「ColorOS Know How」In Display Fingerprint Technology

Hello ColorOS SuperFans,

Technology is a never-ending game of innovation. In less than a decade, we've moved from punching PINs to using Face Unlocks an authentication measure on our phones. And just as we were thinking that it couldn't get better, we have a brand new innovation which is taking the tech world by storm: The in-display fingerprint sensor. In-display fingerprint scanners have been a buzzword for quite some time now. After years of rumors and whispers, it's finally launched a few months ago. Hence it begs the question of how is it different from the conventional capacitive sensors and, more importantly, how does it work. So, let's find out -

An in-display fingerprint sensor uses an optical fingerprint sensor to capture the fingerprint data and is embedded under the phone's screen. Few phones 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.

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.

ADVANTAGES OF IN-DISPLAY FINGERPRINT SENSOR :

Magically activating the fingerprint sensor on the phone's screen when needed is a fascinating tech. With many manufacturers opting to shift the fingerprint sensors to the rear of the phone, it raised quite a number of issues. For one, if the phone is lying on your desk then you'd have to pick it up to unlock it. The situation gets worse if the phone is hooked to a car mount. Secondly, with rear fingerprint sensors, you can never be sure that you're hitting the right spot.

Since in-display fingerprint scanners are usually situated at the bottom of the screen, it's easily accessible and more convenient. Other than that, in-display fingerprint sensors claim to work for both dry, wet or cold fingers. Plus, optical sensors are thin and don't contribute much to the thickness of the phone. More importantly, they are fast. In fact, Synaptics's Clear ID claims to match the fingerprints in 0.7 seconds flat. If you were to compare it with Face Unlock, it takes an average of 1.4 seconds to scan a face.

WHAT ARE ITS LIMITATIONS:

As with any new tech, it takes a few iterations to get refined and the same holds true for the in-display fingerprint sensor. It's marginally slower compared to traditional fingerprint scanners. And sometimes, the reader doesn't seem to recognize the registered fingerprints. Meanwhile, the application of any type of tempered glass may most likely give inaccurate results or will cause the sensor to misbehave.

ARE THERE ANY POTENTIAL SECURITY ISSUES:

Since it's an optical sensor and not a capacitive one, it won't be able to sense a pulse, due to which it can be duped with fake scans. Thankfully, the onboard security measures are smart enough to detect spoofed fingerprints.
