Samsung Display is currently exhibiting new OLED technology at Mobile World Congress in Barcelona that the company says can reach 5000 nits of peak brightness. These small displays, most likely optimized for mobile devices, build on the design used in Samsung’s Eco2 OLED panels. These new panels, along with the Eco2, do away with the traditional polarizer layer that rejects external light at the cost of brightness. Samsung explains that these new panels have been optimized to fight external light while preserving brightness using a technique called on-cell-film (OCF)/Color filter On Encapsulation (COE).

“The maximum brightness of 5,000 nit can be achieved when the on-pixel-ratio (OPR), which measures the percentage of active pixels on the screen, is at 10%,” Samsung Display explains to FlatPanelsHD. “It can also reach over 3,000 nits under normal use, such as watching videos. A display with OCF technology provides a screen 1.5 times brighter than a display with a polarizer while maintaining the same power consumption.”
