• Samsung is reportedly exploring a display upgrade for the Galaxy S26 Ultra, using the CoE tech it first used on the Galaxy Z Fold 3.
• CoE tech removes the polarizer layer in the OLED and adds a color filter and a black PDL.
• This display technology helps make the display panel thinner, brighter, and more efficient, possibly opening the door to a thinner smartphone.

The Galaxy S25 series has not even launched yet, and we’re already starting to hear more rumors about the Galaxy S26 series. A new report suggests that Samsung is exploring a display upgrade on the Galaxy S26 Ultra, possibly making it thinner, brighter, and more efficient.

A report from the Korean publication The Elec*states that Samsung is planning to apply Color-filter-on-thin-film-encapsulation (CoE) technology to the Galaxy S26 Ultra, which will be released in 2026. CoE is a tech that replaces the polarizing plates in OLEDs with a color filter and changes the general Pixel Define Layer (PDL) to a black one.
