There's a new home for your phone's fingerprint scanner: inside the screen

However, maybe you prefer fingerprint sensor over even a state-of-the-art face unlocking like Face ID, and you definitely want it in the front because you need to unlock the phone a billion times a day while it's laying on the desk, and you still want a huge display that takes up almost all the room from the front face of the phone. Fingerprint sensor is prone to that and it is not a big secret that placing it under the display makes ideal sense. As the industry moves into a new era of full-screen displays, it is natural that the fingerprint scanning technology needs to evolve to accommodate new user habits and demands for bigger screens without sacrificing user experience. While fingerprint scanner in the rear turns out to be old school, Vivo has come up with the future tech - under-display fingerprint technology.

The best thing about this implementation of a fingerprint scanner is that it looks practically invisible.

This new Vivo smartphone is a prototype at the moment although the companion as said that the handset is ready to go into production. "We are very excited to make it available to consumers soon", he added.

The company now has big automotive aspirations, but more importantly, it managed to be the first company to show us actually working under-display fingerprint sensor.

It supports various usage scenarios beyond unlocking the smartphone, and is only activated when needed.

As you touch the screen, the lit-up fingerprint is then reflected into an in-display fingerprint sensor which is then authenticated. Last month, though, Synaptics, the company behind many of your laptop's trackpads and other input devices, unveiled an in-screen fingerprint sensor called the Clear ID (pictured).

The fingerprint sensor has been made by the sensor company Synaptics, and it has been installed beneath the 6-inch OLED display, and that is the screen that you are actually looking at beneath the cover glass.

Until Vivo officially launched the technology, device manufacturers had to find various alternative methods in order to achieve a bezel-less display on the phone.

Talking about the working, the company uses an ultrasonic sensor underneath the display and follows the principle of piezoelectric effects.

At CES here, a Chinese vendor is showing off a smartphone built with a fingerprint reader that's hidden behind the display. In fact, it's set to be released sometime in early 2018.
