Tencent Ginx Touch (Gin) Touch ID is a new design introduced by Apple during the iPhone 5s era. By integrating a capacitive fingerprint sensor under the Home button, accurate fingerprint recognition can be used for identity verification such as unlocking and payment. Since then, fingerprint sensors have become a new trend for smartphones, which is of great help in promoting mobile payments and achieving safer mobile applications.

Compared to the optical technology of early business notebooks, the capacitive fingerprint sensor is actually very advanced, with high recognition rate and more secure features, but one disadvantage is that it needs to be designed as a round or rectangular button that is placed on the screen. Below or on the back of the fuselage. Obviously, this doesn't help the phone without a button design.

According to rumors, Apple will launch a newly designed iPhone in 2017. One of the changes will be to cancel the Home button, and Touch ID will be moved to the bottom of the screen to achieve a more compact design. So, how can we achieve this?

Integrate the fingerprint sensor below the screen

Earlier this year, LG Innotek released an advanced fingerprint sensor technology that can be integrated underneath the touch screen for a more compact, more integrated design. LG said that the technology can also support a more flexible fingerprint identification area, and at the same time because of the integration of high-strength glass panels, do not have to worry about key scratches or cell phone water. Obviously, if Apple does not develop its own technology, it is very likely that LG's solution will be adopted.

Ultrasound technology is another option

In addition to integrating the sensor under the glass panel, another "invisible" fingerprint sensor technology is based on ultrasound. In fact, in May of this year, Apple applied for a patent related to ultrasonic fingerprint sensor. This technology uses the core technology of Sonavation. It can identify the user's finger press and fingerprint details through ultrasonic impedance. Ultrasound can pass through metal, glass, OLED, plastic. And other materials.

In addition, ultrasonic fingerprinting technology can pass through a surface with a thickness of 1mm, which means that most mobile phone screen panels are not a problem, and they can also achieve lower power consumption, which is no doubt more helpful for power saving in mobile phones. What is even better is that ultrasonic technology has solved the disadvantages of the current capacitive sensors that are easily dirty and improves the accuracy of identification.

summary

There is no doubt that non-keying is the trend of smart phone design, and fingerprint sensors will not disappear. After all, more and more users have become accustomed to fingerprint unlocking and payment, and invisibility is inevitable. I believe next year, we will see the emergence of mobile phones equipped with a new fingerprint sensor, iPhone is most likely one of the pioneers.
