Overview
- Samsung trademarked 'QD‑OLED Penta Tandem', formalizing a five‑layer emitter stack already used in select 2025 monitors and TVs with broad 2026 deployment planned.
- The company claims roughly 1.3× higher luminous efficiency and a twofold increase in lifespan versus last year’s four‑layer QD‑OLED design.
- Peak brightness is quoted at up to 4,500 nits for TVs and up to 1,300 nits for monitors, measured on a 3% window.
- Panels built on Penta Tandem enable VESA DisplayHDR True Black 500 certification, which requires ≤0.0005‑nit black levels and 500 nits at 10% OPR.
- Samsung lists 27‑inch UHD, 31.5‑inch UHD, 34‑inch WQHD and 49‑inch Dual‑QHD panels for 2026 coverage, and positions the tech against LG Display’s Tandem OLED and Tandem WOLED approaches.
