Apple still working on under-display Touch ID, new patent shows

On the other hand, Mark Gurman voiced the opinion that Apple is not so keen on developing under-display TouchID, and is more invested in the FaceID technology. Now, the story has a new twist, as Apple has been granted a new patent.
Here’s an abstract of the description found in the patent documents:
An apparatus for touch-sensing includes a light-emitting layer covered by a transparent layer and configured to illuminate a surface touching the transparent layer and to allow transmission of reflected light rays from the surface to underlying layers. The underlying layers include an optical coupling layer, a collimator layer and a pixelated image sensor. The optical coupling layer bends the reflected light rays to create oblique light rays. The collimator layer includes a number of apertures to collimate the received light rays. The pixelated image sensor senses the collimated oblique light rays.
While the abstract seems like taken from an advanced course in optics or astronomy, what it really means is that Apple is still working on a way to integrate TouchID under iPhone’s display. There were some rumors that the company was actively testing the functionality with iPhone 13 but apparently decided to stick to FaceID with the series.
Another thing that the aforementioned patent reveals is that Apple is going along the optical fingerprint route, rather than experimenting with ultrasonic or other non-light-based technology. Of course, we’re talking about patents here, which means there’s nothing set in stone. Tech companies publish hundreds of patents every year, and only a miniscule percentage of them appear on a mass produced device.
Will there be a TouchID flagship again? - Our take
Even though Apple seems to be lagging behind the competition when it comes to under-display biometry, the question regarding TouchID should be “When”, rather than “If.” The company already brought back TouchID to the latest iPad models, and leaving the iPhone family TouchID-less is not really an option.
Plus, FaceID can only do so much, and there are various problems with it when it comes to users changing their appearance for some reason. Even though Apple says that FaceID is more secure, works faster, and it’s less likely to get spoofed or hacked, the reality is that many online payment services and sites which require authentication in general, now work with fingerprints.
