Vivo's new cellphone hides the fingerprint scanner beneath the display screen

Vivo's Groundbreaking Fingerprint Sensor is Changing the Smartphone World

Rather, according to that report, which cited comments from a "reputable tech researcher" made on Chinese social media, it will be Vivo (makers of high-end Android smartphones like the Xplay6) who'll be first to publicly demonstrate and lay out plans for implementing the technology. Simply place your finger on the icon and the phone unlocks.If you wake the phone with the power button, then the display will show a lock screen and will unlock the device straight into your home screen.

It also means there's no need for a scanner on the rear of the phone. The technological aspect is just totally invisible and, if you're not paying attention to how challenging this is technically, it feels nearly pedestrian and unimpressive.

As told by the manufacturer, the fingerprint scanner is located between the motherboard and OLED panel.

How soon should we be seeing this integrated to iPhone and Samsung?

"Consumers prefer fingerprint authentication on the front of the phone, and with the industry quickly shifting to bezel-free OLED infinity displays, the natural placement of the fingerprint sensor is in the display itself", Kevin Barber, senior vice president and general manager, Mobile Division, Synaptics said.

Most phones use capacitive sensors for their fingerprint readers, which require your finger to have a pulse to be read.

Vivo's Groundbreaking Fingerprint Sensor is Changing the Smartphone World

Synaptics has said that the sensor takes just 0.7 seconds to recognize and authenticate the fingerprint. While it travels on the surface, it creates a 3D map of the fingerprint under the display.

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.

Vivo this week launched a new smartphone model using a newly announced Synaptics optical sensor, which has been in development for years. 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.

It's one of the longer setup processes though, as it requires three rounds of scanning your fingerprint to build up an accurate image.

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

We'd recommend both thumbs, so it doesn't matter if you're holding the phone with your right or left hand, and both forefingers, allowing you to easily unlock the phone when it's lying on a surface.
