"On December 5, on the first day of the annual Qualcomm snapdragon Technology Summit held in Hawaii, Qualcomm announced the world's first commercial solution supporting off-screen ultrasonic fingerprint: Qualcomm 3D acoustic sensor while displaying the next-generation mobile flagship chip snapdragon 855.
According to Qualcomm, its own 3D acoustic sensor is the only mobile solution that can penetrate different types of stains and accurately identify fingerprints. In addition, this scheme supports slim and avant-garde product design, with higher safety and accuracy.
At present, most of the smart phones with screen fingerprints we see on the market use screen optical fingerprints. The feature of this technology is to use the light emitted by the sensor under the screen to read the fingerprints on the screen, which has high requirements for the lens of the sensor in order to ensure the amount of light. However, optical fingerprints also have obvious defects. If there are stains on the screen or water on the hand, reading fingerprints is not so accurate, which also affects the recognition speed.
Qualcomm's 3D acoustic ultrasonic fingerprint scheme uses microseismic sensors for ultrasonic detection to accurately scan the unique 3D features of fingerprints, so as to obtain the same biometric authentication experience as traditional fingerprint identification. Ultrasonic fingerprint is considered to be a more accurate fingerprint reading scheme than optical fingerprint, which can accurately scan the gullies on the fingerprint surface and the underlying tissue, and ultrasonic technology is very little affected when there is dirt or residue on the finger.
According to Qualcomm's introduction, compared with the traditional 2D fingerprint identification, ultrasonic technology can identify the fingerprint more stereoscopically, that is, commonly known as 3D scanning. The detectable area is larger, and has higher accuracy and better security performance. It can't be deceived by a fine fingerprint plane alone. The key is that it can work even when there is a small amount of dirt or moisture on the user's fingers, and even penetrate some obstacles such as glass, aluminum materials and plastics for identification.
As for how thick glass or metal Qualcomm's latest 3D ultrasound can penetrate, there is no detailed introduction at the summit. Maybe technically, Qualcomm does not want to apply it in this regard. However, Qualcomm confirmed that its 3D ultrasonic scheme can not only handle the fingerprint identification applications of wet hands, oil screens and dirt screens, but also be used for directional gesture detection, underwater fingerprint matching and device wake-up, and even detect heartbeat and blood flow.
Gao Tong said that Qualcomm 3D on-screen ultrasonic fingerprint solution can support more slim and avant-garde shape design, advanced functions, unique mobile authentication experience and enhanced security authentication, making it easier for operators and OEMs to realize product differentiation, so as to achieve more design flexibility. At the same time, the solution can be used as an integrated solution for Qualcomm Xiaolong mobile platform or as an independent sensor for other non Xiaolong platforms.
Qualcomm also confirmed that the newly released Xiaolong 855 chip fully supports Qualcomm 3D on-screen ultrasonic fingerprint solution, but whether this technology will come out depends on the mobile phone manufacturer. It is reported that Samsung's Galaxy S10 early next year will be the first mobile phone to provide 3D under screen ultrasonic fingerprint identification technology. When other manufacturers will provide it is unknown.
In any case, ultrasonic fingerprint technology seems to be a better choice than optical screen fingerprint at this stage, because it means that in the future, the sensor does not have to be on the surface of the mobile phone, does not need capacitive sensors or buttons, and does not need various touch controls. It can be completely hidden under any part of the fuselage, such as glass, plastic or even metal, For example, put it on the mobile phone screen, frame, etc., so as to further improve the screen share.
The world's first 5g commercial snapdragon 855 processor is also the third chip with 7Nm process in the smartphone industry. Battery life, video, games and XR (the extended reality concept proposed by Qualcomm) have been improved.
It is worth mentioning that Xiaolong 855 processor does not adopt the current mainstream independent NPU design, but still uses the CPU + GPU + DSP scheme of Xiaolong 845. You should know that when the first two 7Nm mobile phone chips were released, NPU became the "highlight" -- Huawei's Kirin 980 chip added two independent npus to take charge of artificial intelligence; While Apple A12 reduced the size of CPU and GPU cores, the area of NPU increased from 1.83mm of a11 ² 3.16x to 5.79mm ²。
For the "maverick" Xiaolong 855, there is no independent NPU. How to ensure higher and higher AI capability and first-class performance?
