- A Chinese smartphone manufacturer, Vivo, made a smartphone that, for the first time, uses a fingerprint scanner that works from underneath the display.
- This eliminates the need for front bezels, and avoids compromises such as putting the sensor on the back.
- Some companies, however — namely Apple — have moved to other forms of biometric recognition, so it’s unclear whether 2018 flagships will focus more on that or follow Vivo’s lead instead.
Fingerprint readers that hide underneath the display have long been rumoured and talked about, and today, Chinese smartphone maker Vivo is actually making that a reality.
At CES 2018, the company unveiled a production-ready (but, as of yet, unnamed) smartphone that has both a near-borderless display as well as a fingerprint reader, but the scanner itself is nowhere to be seen.
That’s because, for the first time in a finalized product, the scanner is hidden behind the display, at the bottom, and it uses a sensor from technology firm Synaptics to authenticate a user’s unique fingerprint by peering through the gaps in between the screen’s pixels.
The biometric identification tech itself isn’t new, and neither is the concept; Qualcomm has showcased a number of prototypes over the last few years, and its own ultrasonic reader (which aims to achieve the same purpose as Synaptics’) is said to make its way to actual devices in 2018.
Synaptics’ reader, however, is not ultrasonic, but optical: The so-called Clear ID is actually a small sensor that sits right beneath the device’s organic light-emitting diode (OLED) display, and can recognize a fingerprint by scanning the space in between each individual pixel.
It’s important to note that the display technology is OLED; OLED panels, in fact, have those light-emitting diodes that light up individually, and therefore don’t require the presence Read More Here
