Samsung Display’s QD-OLED: Key Highlights at CES 2025

Samsung Display unveiled the winning keywords to strengthen its QD-OLED business at CES 2025: ‘Brightness, Highest, Fastest.

“Brightness” represents the industry’s first TV OLED to achieve 4,000 nits.”

In 2025, QD-OLED achieved an industry-first high brightness of 4,000 nits by altering its OLED structure. It is reported that the structure was changed from 4-stack to 5-stack. The 5-stack QD-OLED includes an additional green (G) layer to enhance efficiency, resulting in a composition of Blue-Blue-Green-Blue-Green.

‘Highest’ refers to a 27-inch OLED monitor manufactured using deposition technology, achieving a resolution of 160 PPI. Although JOLED (now part of JDI) previously achieved 204 PPI with inkjet printing, this is the world’s first high-resolution product using deposition technology. Samsung Display aims to achieve 220 PPI for 27-inch displays in the future.

Another innovation in monitors is ‘Fastest.’ To target the growing gaming audience, Samsung Display has developed an OLED monitor with a 500Hz refresh rate. This monitor features no motion blur and an extremely fast response time, allowing gamers to keep up with the rapid pace of gameplay seamlessly.
