An in-display fingerprint sensor was a trending topic in 2017 with the age of bezel-less smartphones upon us. People were wondering when they’d get rid of stretching their index finger all the way to the back of the phone to unlock their device. Whereas for some Sony devices that power button on the side of the phone could be used as a fingerprint sensor as well. While most people expected Samsung or Apple to come up with the in-display fingerprint sensor, it was actually Vivo to start the trend.

Vivo on Tuesday announced that it had its first smartphone ready with the in-display fingerprint sensor. This was possible due to the new Synaptics optical sensor, which was said to be under development for years. When you place your finger on the display, the sensor turns on the display to light up the area of your finger after which it reads it and unlocks your phone. It is slower as compared to the traditional fingerprint sensors but not that slow. There is a possibility that this is the same tech that Samsung and Synaptics were collaborating on last year for the S8 until it became clear that they didn’t have enough time to pull it off. It only works on phones with OLED displays as they do not require a backlight.
This new tech by Synaptics is known as Clear ID. It’s like a home button you can use to unlock your phone which just disappears after you’re on the home screen. It’ll be interesting to see who will be the next one to release a smartphone with the in-display fingerprint sensor.
