Galaxy S27 Pro and Ultra Reportedly Switch to Flicker-Reducing DC Dimming

Samsung’s Galaxy S27 Pro and S27 Ultra will reportedly support DC dimming, a brightness-control method meant to reduce the screen flicker some people find tiring on OLED phones. The claim comes from tipster WalleGalaxy on X, who said the two displays support the feature and that Samsung is working with “various safety firms” on the eye strain seen in earlier models. The tipster also said the Eye Comfort Shield software feature will keep improving.

Samsung’s phones have so far relied on PWM, which adjusts brightness by switching the pixels on and off very quickly. That can bother sensitive users, especially at low brightness. DC dimming instead lowers the current going to the pixels, which avoids that strobing effect. Samsung has said the Galaxy S26 lineup has no flicker-reduction option, so the S27 Pro and Ultra would be its first flagships with it if the leak is accurate. Other brands, including Motorola and Xiaomi, have offered similar options for years.

The post doesn’t explain how the system would behave across brightness levels, and DC dimming doesn’t guarantee a completely flicker-free screen, since OLED phones can use hybrid approaches. The panel generations also come from earlier reports rather than from this leak.

The display change adds to what has been reported for the pair so far, including LPDDR6 RAM and UFS 5.1 storage and the Galaxy S27 Pro’s BIS certification. Samsung hasn’t announced a launch date for the S27 series, which is expected in 2027.
