Is blood pressure measurement from a screen accurate?

The measurement uses light reflected from the finger captured by organic photodiodes — an established technology in optical sensors. Accuracy compared to traditional cuff-based blood pressure measurement will become clearer through medical validation testing once available in commercial devices.

What's the difference between Flex Magic Pixel and the existing Privacy Display?

The current Privacy Display already has a feature where it can hide only sensitive notifications or a portion of the display. Flex Magic Pixel evolves this to be smarter about specifically protecting health information on screen.

Does this technology replace a smartwatch for health monitoring?

In the long term, embedding health measurements in the screen could reduce the need for a smartwatch for basic functions. However, smartwatches provide continuous 24/7 passive monitoring which cannot be replicated by a press-to-measure screen approach.

Does Samsung Display manufacture screens for other companies too?

Yes, Samsung Display is one of the world's largest display suppliers and manufactures panels for Apple and others in addition to Samsung's own devices.

Will Sensor OLED appear in Galaxy S27 Ultra?

This prototype was shown at Display Week 2026 and its comparison to the Galaxy S26 Ultra architecture — which already ships Privacy Display — suggests a clear development path. Samsung hasn't announced any production timeline yet.

Samsung Unveils OLED Display That Measures Heart Rate and Blood Pressure with Built-in Privacy at Display Week 2026

Samsung Turns the Display Into a Health Monitor — Display Week 2026

The first day of Display Week 2026 sees Samsung Display demonstrate a new OLED display that combines privacy and health tracking features, a display that improves brightness and color rendering, a brighter QD display, and a stretchable display for cars.

Sensor OLED — Health Monitoring Directly from the Screen

The upgraded Sensor OLED Display is a 6.8-inch panel which incorporates biometric sensors that can detect heart rate and blood pressure. This is done by organic photodiodes embedded alongside the regular OLEDs. These photodiodes detect blood flow by seeing light that comes from the display and reflects off the user's finger.

Samsung Display stated: "Sensor OLED Display is structurally challenging to achieve high resolution, as RGB pixels and OPD pixels must be arranged within a single layer. Samsung Display was able to realize 500 PPI resolution through advanced panel design and precise process control technologies."

Compared to last year's version at 374 PPI, the new panel at 500 PPI represents a 33% increase in pixel density in a single year, bringing it in line with the sharpness of OLED panels used in modern flagship smartphones.

Flex Magic Pixel — Smart Health Privacy

A feature called Flex Magic Pixel hides health readings from anyone viewing the screen at an angle, while keeping the display normal for the person holding the phone.

Unlike a regular privacy screen that blacks out completely when viewed from an angle, Flex Magic Pixel only hides the sensitive health information on screen while keeping everything else visible.

Flex Chroma Pixel — 3,000 Nits of Brightness

The Flex Chroma Pixel panel hits 3,000 nits in High Brightness Mode — the highest announced figure for any smartphone-class OLED in HBM mode. For context, the iPhone 17 Pro tops out at 1,600 nits HBM.

It also covers 96% of the BT.2020 color range.

Will We See This in Galaxy S27 Ultra?

Perhaps. The Sensor OLED Display increases pixel density to 500 PPI compared to the 374 PPI of the display introduced last year. No confirmed production timeline has been announced yet.
