In the early rumors for the upcoming Apple’s iPhone (maybe iPhone 8), we got to know that they’re working a fingerprint under display technology which was going to be a revolutionary feature. But just like other what Chinese do, just copied that rumored feature right away, haha.
Coming into the details, at MWC which was held in Shanghai recently, Qualcomm announced their ultrasonic fingerprint feature which actually turns out the fingerprint being under the display. The OLED display needs to be within the thickness of 1.2 mm. The fingerprint recognition also works with dirt, water, and even sweat apart from the capacitive touchscreen. The fingerprint sensor can be actually placed under the display made up of glass (with 800um) or aluminum (with 650 um).
Let’s get apart and say Xiaomi got the Sense ID on its Mi 5s with Qualcomm’s solution to under-display fingerprint sensors. But this time, the officials from Qualcomm gave Vivo a chance to play with the new technology on their Xplay 6. Vivo also launched a commercial for this technology on YouTube. You can watch right over here.
The company also did the same with another smartphone demo unit. But instead on the front, they placed it towards the back of the unit. And to be honest, it works out pretty well. They showed the demo under water and it was right now a hit or a miss thing since it was just a preview and it isn’t perfect yet.
So how does this work actually? If we get under the display, we’ll be able to see a chip which is actually able to produce some ultrasonic waves. With that said, when the ultrasonic waves bounce off from our finger, they take the fingerprint image in the form of the same waves. And the sensor takes them back in under the display and the phone unlocks. The unlocking actually takes some time but as we know it’s still under development only so no complaints about that.
This “Qualcomm Fingerprint Sensors for Glass and Metal” technology will also work with devices coming with Qualcomm’s Snapdragon 660 and 630 too. As announced by Qualcomm, if people get this technology right into their heads, we’ll be able to see this feature in the devices implementing soon by Q4 of 2017. And if possible, you’ll be able to see the real usage of this technology by the end of Q1 of 2018.
