Samsung Display said on the 20th it will begin full-scale supply of tandem OLEDs for notebooks to global PC makers that meet the International Display Metrology Association (VESA)'s new high-brightness certification tier, "DisplayHDR True Black 1400."
True Black 1400 is a certification standard VESA released this month. To be certified, a screen must render black very deeply, nearly perfectly, while achieving a peak luminance of 1,400 nits for full-screen brightness. The brightness requirement is 40% higher than True Black 1000, the previous top tier. Products that earn this grade pair OLED's characteristic deep blacks with an even brighter screen.
The tandem OLED for notebooks that Samsung Display is supplying this time can deliver up to 1,600 nits of brightness at the panel level. That is more than 40% higher than the 1,100-nit peak brightness of conventional OLEDs (a structure with a single emissive layer), and it is considered the brightest among notebook OLEDs currently available.
Lenovo's "Yoga Pro 9i Aura Edition 11th generation (16-inch)" equipped with this panel obtained True Black 1400 certification on the 8th. From the second half of this year into next year, major customers including Asus, Dell Technologies, and MSI also plan to roll out, in sequence, True Black 1400-supported products featuring Samsung Display panels.
This panel features a tandem structure that stacks two organic emissive layers that emit light, achieving both brightness and lifespan. Because the two emissive layers emit light together, it can be made brighter with the same power; conversely, when producing the same brightness, the load on each emissive layer is reduced, extending longevity. In practice, at typical notebook usage brightness, the lifespan of tandem OLEDs is more than twice that of conventional OLEDs.
New organic materials newly applied by Samsung Display are also cited as a driver of the performance gains. In OLEDs, brightness and lifespan vary with the efficiency and stability of the light-emitting organic materials, and the company noted that adopting new materials improved both.
Samsung Display will exhibit the panel at K-Display 2026 Korea Display Industry Exhibition, held at COEX in Seoul from Aug. 22 to 24. It will be featured in the booth's top-performance showcase zone, with video tailored to usage environments that require precise image quality checks, such as video editing and content review.
Jung Yong-uk, head of Samsung Display's IT Strategy and Marketing Team (executive director), said, "High-performance notebook OLEDs that meet the True Black 1400 standard are flagship products that prove Samsung Display's advanced materials technology," adding, "We will continue to expand our high-performance OLED lineup to deliver differentiated product experiences in the premium notebook market."
