Apple could be working on an infrared in-display fingerprint scanner

Apple received a patent for an image sensor located under the display by the US Patent and Trademark Office. The patent that was filed in October 2018 suggests that the company may be planning to add a fingerprint scanning technology. on screen in your future offerings. In the past, Apple used a physical fingerprint scanner called Touch ID and then moved to Face ID with its iPhone X series. According to the patent, the input sensor will be placed between the ‘outer protective cover’ and the ‘battery of display’.

the patent archived by Apple with the US Patent and Trademark Office with patent number 10,824,837 B2 as of October 2018 has already been granted. It includes plans for an “optical imaging sensor” that is “positioned at least partially behind a screen and configured to emit short-wave infrared light.”

It should be noted that patents often indicate avenues that a company may be exploring. Proprietary research doesn’t always have to translate into mass production. Apple’s patent suggests that it plans to introduce an in-display fingerprint scanner with one device, however it is currently unclear if it could be for the next-gen iPhone and iPad models, if at all.

The Apple patent includes a protective outer covering that will be the interface surface, a screen placed next to the protective outer covering, and an optical imaging system that comprises a light emitting element that produces short-wave infrared light. This is basically how an in-display fingerprint scanner works, as the light reflected from the finger is used to build a unique image or fingerprint. Another method of on-screen fingerprint authentication is “ultrasonic,” which involves sending ultrasonic pulses to detect the peaks and valleys of a fingerprint. It is present in the Samsung Galaxy S20 phone series.

In the past, Apple has steered clear of in-display fingerprint scanning. After his Touch ID system, which was last seen on iPhone SE (2020), switched to Face ID starting with iPhone X Serie. Apple has also decided to stick with Face ID for its latest iPhone 12 series, but decided to go with Touch ID for its new Ipad air.
