When Apple introduced the iPhone X, many assumed that the company will be the first to introduce an embedded fingerprint scanner right underneath the screen – but many were disappointed to learn that it didn’t have the feature when it launched.
Now Vivo is taking up the challenge by introducing a smartphone that has exactly that feature. It’s still a prototype, but it does point to a future where fingerprint sensors placed below the screen is a possibility.
The prototype uses a Synaptics in-display reader. Synaptics introduced the concept earlier last year and mentioned that it will be licensing the sensor to manufacturers and it looks like Vivo is the first one to try it out.
The sensor isn’t visible when the screen is off, but there will be a small animation telling you where you need to swipe your finger. Guests who got to try it out at CES said that the sensor was fast enough and even accurate, but many state it is still not as fast as the dedicated sensors found on other devices.
Synaptics also mentioned that this technology will only work on OLED screen since the sensor uses the spaces under the panel to recognize the fingerprint. On LCDs though the backlight would prevent this from happening.
It might take a while before similar technologies like these appear on more popular brands, that is if they really want a fingerprint sensor placed under the screen.
