Finger scanners embedded in the display? Synaptics’ under-glass sensor goes into sampling


It's on, people. The race for eliminating the finger-scanner-in-home-button paradigm, that is. Synaptics, the maker of all things 3D touch-y and biometric-y just announced a new 6x6mm Natural ID FS4500 fingerprint sensor that can be used with hefty cover glass on top.

That's right, the under-glass solution can function underneath a glass or ceramics layer that is as thick as 300um, which makes it a prime candidate for being placed in the type of new capacitive home keys that don't click, like on the HTC 10, or the one rumored for the iPhone 7. As per the Natural ID product page, it can "work underneath cover glass, making it possible to eliminate the home- button cutout. The result? Sleek, edge-to-edge touchscreens with no penetration of moisture or dust." Nice. The new under-glass sensor features include "ability to control two ‘soft keys' with the fingerprint sensor," which sounds a bit murky, but could eventually lead to a complete navigation solutions without the need for huge bottom bezels.

In addition, Synaptics is working towards the goal to incorporate the sensor under the smartphone's protective display cover itself, so in the future handsets might be all-screen down to the lower edge, without pesky chins to get in the way of your screen-to-body ratio, like what is speculated that the iPhone 8 will try to achieve. One Korean competitor has already created such a solution, but Synaptics has the advantage of being the biggest name here, and its under-glass Natural ID FS4500 fingerprint sensor is now sampling with customers, and expected to enter mass production as soon as Q4.

All very exciting stuff. Now they just need to build speakers into the screen and we're all set.

Yes please, under the display is the end game for fingerprint scanners Would mean finally no compromizing between front, back or side Qualcomm was supposedly close, but we haven't seen it working under the display yet

I'd trust Synaptics to make this a reality in the really near future what with their expertize in touch based applications.

No, if the fingerprint malfunction because of the screen. You need to replace the whole screen. I dont like it.

Fingerprint scanner rarely malfunctions. If it does ,you don't need to replace the whole display instead you can easily replace it because it will not be sandwiched between the glass and display. Another advantage is that it will not scratch easily because of tuffer gg present on the whole display. The real dilemma is how Samsung will will use it? After all the home button is so dear to them.

Home button is one of few reason Samsung lead the market. GG quality is bad todays. Screen cracked heavily, does it will works?
