Samsung unveils OLED display with built-in sensor capable of measuring heart rate with a single touch

Samsung has announced its latest display innovations, including new OLED panels with higher brightness levels, a wider color gamut and an integrated biometric sensor capable of measuring heart rate directly through the screen.

The South Korean company is taking part in Display Week 2026, held in Los Ángeles from May 5 to 7, where it is presenting its latest developments under the slogan “The Spectrum of AI Display Innovation.”

Among the most notable announcements is ‘Flex Chroma Pixel’, an OLED technology designed for smartphones capable of reaching peak brightness levels of 3,000 nits while supporting 96% of the BT.2020 color space, delivering a color range approximately 1.7 times wider than the DCI-P3 standard.

To achieve this performance, Samsung Display — the division responsible for display development — implemented a phosphorescent sensitized fluorescence technique to improve color purity and reproduction in OLED panels. The company also incorporated its proprietary LEAD technology, which combines low power consumption, high brightness and a polarizer-free structure.

As for the ‘Sensor OLED Display’, it is an OLED panel with an integrated biometric sensor capable of detecting blood flow using the light emitted by the display itself. This allows users to measure both heart rate and blood pressure simply by touching the screen.

Samsung showcased this technology on a 6.8-inch panel that combines RGB pixels and organic photodiodes through a co-deposition process. This method maintains high image quality without sacrificing resolution, achieving a density of 500 pixels per inch (PPI).

The ‘Sensor OLED Display’ also includes the privacy technology ‘Flex Magic Pixel’, designed to conceal sensitive information when viewed from the side, unlike traditional approaches that completely block side visibility.

EL-QD displays

Alongside these OLED innovations, Samsung Display also introduced its new EL-QD electroluminescent quantum dot displays, which deliver 25% higher brightness compared to the models showcased last year, reaching 500 nits on an 18-inch panel.

This technology uses quantum dot pixels capable of emitting light directly through electrical signals without relying on OLED technology, enabling high color accuracy and improved energy efficiency.

Stretchable Display 2.0

Samsung also brought an updated version of its stretchable display for vehicles to Display Week 2026, based on micro LED technology and offering higher resolution by increasing pixel density within the bridge structure.

According to the company, this technology is expected to dynamically adapt the display to driving conditions and maximize the visibility of information shown to drivers.
