Samsung’s new OLED screen can measure heart rate and blood pressure

Samsung Display demonstrated a new technology that will make smartphone screens more than just image panels. The company introduced the new generation Sensor OLED Display panel, which can measure heartbeat and blood pressure from the fingertip, within the scope of Display Week 2026 held in Los Angeles. The new screen technology aims to monitor basic health data directly on the phone screen without the need for wearable devices such as smart watches or smart rings.

The phone screen turns into a health sensor. The new Sensor OLED Display shown by Samsung is a 6.8-inch panel. The most striking aspect of this panel is the integration of health sensors into the screen. All the user has to do is place their finger on the screen. The panel can measure biometric data such as heartbeat and blood pressure by detecting the interaction of the light emitted from the screen with the blood flow at the fingertip.

This approach is similar to the optical measurement logic used in smart watches and smart rings. However, here the sensor is not on a separate device, but directly inside the phone screen. How does Samsung operate this technology? The new panel combines standard OLED pixels and Organic Photodiodes in the same layer. Organic Photodiodes detect the light reflected back from the fingertip and health measurements can be made based on this data.

The difficult part of this technology is that the screen pixels and sensor pixels have to work in the same area. In other words, the panel must both provide a high-resolution image and be able to precisely read the optical data coming from the fingertip. That’s why it’s important for Samsung Display to reach 500 PPI in the final prototype. There is a 33 percent improvement in resolution compared to the version the company showed last year.

This value is very close to the pixel density we are used to seeing on premium smartphone screens. Therefore, the technology does not appear to be just an experimental demonstration; In theory, it is approaching the level that can be used in a modern flagship phone. It may be remarkable for those who do not use smart watches. Today, when it comes to health monitoring, the first thing that comes to mind is smart watches and wristbands.

However, not everyone wants to carry a device on their wrist all the time. Some users prefer classic watches, while others do not like the limitations of wearable devices in terms of battery, comfort or design. If this technology from Samsung finds its way into consumer products, the phone screen could become an alternative center for basic health monitoring. It can reduce the need for additional devices, especially for rapid heart rate control, blood pressure monitoring or daily health measurements.

Of course, the critical point here will be the level of accuracy. The determining factor will not be whether measurements made from the smartphone screen will replace medical devices, but how reliable the results will be in daily monitoring. Privacy is also considered with Flex Magic Pixel. Samsung Display’s new panel does not only have health measurements. The company also demonstrated its new privacy technology called Flex Magic Pixel.

This system works differently than classical privacy screens. In normal privacy filters, when looking at the screen from the side, the image is completely darkened or severely distorted. Flex Magic Pixel, on the other hand, can only hide sensitive health data. In other words, while other contents on the screen remain visible, heartbeat, blood pressure or similar private information can be hidden from people looking at it from a side angle.

Samsung’s current Privacy Display approach also included the idea of hiding sensitive notifications or certain parts of the screen. Flex Magic Pixel is expected to combine this system with health data more intelligently and selectively. When will we see it on phones? Samsung Display has not announced which consumer device this technology will be used on for now. In other words, there is no clear timetable for when it will come to Galaxy phones.

Despite this, the fact that the panel reached the 500 PPI level shows that the technology is not just a laboratory experiment but is starting to approach real products. This move by Samsung on the screen side indicates that smartphones may take a more active role in health monitoring in the future. In short, you may not need to look at your wrist to check your heartbeat in the future. Simply placing your finger on the phone screen may be sufficient.

Samsung Display introduced its new Sensor OLED Display technology, which can measure heartbeat and blood pressure from the fingertip. The new panel integrates health sensors directly into the phone screen.
