First in-screen fingerprint sensor announced in a smartphone

Posted January 14, 2018

The new in-built display fingerprint scanner works just like the conventional fingerprint scanner, but the only difference is that it is built inside the display using Synaptics Optical Sensor.

Instead, it's Chinese firm Vivo which has beaten the likes of Apple and Samsung to the punch, and we got hands-on with its yet-to-be-named smartphone at CES 2018 in Las Vegas.

The showcasing of the world's first in-display fingerprint scanning smartphone (ready for mass-production) marks a significant leap forward in the industry's development, taking users' smartphone experience to a new level.

It works really well, and it's surreal to see the phone read your fingerprint but not actually see any signs of the scanner - just a whole lot of screen.

Fingerprint sensors will still be the first choice for most Android phones in 2018, since other biometric authentication methods available for Android phone-makers can not completely replace fingerprint identification yet. In order for it to work, the finger has to be illuminated, so that the fingerprint scanner can read the reflections of the finger scan.

Once we touch or apply stress on the surface, our fingerprint is registered.

Like many other smartphones, the fingerprint scanner is always waiting to detect a fingerprint when screen is off. "Meanwhile, in-display fingerprint sensors are expected to make breakthrough this year, and vendors like Samsung, LG, OPPO, Vivo, Xiaomi, Huawei are likely to embed this technology, bringing the global fingerprint sensor penetration rate in smartphones to 60%".

Pricing is also now unknown, but the likelihood is that this will be an expensive handset. Vivo In-Display Fingerprint Scanning Technology replaces the physical fingerprint button on the screen, laying the foundation for a truly immersive experience. We can also expect some new flagship phones with under-the-display from other companies in 2018. However, the technology is still a few years out. The screen would register the fingerprint digit, spinning up a spider web of the blue pattern. "It will be realized more subtly under the screen, behind the metal shell, or even in the frame", Vivo told Engadget in an exclusive interview on the sidelines of MWC, Shanghai.
