"Penta Tandem" technology uses five stacked organic layers to dramatically improve OLED lifespan and efficiency.
Samsung Display has introduced its new "Penta Tandem" brand for OLED products, trademarking the technology to address inherent weaknesses of organic screens, specifically lifespan and energy efficiency.
The "Penta" designation refers to the five organic light-emitting layers stacked within the panel. Samsung has been transitioning from a four-layer blue stack to this five-layer version over the past year. This design aims to mitigate issues arising from increased pixel density by distributing electrical energy over a larger area of organic material. The company states this structure doubles the expected lifespan compared to its previous four-layer designs.
This architecture enables high pixel density, observed at approximately 160 pixels per inch in recent 27-inch UHD monitors. These monitors can achieve peak brightness levels of 1,300 nits, while televisions utilizing similar technology are rated for up to 4,500 nits under specific testing conditions.
The Penta Tandem system has facilitated specific industry certifications. Samsung's 31.5-inch UHD monitor is currently the only one in its size category to meet the VESA DisplayHDR True Black 500 standard, which requires deep black levels and 500 nits of luminance.
The technology initially appeared in specialized gaming monitors last year and is now being expanded across Samsung's flagship lineup, including 34-inch ultrawide and 49-inch Dual QHD monitors expected later in the year. In the television market, the "Penta" structure has been incorporated into top-tier lineups since 2025. The long-term durability, particularly regarding "burn-in" over several years of use, will be a key factor for consumers.
