While the introduction of iPhone X's Face ID and facial recognition technology from the Android camp are widely used, unlocking the phone with "Brush Face" is a new way of unlocking that everyone is delighted with, but the hardware supply Business on the "fingerprinting" technology research and development has not stopped because of the widespread application of facial recognition technology.
This year, for the first time in the iPhone X, Apple adopted a "high-screen" shaped screen and Face ID facial recognition technology to replace Touch ID fingerprinting solutions. However, Larger sensor system makes the iPhone X had to leave the "bangs", that iPhone X this very experienced looking at the final cell phone has received mixed reviews.
Why suppliers are interested in research and development under the screen fingerprinting? Under this year's "full screen" trend, the removal of fingerprinting keys or the gradual replacement of fingerprinting by face recognition is a common practice among vendors. So in the "universal screen" a large number of popularization, the best is still under the screen fingerprinting technology, which can be described as the much anticipated a recognition program.
As for the side fingerprint recognition is not why manufacturers are preferred, because it requires the thickness of the phone, which does not meet the current concept of thinner mobile phone design.

Facial recognition security needs to be considered, and the surface of the hole to open the fingerprint recognition is not mobile phone manufacturers to meet the "full screen" trend of long-term good policy.
As early as June of this year, vivo demonstrated the vivo Xplay6 prototype using the fingerprint recognition technology at the Shanghai MWC Conference. Developed by both vivo and Qualcomm Technologies, this technology is identified by ultrasonic waves passing through an ultrasonic sensor under a flexible AMOLED, which gives the fingerprint recognition no fear of surface smudges, liquids, and the like.
However, due to the screen fingerprinting sensor technology still needs to be improved and verified, so vivo this show we only see the hope, but did not see it in volume production this year.

However, hardware vendors do not stop researching on screen fingerprinting.According to Tech Report earlier today, Synaptics (Synopsys International) officially released "the world's first mass production" under the screen fingerprint sensor & mdash; Clear ID FS9500.
According to reports, this sensor using optical production materials and processes, can be directly encapsulated in AMOLED flexible display below or integrated into the OLED screen, the thickness of only 1.5mm. Similarly, it also has the advantages of screen-based fingerprinting solution - no fear of dirt and dirt and so on.

When the FS9500 sensor is activated, the sensor illuminates the fingerprint recognition area through the upper OLED panel backlight, then transmits the reflected optical fiber to the underlying sensor and completes the entire recognition process.

For fingerprinting security, Synaptics said that users' biometrics will be "protected by SentryPoint Security and Anti-Spoofing Kit" technology. And, FD9500 sensor adaptive to the user's habits to enhance the sensor's recognition ability and unlock success rate.
Tech Report speculationSynaptics will be unveiling the technology at the earliest CES 2018 in early next year, and I believe smartphones using fingerprinting will also be available soon.
