Samsung Galaxy S26 Ultra’s display to be brighter and more efficient | Infinium-tech

Samsung is now rumored to implement color filter on encapsulation (CoE) technology on the screen of its Galaxy S26 Ultra, which is scheduled to be launched in about a year. This news has come from Samsung’s home Korea.

CoE has been used in Samsung’s Galaxy Fold line since the Z Fold 3, but this will be the first time the company will use it in a slab-style device that doesn’t fold.

Note that the report only mentions the S26 Ultra, so we assume that means the S26 (if it exists) and S26+ won’t get it. That said, the rumor claims that COE will spread to more candybar-style smartphones in the future, so it won’t be exclusive to Ultras forever (as Gorilla Glass armor seems to be).

So if you’re wondering what CoE is, it replaces the polarizer with a color filter, thus improving light transmittance and making the OLED panel thinner in the process. Samsung has also changed the usual Pixel Define Layer (PDL) to a black PDL, which reduces light reflected inside the panel.

This is necessary as this was the primary function of the removed polarizer – which had the downside of reducing brightness by over 50%. It’s not a color filter thing but reflections still need to be addressed, hence the black PDL.

This means that the display will be comparatively brighter that does not use CoE and black PDL, and will be more efficient as well. The Galaxy S24 Ultra’s panel can already reach a peak brightness of 2,600 nits, and that means the S26 Ultra could go even further, at least in theory.
