Samsung Display has introduced its new Penta Tandem OLED technology. It is designed to make screens brighter and last longer than before.

The word “Penta” means five. This technology uses five layers of light-emitting material inside the screen. Before, Samsung used four layers. By adding a fifth layer, the screen spreads out the energy better. This reduces wear on the screen and makes it last longer. Samsung says this new structure doubles the expected lifespan of its panels.

Penta Tandem OLED is especially useful for high-resolution monitors and TVs, where each pixel is smaller and needs to shine brightly. Samsung’s 27-inch 4K monitors with this technology reach 1,300 nits of brightness, while TVs can hit 4,500 nits under certain conditions. The extra layer also helps manage heat, which is important for dense screens.

Samsung’s new panels have also earned recognition. Their 31.5-inch UHD monitor is the only one of its size to meet the VESA DisplayHDR True Black 500 standard. This certification shows the screen can produce very deep blacks while keeping brightness high.

Penta Tandem OLED first appeared in gaming monitors, but now Samsung is using it in more products. This includes 34-inch ultrawide monitors, a 49-inch Dual QHD monitor, and high-end TVs introduced since 2025.
