The rapid popularization of smartphones not only allows more people to enjoy a more convenient work and life experience, but also plays an important role in promoting the smartphone industry itself. Today, the smartphone industry has matured, even for low-end models Can also meet people's daily use needs, so users have higher requirements for smart phones, this requirement is mainly reflected in feedback on details, such as the most intuitive appearance design, screen display and other aspects.
Biometrics is one of the important functions of smart phones. Users' requirements for biometrics are mainly reflected in two aspects: recognition speed and recognition accuracy. Corresponding to these two aspects are unlocking speed and security of smart phones. At present, there are mainly two kinds of biometric solutions applied to smart phones, namely fingerprint recognition schemes and face recognition schemes. However, since most smartphones use 2D schemes for face recognition technology, it is difficult to be assured in terms of security. Only Apple High-end flagship models such as the iPhone and Huawei's Mate30 series will use a more secure 3D structured light face recognition solution.
Fingerprint recognition is an unlocking solution that people have become accustomed to, but the location of the fingerprint recognition area is also known as one of the “real” details of smartphone manufacturers and users. Most early smartphones used fingerprint recognition solutions at the front bottom panel. However, due to the popularity of full screens in the later period, the bottom panel of smartphones has become increasingly narrow, and it is not good for the user experience to set the fingerprint recognition area on the front bottom panel. Therefore, most mobile phone manufacturers began to design the fingerprint recognition area on the back.
The design of rear fingerprint recognition has become a mainstream solution for a long time, and it will still be adopted by some low-end models until now, but everyone's usage habits and adaptability are different, and some people adapt quickly And I am used to the rear fingerprint recognition scheme, but some people are more accustomed to the previous fingerprint recognition scheme in the non-full screen era, and if the size of the mobile phone is large, the rear fingerprint recognition scheme is indeed not convenient enough, so mobile phone manufacturers and Suppliers of biometric solutions have begun to develop new fingerprint recognition technologies, which are our common under-screen fingerprint recognition solutions.
However, it is regrettable that due to the screen transparency requirements of the under-screen fingerprint recognition scheme, only OLED screens can use the under-screen fingerprint recognition scheme. Large, but the LCD screen has not been completely abandoned by the market and users, and its "natural eye protection" attribute has also been sought after by a group of users, so some smartphones insist on using LCD screens, such as the latest Redmi K30 series, Honor V30 series, these models have brought another fingerprint recognition scheme-side fingerprint recognition. Although these models were not the earliest to adopt fingerprint recognition scheme, no doubt these models have promoted the side to a certain extent Fingerprint recognition scheme, which can also be seen as a compromise for LCD screens that cannot use the fingerprint recognition scheme under the screen.
Earlier, both Fushi Technology and BOE have revealed that there is a solution for the under-screen fingerprint recognition technology of the LCD screen. Now the LCD screen does implement on-screen fingerprint recognition, but the news was released by the person in charge of the Xiaomi Redmi brand. ——Lu Weibing, Lu Weibing said that the Redmi R & D team has overcome the technical problems of LCD screen fingerprint recognition. At the same time, this solution also has the ability to mass-produce. At the same time, Lu Weibing also revealed the realization principle of LCD screen fingerprint recognition: by using infrared high transparency The film material enhances the light transmittance of the screen, so that the infrared light emitted by the infrared transmitter of the screen fingerprint sensor can penetrate the screen to obtain the user's fingerprint information. The fingerprint is reflected to the fingerprint sensor for feedback verification, thereby realizing the screen of the LCD screen. Under fingerprint recognition.
However, Lu Weibing did not disclose which model will be equipped with this technology first, but netizens speculated that if there is no accident, the upcoming Redmi K30 Pro may be the first to launch this technology.
