There are over 2.1 billion smartphones in this world and when you launch a new smartphone, you need to launch with some of the advanced technologies to compete with other smartphones. Thus, you need to come up with new innovations, ideas, implementations. And now that edge-to-edge displays are commonplace on smartphones, the new house for mobile engineering is the creation of the under-display fingerprint sensor. There are over 2.1 billion smartphones in this world and when you launch a new smartphone, you need to launch with some of the advanced technologies to compete with other smartphones. Thus, you need to come up with new innovations, ideas, implementations. And now that edge-to-edge displays are commonplace on smartphones, the new house for mobile engineering is the creation of the under-display fingerprint sensor.
Thus, a new type of fingerprint scanner solution is launched by Vivo which is not under glass, that’s very easy to understand, but this new type of solution is under the thickness of the glass plus display, something nobody has quite mastered on a production sale yet. While Apple and Samsung are racing for some advancement in the field of smartphones to perfect a fingerprint scanner that resides under a smartphone’s display, a Chinese company called Vivo has already done this task and now they’re applauded by all over the world
So, as a result, Vivo recently showcased and launched its new Under Display Fingerprint Scanning Solution at the start of MWC Shanghai 2017 based on Qualcomm’s technology. Vivo alongside launching this fingerprint solution, unveiled its Digital Signal Processing (DSP) Photography Solution targeted for night scene photography and a Hi-Fi audio solution with a customized DAC decoding chip. As of now, no Vivo device with the fingerprint scanning tech is in production, but it will be showing the tech on prototype devices. But what is this about? So, let me tell you about The Vivo Under Display Fingerprint Scanning Solution is based on Qualcomm technology, and the US- based telecommunications giant separately detailed its own display, glass and metal fingerprint scanning solutions at the tradeshow. Qualcomm will be showcasing its own under display fingerprint scanning technology at MWC Shanghai 2017 using Vivo Xplay6. Like Qualcomm Fingerprint Sensor for Display, Vivo’s solution can scan through 1200-micron thick OLED display stacks.
But like every technology has a weak point, it has got its own loopholes. All of these new phones have a drawback: to accommodate the huge screen in the front, the design could not accommodate a physical home button. As a result, the fingerprint scanner, a staple feature of all the flagship phones, needs to move somewhere else, usually to the back of the phone. Also, Apple’s upcoming iPhone 8 is widely rumored to have fingerprint scanner to be embedded directly into the screen. Samsung has tried to use a similar finger print sensor in its Samsung Galaxy S8 Flagship, but could not make it work efficiently in time. Qualcomm’s in-screen fingerprint scanning technology has many drawbacks that would make it quite impossible for manufacturers to employ it in their smartphones. The main issues Qualcomm facing with their technology are about key speed and accuracy. Also, the scanner is not fast and accurate enough for providing a smooth experience to end users. Also, some analysts believe this technology should be made more practical. For instance, this technology cannot work without a thinner cover glass and a flexible OLED panel. So, Qualcomm’s fingerprint scanning solution looks good at paper, for now. But who knows, how it will be practically.
What we can say about this technology is it could turn out to be the most distinguishing feature of Apple’s upcoming iPhone 8. While it doesn’t appear Apple will use Vivo’s solution, Apple is expected to use similar technology in its upcoming iPhone 8. As far as we discuss about Samsung, there are conflicting reports on whether the company will have this feature in Samsung Galaxy S8 or not. Samsung is also working with Synaptics on an under display fingerprint scanner, so it doesn’t look like Samsung would use Vivo’s technology in their smartphones.
Still, after knowing how tough it is to actually make this technology works, it would be really interesting to see other companies using this technology with some piece of positive accuracy. Also, certain points should be kept in mind where Apple would perfect under-the-screen fingerprint technology in time for iPhone 8. If what Qualcomm is showing today is truly state of the art, then it presents an interesting tradeoff for Apple’s next flasgship iPhone 8, offer owners a slow but convenient fingerprint sensor under the display, or give them a fast sensor located on the back of the device which doesn’t look cool? So, it’s all about technology and decisions that they have to make for the betterment of their users.
