In-display fingerprint scanners are the norm nowadays and physical buttons seem to be going obsolete in smartphones.
Apple was the first to remove the Home Button on iPhone and replace it with Face ID. But for most phones, fingerprint is still the option.
Samsung is now trying to remove the smartphone fingerprint scanner completely. They first attempted to displace it by re-positioning it from the front of the phone to the back.
A new patent confirms that Samsung has plans to conceal the scanner behind glass. The WIPO published a patent application recently titled Electronic Device Comprising Bio Metric Sensor. The patent was applied for in April this year and it shows a new Samsung Galaxy phone prototype featuring the in- display fingerprint scanner technology.
The patent description reads, “biometric sensor module disposed on the back surface of the display panel“. One of the images seems to be depicting an optical method complete with optical filters and layers. An expensive device like the Samsung Galaxy S10 could be the ideal candidate for it. But a lesser premium upcoming model could also be featuring it.
An optical fingerprint scanner can perform more basic functions than the usual sensors. It can monitor hear-rate and blood pressure with ease. Samsung filing the patent doesn’t necessarily mean the feature is a sure thing but it does suggest the manufacturer is working on something along similar lines for sure.
Rumors about Samsung introducing the in-display fingerprint scanner go a few years back. But nothing concrete ever came out of it.
Other manufacturers that have made the in-display fingerprint scanner a possibility are Vivo and Oppo.
The Vivo V11 has an in-display fingerprint scanner, the company’s trademark. It’s similar to the one on the Vivo Nex. It’s slightly slower than a traditional fingerprint scanner, but still more convenient to use than a scanner on the rear of the phone.
It has an aspect ratio of 19.5:9 and comes with what is being named as Halo FullView Display by the company, a 6.41-inch Super AMOLED screen. Since the in-display fingerprint technology only works with AMOLED screens, it definitely represents an upgrade for the V series.
