Blood oxygen and pulse measured under the iPhone screen? Apple Touch ID gets a new technology patent

Apple Touch ID has obtained a new technology patent. It is said that it can also measure blood oxygen and pulse? This has led to polarized comments from many Apple mobile phone users. Some said that Apple is worthy of Apple, which has such a high function. There are also children who feel that even the fingerprint unlock has not been arranged, and the blood oxygen and pulse are also measured under the screen, which can be pulled down. It can be seen that everyone is still very controversial. Let's take a look at the specific situation.

Blood oxygen and pulse measured under the iPhone screen? Apple Touch ID gets a new technology patent

According to the latest list published by the United States Trademark and Patent Office (USPTO), Apple has recently obtained a new technology patent for off-screen Touch IDThe "short-wave infrared" technology is highlighted in the patent, and the relevant components are located below the screen or integrated into the screen

This patent mainly introduces the optical imaging system applied to the screen Touch ID. By using the short-wave infrared wave technology, users will generate floodlight when they press their fingers on the screen. The components below the screen can receive and quantify the reflection caused by the floodlight in the short-wave infrared band, and realize the function of fingerprint recognition under the screen.

It is reported that this function can also be used to detect the user's blood oxygen and pulse, judge whether the user wears gloves, and determine whether the user's fingers are wet or dry.

Apple has recently obtained a new technology patent for the off-screen Touch ID, and the "short-wave infrared" technology is the focus. But at present, the development of this function is still in the initial stage. If you want to carry it out, it is estimated that it will be very far away. I hope Apple will arrange the off-screen fingerprint first.
