Apple’s latest patent reveals an under-display tech for biometrics and gesture control in iPhones and Apple Watch, but we won’t see it on iPhone 15

• Apple’s latest patent shows that sensors under the display can be used for Face and Touch ID, iris recognition and gesture interpretation.
• While Apple has been experimenting with under-display Touch ID for the iPhone, it’s unlikely to feature on high-end models, and it may only return on low-end models like the iPhone SE.

Apple’s latest patent shows under-display sensors that could be used for a variety of purposes, including Face and Touch ID, iris recognition, and even interpreting hand gestures performed in front of the device to power various iPhone applications, Apple Watches and control other devices.

However, display tech expert and analyst Ross Young revealed that Apple’s much-anticipated under-panel Face ID technology may not be implemented until 2025 or later due to sensor-related issues. Despite the challenges, Apple’s engineering teams have explored different approaches to solve the problems and determine the best way to implement the technology.

The patent also describes the use of a quantum well infrared sensor, which could include light sources and quantum well photodetectors, to generate sensor data based on the received infrared light. Additionally, control circuitry could process the data to perform a proximity measurement, capture images of external objects, identify facial features, recognize a user’s gaze direction, track object location, and recognize physical gestures.

Is Touch ID set to make a comeback on the iPhone 15?

Mark Gurman reported that Apple has been experimenting with an under-display version of Touch ID for the iPhone. However, it’s unlikely to be featured in the upcoming iPhone 15 or other high-end models any time soon.

While Apple has been testing an under-display version of Touch ID designed for the iPhone, Gurman suggests there might only be a return on lower-end models like the iPhone SE. However, Apple is not currently considering this option. However, the fourth-gen iPhone SE’s chances of having Touch ID are slimmer as it’s expected to take its design from the iPhone XR, which also has Face ID instead of Touch ID.

The reintroduction of Touch ID on the iPhone in conjunction with Face ID could prove particularly beneficial when Face ID may not be working properly. This dual authentication approach also provides an additional level of security.
