Samsung may be preparing one of its biggest display overhauls yet for the upcoming Galaxy S26 Ultra, according to a new report from ET News. The top-end model in the 2026 lineup is expected to debut with new OLED technology that promises higher brightness, better efficiency, and slimmer panels—though these upgrades may not reach every model in the series.
The S26 Ultra will reportedly use Samsung Display’s M14 material set paired with CoE (Color filter on encapsulation) technology. Together, these changes could push brightness beyond 2,600 nits, or deliver the same brightness with lower power consumption.
Unlike current M13-based panels, which use polarizers that add thickness and increase energy use, CoE builds the color filter directly into the OLED encapsulation layer. A new “Black Pixel Define Layer” further reduces reflections, improving contrast. The M14 upgrade also reportedly introduces Deuterium hosts across all red, green, and blue emitters, improving efficiency and extending panel lifespan.
Interestingly, Apple’s iPhone 17 series is also rumored to use M14, but Samsung’s addition of CoE could give its Ultra model a clear edge. There’s also talk of extra features like a “Private Display” mode, limiting viewing angles to protect on-screen content from prying eyes.
However, the report suggests that only the S26 Ultra will get these upgrades. The Galaxy S26 Pro and S26 Edge are expected to stick with M13 panels, continuing Samsung’s trend of reserving its most advanced tech for the Ultra tier.
Samsung hasn’t confirmed these details, but if accurate, the Galaxy S26 Ultra could set a new standard for flagship displays when it launches in early 2026.
