Samsung unveils the world's first fingerprint authentication and ``sensor OLED display'' capable of measuring blood pressure and pulse
Samsung will launch a new generation organic EL (OLED) display that can recognize fingerprints anywhere on the screen and can check the user's heart rate, blood pressure, and stress level by reading multiple fingers at the same time May 23, 2023 - Announced at

In-screen fingerprint sensors on smartphones are usually installed under the display panel as a separate module in most cases, and can only detect fingerprints on a limited area of the screen. The 'sensor OLED display' announced by Samsung this time is said to be able to recognize fingerprints on the entire screen by embedding an organic photodiode (OPD) that senses light in the panel itself.
Being able to recognize fingerprints on the entire screen not only makes fingerprint recognition very easy for users, but also enables `` multi-finger authentication '' that authenticates not only with one finger but also with multiple fingers. , it may be possible to provide users with stronger security.
In addition, the sensor OLED display can measure the user's heart rate, blood pressure and stress level simply by touching it with two fingers. The OLED light reflects differently depending on the contraction or relaxation of the blood vessels inside the finger, and the OPD recognizes the light reflected back from the finger to read health information. that's right. In addition, in order to measure blood pressure accurately, it is necessary to measure the blood pressure of both arms in advance.
Samsung said, 'We have announced the world's first panel technology that can simultaneously sense fingerprints and biometric information.' However, the accuracy and recognition speed of the sensor OLED display, and whether fingerprint authentication and biometric information can be read at the same time have not been clarified.
Apple-related news site MacRumors claims that in early 2023, Apple will receive a patent that will enable TouchID on displays by combining 'short-wave infrared technology' with 'optical imaging systems such as OPD.' I am referring to

It seems that it will be a long time before this patented technology is actually adopted for the iPhone, but as Samsung and Apple proceed with the development, fingerprint authentication and biometric information scanning on the display will be major essential functions in smartphones in the future. There is a good chance that it will be one of the
