Samsung Display Introduces Premium Technology Brand “QD-OLED Penta-Tandem”.

Samsung Display has announced a brand new premium “QD-OLED Penta-Tandem” technology for its five-layer organic light-emitting structure.

Samsung QD-OLED Penta-Tandem Display Comes With Five-Layer Organic Light-Emitting Structure, VESA DisplayHDR TrueBlack 500 Certified & Available Across Complete Lineup This Year

Press Release: Samsung Display launches ‘QD-OLED Penta Tandem’, a brand new premium technology built on its proprietary five-layer organic light-emitting structure, a core innovation unique to its QD-OLED panels.

Samsung Display announced that it has completed trademark registration for the new brand, which was created to highlight the distinctive value of the five-layer organic light-emitting structure applied to QD-OLED panels for premium monitors and TVs. “Penta” comes from the Greek word for the number five.

QD-OLED expresses color using quantum dots that respond to light, with a blue-emitting layer serving as a light source due to its high energy in the visible spectrum. Starting last year, Samsung Display increased the blue-emitting layer stack from four layers to five, and applied the latest organic materials, equipping a new generation of QD-OLED that delivers superior image quality, efficiency and peak brightness.

In particular, multi-layered stacks of organic light-emitting materials have emerged as a key differentiator amid increasing competition in the high-resolution monitor market. Achieving higher resolution in the same panel size and increasing pixel density will reduce the light-emitting area of ​​each pixel. Under these technical constraints, effective dispersal of energy applied to organic materials is critical to maintaining high and stable brightness levels.

Samsung Display’s 27-inch UHD (3840×2160) QD-OLED monitor panel, launched last year, achieves 160 pixels per inch (PPI), the highest pixel density among auto-illuminating gaming monitors. Tandem Penta QD-OLED forms the core technological foundation of this breakthrough. To date, Samsung Display is the only company that mass-produces 27-inch UHD self-emissive screens with 160 PPI specifications.

As the number of organic material layers increases, the light efficiency increases, allowing higher brightness at the same power level or maintaining the same brightness with lower power consumption. This is similar to five people carrying a load previously carried by four people, allowing for greater endurance or the ability to lift something heavier.

Compared with last year’s four-layer QD-OLED, Penta Tandem increases light efficiency by 1.3 times and extends lifespan by 2 times. As a result, products equipped with QD-OLED Penta Tandem technology achieve industry-leading peak brightness of 4,500 nits for TVs and 1,300 nits for monitors, based on an OPR of 3% (On Pixel Ratio, the ratio of active pixels among all the pixels that make up the screen).

Panels equipped with QD-OLED Penta Tandem technology enable customers to achieve VESA ‘DisplayHDR™ True Black 500’ certification. True Black certification is a standard that assesses a display’s HDR (High Dynamic Range) performance, including its ability to reproduce deep black levels. To achieve a True Black rating of 500, a display must maintain a black level of 0.0005 nits or lower while achieving a peak luminance of 500 nits (at 10% OPR). Currently, the only DisplayHDR™ True Black 500 certified 31.5-inch UHD monitor is built on Samsung Display’s QD-OLED Penta Tandem panel.

Samsung Display plans to expand its QD-OLED Penta Tandem to all its panel sizes this year, supplying the technology for flagship products from major customers. Following last year’s 27-inch UHD panel and the 31.5-inch UHD and 34-inch WQHD products introduced earlier this year, the technology will be applied to the 49-inch Dual QHD (5120×1440) model. In the TV segment, Penta Tandem has been featured in the top self-emissive TV screen lineup of major customers since 2025.
