Samsung has announced a groundbreaking new OLED panel, capable of reaching an astonishing 5,000 nits of peak brightness. It has the potential to redefine the display standards for mobile devices such as smartphones, smartwatches, and laptops. The company is showcasing this cutting-edge panel at the MWC 2025 expo in Barcelona, Spain.
A significant leap in brightness and power efficiency
The new OLED panel utilizes something called an On-Cell Film (OCF) technology, a Samsung innovation that eliminates the need for a polarizer. Polarizers, traditionally used to block ambient light, reportedly reduce OLED brightness by up to 50%. By removing the polarizer, Samsung has achieved a display that is not only brighter but also more energy-efficient.
The OCF II OLED panel can deliver 5,000 nits of peak brightness in a 10% window (10% of the screen area), a significant improvement over competitors’ claims, which is often measured at a much smaller window size (1% or 5%) to achieve similar brightness levels.
For everyday use, such as watching movies, the panel can reach up to 3,000 nits, which is still pretty good, and is higher than what the Galaxy S25 Ultra can achieve in the same situation.
But it’s not all about brightness. In fact, improving the power efficiency is more important than improving the peak brightness, as most of the devices using these displays run on batteries. Samsung claims that these brightness levels are achieved with 1.5x higher efficiency compared to previous panels, meaning the same brightness can be maintained with just 63% of the power consumption. This results in longer battery life, reduced heat generation, and an extended display lifespan.
Slimmer design and broader applications
The removal of the polarizer also allows Samsung to make its OLED panels 20% slimmer than conventional designs. This technology was first introduced in the Galaxy Z Fold 3 and is now being extended to bar-shaped smartphones and even rollable laptops.
While it may seem just another iterative improvement in brightness and efficiency, it’s more than that. Samsung isn’t the single key player in the display industry. Chinese display makers like BOE have made significant improvements and achieved a significant improvement in both brightness and efficiency in the last couple of years. This development from Samsung Display is expected to increase the competition and motivate its competitors to focus more on innovation, which, in turn, will benefit end users.
According to Joohyung Lee, Head of Mobile Display Business at Samsung Display, the company aims to maintain its leadership in the display industry through continuous innovation.
