In-Display Fingerprint! In-Display Fingerprint! We get to listen this everywhere after the arrival of Vivo V11 Pro they created a hype in the market with the launch, their marketing strategy was this! And Now it’s time for the Oneplus 6T launch and again this time they gonna create the hype through In-Display Fingerprint. But do you how they work? Let’s find out.

The Early Beginning:

Basically, people never thought that this kind of technology or R&D would be done by VIVO   because most of the people believe that miracles can only be brought by SAMSUNG and APPLE. There were many news and rumors that Apple would lighten up the In-Display Fingerprint concept with their iPhone X, but instead of that, they opted for Face ID! And Samsung they postponed it to S10. But the world got shocked when VIVO for the first time tested the In-Display Fingerprint. They lighten up the concept when they launch Vivo X21. It was phone powered by the Snapdragon 660 and comes with 6 GB of RAM and was price around 30-35K the concept was awesome but the fingerprint sucks! I mean it was too slow. But with the time VIVO never gave up as always and launched VIVO NEX which was like a phone of future and was a flagship and was somewhat a success. And then finally a mid-range the VIVO V11 PRO. And Xiaomi is also trying to get their hands on with this technology with the Xiaomi Mi 8.

The VIVO X21 it’s first hands-on during CES 2018

How does it work?

An in-display fingerprint sensor uses an optical fingerprint sensor to capture the fingerprint data and is embedded under the phone’s screen. The Vivo X21 and the Xiaomi Mi 8 use Synaptics’ Clear ID sensor for high-resolution fingerprint scanning. The Clear ID sensor, which is a CMOS chip named Clear ID FS9500, is supported only on OLED and AMOLED displays.

The Vivo X21 uses Synaptics’ Clear ID sensor for high-resolution fingerprint scanning

It works by capturing the reflected light of the fingerprint through the OLED pixels. So, when you touch the phone’s screen, the display lights up to illuminate the fingerprint. The sensor then captures a high-res scan of your fingerprint through the light reflected from the gaps between the pixels.

To ensure that the fingerprint data is being read accurately by the sensor, you’d need to press the screen slightly. This is done so that the sensor is able to differentiate between the ridges and valleys of each fingerprint.

Interestingly, the fingerprint matching is done through Synaptics’ Quantum Matcher software, instead of the in-house Match-In-Sensor technology. Meanwhile, the fingerprint sensor uses the host’s sensors to illuminate the area and activate the scanner.

However, Synaptics’ Clear ID optical sensor is not the only one in the market. In March 2018, Goodix started shipping its informationversion of an optical in-display fingerprint reader. The Huawei Porsche Design Mate RS is the first commercially available phone to feature Goodix’s in-display fingerprint sensor.

This sensor also works in a similar way to the Synaptics’s FS9500 and claims to have a false acceptance rate of 0.002%.

So this was our some information about the In-Display Fingerprint Sensor hope everyone got some knowledge about this technology. And if you have any question, just ask us below in the comment section.
