- 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 light efficiency by 1.3 times and doubles the life of the panel
Samsung Display has introduced its QD-OLED Penta Tandem technology with a five-layer organic light-emitting structure designed to improve brightness and efficiency.
Multi-layer stacking allows higher pixel density within the same panel size, reducing the light-emitting area of each pixel.
Efficient dispersion of energy across the layers is essential to maintain stable lighting and consistent performance.

This approach is central to Samsung’s push for premium 4K and 5K displays, where high resolution and vivid images are essential for games and professional applications.
The company’s 27-inch UHD (3840 x 2160) panel, launched in 2025, reaches 160 pixels per inch, marking the highest pixel density for self-emitting gaming monitors.
By increasing the number of organic layers from four to five, the luminous efficiency is improved by 1.3 times while the lifetime is doubled, enabling the panels to achieve maximum brightness levels of 1,300 nits for displays and 4,500 nits for televisions, measured at 3% OPR (On Pixel Ratio).
Samsung claims that the high brightness does not come with additional power consumption, a key aspect of their new premium displays.
Panels using the QD-OLED Penta Tandem can achieve VESA’s DisplayHDR True Black 500 certification, which measures HDR performance, including the ability to produce deep black levels.
The certification calls for a black level of 0.0005 nits or lower, while achieving a maximum luminance of 500 nits at 10% OPR – currently the only 31.5-inch UHD display to meet this standard is based on Samsung Display’s Penta Tandem panel.
This performance indicates a focus on delivering consistent visual quality in advanced business monitor applications as well as gaming setups.
Samsung Display plans to expand the Penta Tandem technology to a wider range of panel sizes this year and deliver flagship displays and TVs to larger customers.
After 27-inch UHD panels and 31.5-inch UHD screens, the company will release a 49-inch Dual QHD (5120 x 1440) panel.
The technology has already been implemented in top-tier TVs, and while the Penta Tandem improves brightness, efficiency and longevity, its impact on overall display performance remains uncertain.
“Multilayer 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 Large Display Marketing Team at Samsung Display.
“Penta Tandem, built on nearly five years of QD-OLED mass production experience since 2021, represents the ultimate choice for customers looking to demonstrate the premium value of QD-OLED.”
