Samsung Galaxy S27 Pro and Ultra may add DC dimming
A leak says Samsung may add DC dimming to the Galaxy S27 Pro and Galaxy S27 Ultra.
These are expected to be high-end phones in Samsung’s next Galaxy S series.
Current Galaxy S26 models use a brightness method called PWM, which rapidly switches screen pixels on and off.
Some people are sensitive to that flicker and can experience eye strain or headaches.
DC dimming adjusts the power to the pixels instead, which can reduce flicker.
It may affect image quality at very low brightness, so Samsung could use a hybrid system that switches methods.
Samsung has not confirmed the rumored change, and the sources do not give a release date for the phones.
Samsung may add DC dimming to the Galaxy S27 Pro and Galaxy S27 Ultra, according to leaks reported by two outlets.
The feature could reduce OLED flicker and help users who experience eye strain or headaches with PWM dimming.
The current Galaxy S26 series uses PWM and has no DC-like flicker reduction option, according to Digital Trends.
A hybrid system that uses DC dimming at some brightness levels and PWM at others may be needed.
The reports are based on leaks, and Samsung has not confirmed the feature in the supplied articles.
