Apple patent filing for under-display biometrics capture system published

A new method for capturing face, fingerprint and iris biometrics from under the display of an electronic device is the subject of a patent application from Apple newly published by the U.S. Patent and Trademark Office.

The published patent application, spotted by Patently Apple, describes the use of infrared sensors, possibly quantum film infrared sensors, to capture various user biometrics, and possible hand gestures.

Quantum film is a kind of thin semiconductor film, made up of colloidal quantum dots, mechanically and electronically bound together, which absorbs light, according to the filing for ‘Electronic Devices Having Quantum Film Infrared Sectors.’ Light sources and photodetectors could be built into the film, emitting and sensing infrared light through the display surface.

Proximity sensing and distance measurement could be used to capture two- or three-dimensional images of objects and their features, with fingerprints, faces and gestures all noted as examples.

The latest rumors have Apple waiting until at least 2025 to implement under-display biometrics, with Face ID continuing to operate from a notch cut out of the display area until then.

As always with patents, it is worth bearing in mind that even the inventions of companies that exist to make things, rather than simply sue other organizations, may never be used in the development of a commercial product.
