Most of today’s smartphones have an ultrasonic fingerprint sensor built in under the display. Samsung, one of the pioneers of this technology, is introducing an advanced panel for future devices that can read fingerprints on any area of the screen and measure health data such as blood pressure.
- Samsung presented a new screen technology at the SID Display Week
- The new panel is called a sensor OLED display
- It can recognize fingerprints on any area of the screen
- The SOD features biometric sensors that can measure the user’s blood pressure and heart rate
Samsung presents a new display technology
At the SID Display Week in Los Angeles, Samsung introduced the new display called Sensor OLED Display (SOD), which drastically improves fingerprint recognition and biometrics in smartphones and tablets. It has an embedded light-sensitive organic photodiode (OPD) that is not built in separately compared to current solutions.
The use of the OPD allows fingerprints to be scanned on the entire screen, instead of only using part or the lower area, as is currently the case with the Samsung Galaxy S23 (test) and Galaxy S23 Ultra. It also improves security by allowing multiple IDs or fingerprints to be entered during authentication.
This is how the new technology works
However, the most notable feature of the sensor OLED display is the support for biometric data. According to Samsung, the panel uses the OLED light to monitor the user’s health or biometric data.
In concrete terms, the light is radiated onto the blood vessels of the user’s fingers when the user presses on the display. Blood pressure and heart rate are determined based on the variation in reflected and refracted light falling back onto the display. The method is somewhat similar to how the 3-in-1 bioactive sensor on the Samsung Galaxy Watch 5 Pro we tested works, which uses a spectrum of light and lasers.
It’s currently unclear when we can expect the technology on a Samsung smartphone or tablet. But considering it was already demoed at Samsung’s display conference, we could probably expect it soon.
What do you think of the possibility of a Samsung smartphone featuring on-screen biometric recognition? Is this an important feature you would consider in the future?We would greatly appreciate it if you could share your answers in the comments section, using the English language.
