Apple makes progress in under-the-display Touch ID tech for future iPhones

Till 2022, it was heavily speculated that Apple would introduce new under-the-display Touch ID authentication tech in iPhone and Apple Watch models debuting in 2022-23 because the company had been granted patents for the tech.

However, a report by Ming-Chi Kuo put those rumors to rest. He stated that the under-display Touch ID tech would not launch in the 2023 iPhone 15 as well as in the 2024 iPhone 16.

Now, Yeux1122’s blog claims that the development of the under-display built-in Touch ID has made progress and would debut in iPhones after 2 to 3 years.

Apple might add oxygen and pulse rate measuring features in future all-screen iPhones

The report details that the tech company would replace the punch-hole notch with under-the-display Touch ID sensors in the coming years on all-screen iPhones without a notch.

New system that combines short wave infrared + optical system, etc. 12 related patents have already been obtained​

In order to implement these functions and improve recognition speed, parts containing single-element sensors (eg photodiodes, phototransistors, photosensitive elements, etc.) and multi-element sensors (eg complementary metal oxide semiconductor arrays, photodiode arrays) are required. Applied.


The new Touch ID sensors would be used for quick authentication and more importantly, to offer advanced features to measure oxygen saturation and pulse rate. 

For example, what is different from existing fingerprint recognition sensors and solutions is that it is possible to identify the user’s vein pattern,

It is possible to measure the user’s blood oxygen saturation and pulse rate.​

It also shows fast situational recognition rate by determining whether the user is wearing gloves and whether the user’s fingers are wet or dry.

Currently, Apple Watch Series 6 and later feature the Blood Oxygen app to measure blood oxygen levels, and all Apple Watch models feature the Heart rate app to measure the number of times your heart beats per minute.
