The iPhone X was rumored to have a fingerprint sensor under the display thanks to new screen technology that would allow Apple to increase the screen size of the iPhone by killing top and bottom bezels. It turned out that Apple did remove the home button and nearly the entire top bezel, but it chose not to integrate a Touch ID sensor into the many layers of the iPhone X’s screen.
Samsung wasn’t able to pull it off either, and the first Galaxy device featuring a fingerprint sensor is expected to drop only in the second half of 2018.
But the first smartphone in the world to launch with a fingerprint sensor under the screen is coming soon, and a video shows us a near-final prototype in action.
We already knew that Vivo is the company that partnered with Synaptics to launch the first smartphone in the world with a fingerprint sensor under the display, and CES 2018 confirmed it.
The Vivo phone, sporting an all-screen design is on display at the show, and The Verge was able to test Synaptics’s Clear ID fingerprint sensor.
It turns out the sensor works just as intended both when it comes to registering a new fingerprint and when it comes to unlocking the device. The sensor is slower than a regular standalone sensor, but the technology will only get better:
Clear ID apparently works only with OLED screens, using the gaps between the pixels to scan the fingerprint.
