Samsung Display has unveiled a 5,000-nit OLED panel featuring Color filter on Encapsulation (CoE) technology at MWC 2025.
CoE, also referred to as On-Cell Film (OCF), replaces the traditional polariser plate with a colour filter, which enhances light transmittance while reducing power consumption. Samsung first introduced this technology in 2021 with the Galaxy Z Fold 3.
With an on-pixel ratio of 10%, the new panel achieves a peak brightness of 5,000 nits – 1.5 times brighter than current flagship smartphones.
This high brightness level ensures superior visibility even in extreme outdoor conditions such as desert environments. Under normal usage, such as video playback, the display can still deliver over 3,000 nits of brightness.
Samsung Display’s OCF technology, initially developed for foldable smartphones, has been expanded to standard smartphones, tablets and laptops. It has been integrated into devices such as Realme’s GT7 Pro smartphone and Lenovo’s ThinkBook Plus G6 Rollable laptop.
Samsung Display also showcased its latest innovations at MWC 2025, including an 18.1-inch flexible OLED panel designed to fold into a suitcase-like form factor with a built-in handle; a polygon foldable panel featuring a 3.38-inch rhombus-shaped OLED external display; and OLED tiles, a modular display system combining ten 6.8-inch RGB OLED panels with two 31.5-inch QD-OLED screens, with ultra-thin bezels measuring just 0.6mm.
Samsung Display emphasised that transitioning from LCD to OCF OLED panels can have significant environmental benefits. The company estimates that replacing 1 million LCD panels with OCF OLED panels would result in a reduction of 474 tons of CO2 emissions due to decreased plastic usage.
