- Samsung’s Penta Tandem uses five organic layers to improve brightness and efficiency
- Multi-layer stacking allows for higher pixel density without increasing panel size
- QD-OLED Penta Tandem technology increases luminous efficiency by 1.3 times and doubles panel life
Samsung Display has introduced its QD-OLED Penta Tandem technology, which features a five-layer organic light-emitting structure designed to improve brightness and efficiency.
Multi-layer stacking allows for higher pixel density within the same panel size, reducing the light-emitting area of each pixel.
Effectively dispersing energy between layers is crucial to maintaining stable lighting and consistent performance.
Multi-layer design increases pixel density
This approach is critical to Samsung’s push toward premium 4K and 5K monitors, where high resolution and vivid images are essential for gaming and professional applications.
The company’s 27-inch UHD (3840 x 2160) panel, released in 2025, reaches 160 pixels per inch, marking the highest pixel density for self-emissive gaming monitors.
By increasing the number of organic layers from four to five, luminous efficiency improves 1.3 times while lifetime doubles, allowing the panels to achieve maximum brightness levels of 1,300 nits for monitors and 4,500 nits for televisions, measured with a 3% OPR (On Pixel Ratio).
Samsung claims that high brightness does not come with additional power consumption, a key aspect of its new premium displays.
Panels using QD-OLED Penta Tandem can earn DisplayHDR True Black 500 certification from VESA, which measures HDR performance, including the ability to produce deep black levels.
Certification requires a black level of 0.0005 nits or lower while achieving a maximum luminance of 500 nits with an OPR of 10%; Currently, the only 31.5-inch UHD monitor that meets this standard is based on Samsung Display’s Penta Tandem panel.
This performance indicates a focus on delivering consistent visual quality in high-end business monitor applications as well as gaming setups.
Samsung Display plans to expand Penta Tandem technology to a wider range of panel sizes this year, supplying flagship monitors and TVs to major customers.
After the 27-inch UHD panels and 31.5-inch UHD monitors, the company will launch a 49-inch Dual QHD (5120 x 1440) panel.
The technology has already been implemented in top-tier televisions and although Penta Tandem improves brightness, efficiency and lifespan, its impact on overall monitor performance remains uncertain.
“The multi-layer organic light-emitting structure is not just about adding more layers. It requires deep expertise in selecting materials and optimizing their thickness and combinations,” said Brad Jung, vice president and head of the large display marketing team at Samsung Display.
“Penta Tandem, based on nearly five years of QD-OLED mass production experience since 2021, represents the best option for customers looking to demonstrate the superior value of QD-OLED.”
