Samsung Display just put a name on its newest QD-OLED upgrade, and it’s one that’s easy to shop around. It calls the tech QD-OLED Penta Tandem, a five-layer organic light-emitting structure meant to squeeze more brightness and longevity out of premium monitors and TVs without cranking power the hard way.
The change centers on the blue emitting layer, the light source in Samsung Display’s QD-OLED approach. The company says it moved from four blue layers to five and paired that with newer organic materials, which helps spread energy across more of the stack. That’s a big deal as high-end monitors chase higher pixel density, since each pixel’s light-emitting area gets smaller and it becomes tougher to keep luminance steady.
Samsung Display says Penta Tandem is set for a wider rollout across flagship sizes this year, including 27-inch 4K, 31.5-inch 4K, 34-inch WQHD, and a forthcoming 49-inch Dual QHD model. It also says the same panel approach has been used in top-tier self-emissive TV lineups from key customers since 2025.
More brightness, less strain
Samsung Display’s headline claims are aimed at the two specs buyers care about, HDR pop and durability. It says the five-layer stack improves luminous efficiency by 1.3x compared to last year’s four-layer design and doubles lifespan. In plain terms, that can mean higher peak brightness at the same power, or similar brightness with lower power draw.
On peak numbers, the company cites up to 4,500 nits for TVs and up to 1,300 nits for monitors, measured at 3% OPR (on pixel ratio). That’s a small highlight window, but it’s still a useful clue about HDR headroom for things like reflections, sparks, and bright UI elements.
The clearest win is 4K monitors
Where this upgrade should matter most is high-resolution screens in smaller sizes, where sharpness and brightness can end up pulling against each other. Samsung Display points to its 27-inch UHD QD-OLED panel at 160 PPI, calling it the highest pixel density among self-emissive gaming monitors, and says it is the only company mass-producing a 27-inch UHD self-emissive display at that 160 PPI spec.
There’s also a standards angle. Samsung Display says panels using the Penta Tandem stack can meet VESA DisplayHDR True Black 500 requirements, and it claims the only 31.5-inch UHD monitor currently certified at that level is built on its panel.
What to look for when you shop
Treat Penta Tandem as a panel-generation marker, not a model name. When new 2026 monitors and TVs get announced, look for that panel callout, then dig into HDR measurements beyond the tiny 3% OPR figure, since larger bright scenes are where heat and power limits usually show up.
If you’re not in a rush, waiting for the next refresh in your preferred size could be the smarter move, especially if you want strong HDR highlights and better long-term panel health.
