This latest fingerprint scanning technology delivers a whole new mobile experience by enabling users to unlock their smartphone through one-touch fingerprint scanning directly on the smartphone display, while solving the industry's challenge of providing a better and more convenient fingerprint authentication experience in future smartphones. According to vivo, the in-screen fingerprint sensor will be available on a ready-to-produce smartphone soon. Under display fingerprint sensor is a technology that has been long expected to arrive as smartphone manufactures bring out edge-to-edge displays.
With the move to edge-to-edge screens and narrower bezels, there's just no room to put a fingerprint sensor on the front of a phone anymore.
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.
By far the most buzzworthy new smartphone unveiled at CES 2018 earlier this week, Vivo's in-display fingerprint-recognizing prototype sure looks familiar. To create this reflection, part of the screen has to light up, and then the finger reader will capture the reflection between the AMOLED pixels. However, the sensor wasn't as responsive as Vivo would have liked. Now smartphone manufacturers can use a fingerprint sensor on the front of the phone, without compromising on the thin bezels or the size of the phone.
Registering your fingerprint works the same way it does on a phone with a regular fingerprint sensor. This is an awkward location of the fingerprint sensor, leading to many users smudging the rear cameras with their fingers because they mistake it for the fingerprint sensor.
Vivo first showed off its under-screen fingerprint technology back in MWC Shanghai 2017. But if you tilt the phone up to activate the "lift to wake" mode, the OLED screen shows an always-on clock and gives you a nice little animation when you press into it. That way, you'll be able to place your fingers anywhere to unlock the phone.
For as many times as the fingerprint sensor worked, it failed just as many times. We played with Samsung's Iris scanner too, that works quite good but it gets confused by a bright sun. It is just a bit slower than what you might be used to from a traditional fingerprint scanner, but not much slower.
That's why I was curious to try out the new Clear ID tech that maker Synpatics has been demonstrating at CES.
