Galaxy S27 Pro and S27 Ultra rumored to debut DC dimming
A rumor claims the Galaxy S27 Pro and S27 Ultra would be Samsung's first phones with DC dimming, while the standard models may use M14+ OLED material.
Samsung's Galaxy S27 Pro and Galaxy S27 Ultra are rumored to become the company's first smartphones to offer DC dimming, according to a report from GSM Arena. The claim, which remains unconfirmed, points to a display change for the two higher-end models in the upcoming Galaxy S27 series.
The Galaxy S26 Ultra, by contrast, relies on PWM (pulse-width modulation) to adjust brightness. DC dimming is an alternative method that varies the current directly rather than pulsing the backlight, and is often cited by users sensitive to flicker.
The same rumor states that the Galaxy S27 Pro and Galaxy S27 Ultra would use Samsung's M16 OLED material, while the regular Galaxy S27 and Galaxy S27 Plus would use M14+. The Privacy Display feature introduced on the Galaxy S26 Ultra is also rumored to return on the S27 Pro and S27 Ultra.
Background
Samsung Display was previously reported, in October 2025, to be preparing to begin manufacturing displays for the Galaxy S27 series soon. The Privacy Display feature made its debut on the Galaxy S26 Ultra.
