Samsung Display is set to begin supplying tandem organic light-emitting diode (OLED) displays for laptops, achieving a maximum brightness of 1600 nits. The new displays combine OLED's characteristic black representation with high brightness and long lifespan, targeting the premium laptop market.
On July 20, Samsung Display announced that it is supplying tandem OLEDs for laptops that support the new 'DisplayHDR True Black 1400' certification from the Video Electronics Standards Association (VESA) to global PC manufacturers.
True Black 1400 is a new certification from VESA that evaluates both screen brightness and black representation. To qualify, displays must achieve a peak brightness of 1400 nits while maintaining black levels below 0.0005 nits with 10% of the screen pixels active. This standard is 40% higher than the previous top rating of True Black 1000.
The new product from Samsung Display can achieve a maximum brightness of 1600 nits, exceeding the previous maximum brightness of 1100 nits for single-emission layer laptop OLEDs by more than 40%. Samsung Display claims this is among the highest levels for commercially available laptop OLEDs.
The tandem structure, which stacks two organic emission layers, contributes to improved brightness and lifespan. The two layers emit light together, allowing for higher brightness at the same current. When used at the same brightness, the burden on each layer is reduced, extending the panel's lifespan. Under typical laptop brightness conditions, the lifespan is reported to be more than twice that of existing single-emission layer products.
New organic emission materials have also been applied, enhancing the efficiency and stability of the organic materials to increase brightness at the same power level and reduce lifespan degradation due to high-brightness operation.
As competition in laptop OLEDs expands beyond resolution and refresh rates to include brightness and lifespan, the tandem structure is emerging as a differentiating factor for premium products.
Lenovo's 16-inch 'Yoga Pro 9i Aura Edition 11th Gen,' equipped with Samsung Display panels, received True Black 1400 certification on July 8. Asus, Dell Technologies, and MSI are also expected to gradually unveil laptops featuring the new panels from the second half of this year through next year.
Samsung Display plans to showcase the new products at 'K-Display 2026,' which will be held at COEX in Seoul starting July 22. The company aims to demonstrate high-brightness performance, particularly for creators who require precise image quality for video editing and content review.
Jung Yong-wook, executive director of Samsung Display's IT Strategy Marketing Team, stated, "The OLEDs for laptops that meet True Black 1400 standards showcase Samsung Display's material technology. We will continue to expand our high-performance OLED product lineup for premium laptops."
