MWC Shanghai 2017 Event : VIVO Under-Display Fingerprint Scanner | Full Details

When we think of Fingerprint Scanner on a Smartphone we’ll suddenly see an image in mind of circular ring at the back of the phone or home button which double’s up as fingerprint scanner. But at WMC 2017 Shanghai event, VIVO came up with a whole new concept - the display also acts as a fingerprint scanner How? Let’s Read

What is it ?

VIVO’s under-display fingerprint technology is based on Qualcomm’s Ultrasonic fingerprint sensor. It completely eliminates to place a dedicated scanner on a smartphone by the Manufacture as it has the ability to unlock from underneath the surface of the smartphone. This new technology is supported for surfaces which include OLED screen, metal frame, a specific type of plastic and also ceramic.

How does it work ?

VIVO uses an Ultrasonic sensor underneath the display or rear panel. For unlocking, piezoelectric effects ( the pressure put on the surface) are used to interchange ultrasonic signals which travel through the OLED screen.

When the ultrasonic signals travel through the OLED screen, they create a 3D image of the fingerprint under the Display.

In this video you can see how VIVO is using this technology. Just by placing fingers on the designated area of the screen, the fingerprint is registered and the phone is unlock. See the Video to understand better.

As for the consumers, every time when you need to unlock the phone , not only you have to figure out where to place the finger but also the phones screen-to-body-ratio can be increased.

VIVO suggested the the sensor be implemented behind the metal shell or even in the frame.

What’s the Future ?

This technology is currently a proof of concept and not finalised product.

It is claimed by the company that it will improve waterproofing and anti-ambient light features, further it can also give way for full edge-to-edge display. We can also get to see that the final product can be better than the traditional fingerprint scanners as the this does not use a mirror or a reflective surface which can disturbed by dust, water and even sweat. So using this technology can ensure to have dust-proof, water-proof and sweat proof Fingerprint scanning.
