Screen fingerprinting is the future? Mobile phone manufacturers focus on R&D screen fingerprints

At present, the identification method of fire on the market should be faceID and screen fingerprint technology. "Face recognition and the fingerprint of the screen are the future" On this topic, a discussion was initiated in the circle of friends. Some people think that the screen fingerprinting system is more mature and has a huge space for development. However, some people think that the birth of FaceID is a surprise, and at the same time, how the technology that Apple pushes will not die immediately.

The full-screen trend has swept the way of unlocking positive fingerprints in the past, and has been “abducted” by biometrics such as “facial recognition”. Less than a year, the launch of the vivoX20Plus screen fingerprint version once again broke the rules, regaining a game for fingerprint recognition. Facial recognition and under-screen fingerprinting have become the focus of public opinion inside and outside the industry:

The screen fingerprinting system is more mature and has huge room for development.

I mainly from four viewpoints to demonstrate why screen fingerprinting is the dominant way to unlock in the future.

Viewpoint 1: The screen fingerprint system is more mature and has a huge development space.

In 2017, as the 10th anniversary of the birth of the iPhone, Apple released a big move. The iPhoneX not only uses a comprehensive screen design, but also comes with a dedicated facial recognition function: FaceID, the official said that this is the use of 3D structured light technology, allowing iPhoneX to quickly scan people The face forms 30,000 invisible IRDots on the surface of the face. Just like 3D modeling, the security is up to one million. The birth of FaceID is a surprise, and it has been a long-term plan. Similarly, FaceID came out. As you step into the bottleneck of development, it's hard to imagine what else can be or is worth improving in addition to the “unlock speed”.

Different fingerprint recognition, light recognition is divided into four types: optical recognition, capacitance recognition, thermal identification and ultrasonic recognition. Capacitive modules with "lightweight and low cost" are the mainstream solutions for most smart phones. At present, the saturation of the market has reached a peak, which has prompted major manufacturers to use more "innovative" solutions. To adapt to the flood of the full screen. Hey, that is to say, four kinds of fingerprint recognition methods, we are only familiar with one of them, and there are three other types that we can familiar with, like four different drinks, we have only had one before.

Four fingerprint schemes

It is worth mentioning that the ultrasonic sensor can be unlocked under the premise of water and oil stains. This way we are full of expectations.

At the same time, the development space is also very large, such as further expanding the unlocking area of ​​the screen fingerprint. Conjecture is not empty talk. As early as 2017, CrucialTec has submitted relevant patents. Its full-screen fingerprint recognition technology (DFS) can identify the user's fingerprints at any position on the screen, compatible with OLED and LCD screens, and is also compatible with optical. Fingerprint identification and current mainstream capacitive fingerprint recognition.

There are rumors that CrucialTec's full-screen fingerprinting technology is likely to be carried on the Samsung Galaxy Note9 released in the second half of 2018, but given the current lack of detailed information, the technical reliability of CrucialTec is still unknown.

In the hands of the vivo, there are two ace cards, "Screen unlocking of ultrasonic sensors" and "Full-screen fingerprint recognition technology". There is no FaceID for development prospects. If you want to fight in the future, I am afraid that it will be like the sky.
