Vivo's on-display fingerprint scanner works great


The new in-screen fingerprint sensor technology is also expected to be just as good, or maybe even better than the capacitive fingerprint scanning technology now in use in most Android handsets.

For now, the under-the-display fingerprint sensor works with only OLED displays.

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.

Even though the world's first smartphone with a (virtually) invisible fingerprint scanner might need a few more months before actually reaching store shelves around the world, its most important party trick is already comparable to many commercial solutions in terms of speed.

According to statistics from global consultancy Canalys, smartphone vendors shipped 22 million full-screen smartphones worldwide in the second quarter in 2017, up from 700,000 in the first quarter of this year.

Speaking at the event, Alex Feng, Senior Vice President of Vivo said, "Today's showcase of a ready-to-produce in-display fingerprint scanning smartphone featuring an optical fingerprint sensor is a big leap forward in bringing consumers this long-awaited, futuristic mobile experience". That if true will no doubt make for an exciting proposition. First is the 18:9 aspect ratio, which gave us bigger screens by slimming down the bezels on smartphones, moving the position of the fingerprint scanner to rear and more.

It supports various usage scenarios beyond unlocking the smartphone, and is only activated when needed. Once the fingerprint is registered, unlocking the phone works just fine, like any other physical fingerprint sensors. With Vivo's announcement, in-display fingerprint sensor is now officially here and we expect more companies to use the technology as they look to come with bezel-less displays. You can find out more details about this new technology over at Vivo at the link below. It also enables quick and secured authentication.

Talking about the working, the company uses an ultrasonic sensor underneath the display and follows the principle of piezoelectric effects. In fact, it's set to be released sometime in early 2018.
