Galaxy S27 Pro and Ultra may add DC dimming, leak says
A leak says Samsung’s Galaxy S27 Pro and S27 Ultra may be the company’s first phones to offer DC dimming.
The phones have not been announced, and the feature is not confirmed.
Most displays adjust brightness using a method called PWM, which rapidly switches light on and off.
Some people are sensitive to that flickering and may experience eye fatigue or headaches.
DC dimming changes the voltage supplied to the light source instead, though it can be harder to use with modern display features.
The phones may still use PWM at low brightness as part of a hybrid system.
The leak also says the Pro and Ultra may retain Privacy Display, while Samsung’s regular S27 and S27 Plus may use a different OLED material; no further details or next steps are given.
A leak claims Samsung’s Galaxy S27 Pro and S27 Ultra may add DC dimming.
The feature adjusts voltage to dim a display and can reduce flicker compared with traditional PWM dimming.
The report says the two models may use Samsung’s M16 OLED material, while the regular S27 and S27 Plus may use M14+.
Privacy Display, introduced on the Galaxy S26 Ultra, is also reportedly set to continue on the Pro and Ultra models.
Samsung has not confirmed the reported display features.
