Vivo has equipped the phone with an ultrasonic sensor under the display that reads any physical contact with the display to unlock the device
Vivo took the centre-stage to finally show off the world’s first smartphone with under-display fingerprint sensor at the ongoing Consumer Electronics Show (CES) 2018 in Las Vegas. While Apple and Samsung are said to be still testing this technology, Vivo has become the first company to demo how in-display fingerprint sensing will actually work on its smartphone. The Shenzhen, China-based company said that the phone is now ready to undergo mass production and will start shipping in ‘early 2018’ without revealing the price and other details.
This smartphone, which doesn’t have a name yet, has a full-screen display with the fingerprint sensor below it. The Verge toyed with the device at CES 2018 to test this new technology. It said that the sensor works just like other fingerprint sensors that can register a new fingerprint and unlock the device. However, this technology is slower than the regular fingerprint sensor but this might improve over time, said The Verge.
Synaptics, the company that makes touchscreen technologies, had announced a fingerprint sensor that can be embedded under a smartphone’s display in December. Vivo is said to partner Synaptics to include the latter’s fingerprint sensing technology for this smartphone. As per a report by BGR, Vivo has equipped the phone with an ultrasonic sensor under the display that reads any physical contact with the display to unlock the device. These signals actually create a 3D map of the fingerprint to read and store the data.
In line with the above announcement, a new Vivo X20Plus UD variant was spotted by PhoneRadar on China’s 3C certification website that is said to feature the under-display fingerprint sensor. The UD in the model name Vivo X20Plus UD indicates that there might be an under-display on the smartphone. The listing reveals the smartphone to be carrying a model number BK1124, however, no other details are available. The specifications of this smartphone are said to be similar to the Vivo X20 Plus, which was launched recently.
