed them in different positions on the back of the mobile phone, and then put them on the side of the mobile phone.

Now, off screen fingerprint recognition technology enables mobile phone manufacturers to get rid of the constraints of screen size and create truly exciting mobile phones.Fingerprint identification itself is a very cool technology. It reads the fingerprint through the glass of the screen, identifies and scans to determine whether your fingerprint matches the entered fingerprint. Once matched, it will unlock the mobile phone in an instant.

With the popularity of the concept of downloading the full screen of the mobile phone, whether the traditional fingerprint unlocking is unlocked by scraping or pressing on the front or unlocking on the back, it will affect the appearance of the smart device.Fingerprint identification requires fingerprint acquisition window, which is bound to affect the proportion of the screen, so the off screen fingerprint came into being.

Under screen fingerprint identification technology, also known as invisible fingerprint technology, is a new technology to complete the fingerprint identification unlocking process under the screen glass. It mainly uses ultrasonic, optical and other penetration technologies to penetrate various materials, so as to achieve the purpose of fingerprint identification.

The most promising means of this technology is ultrasonic fingerprint identification, which can truly realize the fingerprint unlocking under the screen and directly on the screen. There is no need for back fingerprint sensing notch, front fingerprint sensing device, and even the fingerprint unlocking process can be realized underwater.

What are the advantages of off screen fingerprint identification?

? off screen fingerprint identification can greatly increase the screen proportion. At present, the comprehensive screen publicized by mobile phones, fingerprint smart locks and other devices refers to the design with a screen proportion of more than 80%. In fact, few mobile phones meet the requirements of this proportion. Even if the screen proportion of 80% is only a relatively comprehensive screen, the use of fingerprint identification will still occupy part of the area,Of course, back recognition is a compromise solution, but the operation is anti-human, which also affects the integrated design, and the operation experience is poor, which does not meet the requirements of future industrial design.

? the operation is more hygienic, and the fingerprint identification under the screen does not need to contact the fingerprint module, so there will be no fingerprint trace and residual oil stain.It can greatly reduce the impact of finger dirt, grease and sweat on unlocking, and make fingerprint unlocking more hygienic.

? identification is more stable and adapt to different use environments.Traditional fingerprint identification, due to the influence of oil, dirt, shelter and extreme environment, the fingerprint identification process has deviation and is easy to fail. However, off screen fingerprint identification is expected to solve this problem. Through penetration identification technology, the identification process can be completed even underwater and can be used normally in multiple use scenarios.

How long will it take for the fingerprint identification technology under the intelligent lock screen?Conclusion:

For smart phone devices with off-screen fingerprint identification technology, there are more and more off-screen fingerprints on mobile phones from 2020 to 2021, but mature applications on fingerprint identification smart locks are indeed rare. On the one hand, because the technology is not mature enough and the cost is high, it can only appear on high-end smart locks.All brands are racing against time to seize the highland.This is a good promotion for the technical upgrading of smart home system hardware!
