The concept of in-display or under display fingerprint was introduced by Vivo when all industry was busy in making 18:9 devices by cutting the bezels they moved the fingerprint sensor to the rear side of the smartphones but it compromises the battery life because space required to put extra hardware in the back side of the device. Vivo introduced its VIvo Apex the first complete bezel-less device with in-display fingerprint and moving camera module. This year OnePlus made it the part of upcoming OnePlus 6T. OnePlus wan’t to launch 5T with in-display fingerprint sensor but it was not able to provide these features at that time. There are couple of devices available in the devices with in-display fingerprint but these are slow, OnePlus said that Oneplus 6t fingerprints sensor unlock speed has no match with other devices.
How it works
In-display fingerprint works by tracing the fingerprint shape and size with the sensors available inside the screen and matching with the authorized prints. Being present under the display it doesn’t create any problem when using wet or dirty fingers. OnePlus claims to store all users fingerprints record safe in Snapdragon’s processor. With regular or consistent usage it will learn more about the fingerprints and allows users to open the device much more faster.
