With the launch of vivo NEX and OPPO Find X this year, the full-screen mobile phone with almost all screens on the front has become a new trend. At the same time, the traditional button-type front fingerprint recognition in the flagship machine has gradually been replaced by screen fingerprint or 3D face recognition.
The Xiaomi 8 transparent exploration version released at the end of May this year even adopted two biometric recognition technologies: screen fingerprint and 3D face recognition. The rumored Huawei's new flagship Mate 10 series will also support off-screen fingerprinting and 3D face recognition technology. However, as Huawei, which has just been promoted to the world's second-largest smartphone maker, it may not choose the same technical route as Xiaomi or OPPO and vivo.
The design of the rear fingerprint used on Huawei's previous generation Mate 10 Pro, although the Mate RS version is also equipped with rear fingerprint recognition, but it also uses optical under-screen fingerprint technology. At present, Xiaomi 8 transparent exploration version, vivo NEX's screen fingerprints are based on optical technology.
However, Huawei's new generation of flagship Mate 20 series may use Qualcomm's second-generation ultra-wave fingerprinting technology to achieve off-screen fingerprints.
Recently, according to foreign media BGR broke, the Huawei Mate 20 Pro will apply Qualcomm's second-generation ultrasonic fingerprint technology.
Prior to this, Core Intelligence has introduced Qualcomm's second generation ultra-wave wave fingerprint recognition technology. It has the characteristics of waterproof, oil discharge and living body detection. It can penetrate 800μm glass and 525μm metal in penetration, and can also penetrate 1300μm OLED screen. At present, the thickness of the flexible AMOLED screen can be reduced to 100-200 μm, and the glass cover can be about 500 μm, so that fingerprint recognition can be realized within the screen display range.
It is reported that the advantage of this technology is that it can work accurately even under the thickness of 800 microns, while the traditional fingerprint technology can only be accurate to 300 microns.
Previously, the glory 10 that has been released is the Qualcomm ultrasonic fingerprint recognition technology, but its position is on the bottom border of the screen, not under the screen. It is worth mentioning that there is news that Samsung's next-generation S-series flagship may also be equipped with Qualcomm's second-generation ultrasonic fingerprint technology.
Therefore, the Huawei Mate 20 series, which will be released in October this year, may indeed adopt Qualcomm's second-generation ultrasonic fingerprint recognition technology. In addition, in order to increase the screen ratio, the previous vivo and OPPO have adopted a lifting camera, then if the Huawei Mate 20 series also uses the front 3D structured light, then if you do not continue the previous "Qi Liuhai" or learn What kind of design will the OPPO lift design use? Let us wait and see!
