Overview
- Samsung said on Monday that it has begun mass production and full‑scale supply of tandem OLED laptop panels that meet VESA’s DisplayHDR True Black 1400 certification.
- VESA’s True Black 1400 requires 1,400 nits peak brightness at a 10% on‑pixel ratio and black levels of 0.0005 nits or lower, a step up from the previous top tier.
- Samsung’s tandem design stacks two organic emissive layers and new materials to reach panel‑level peaks of up to 1,600 nits in small windows while reducing per‑layer electrical load.
- Lenovo’s Yoga Pro 9i Aura Edition is the first certified laptop using the panel and ASUS, Dell, and MSI are expected to ship models with the new displays in the second half of 2026.
- Vendors and Samsung say the design should improve power efficiency and more than double lifespan versus single‑stack OLEDs, but independent testing on battery impact and long‑term aging is still needed.
