What is the dimming method of the Xiaomi 15 Ultra?
The default dimming method of the Xiaomi 15 Ultra screen is DC dimming in high brightness, and 1920Hz high-frequency PWM dimming in low brightness.
For your reference, here is more information about the default dimming method:
1. DC dimming (direct current dimming): At high brightness, using DC dimming can reduce the flickering of the screen, provide a more stable brightness output, avoid the visual fatigue that can be caused by low-frequency PWM dimming, and is especially suitable for long-term use;
2. 1920Hz high-frequency PWM dimming: When the brightness is low, high-frequency PWM dimming is used to adjust the screen brightness. This method uses higher-frequency pulse modulation to reduce the flicker perceived by the human eye. Although there is a certain amount of flicker, it does not cause obvious discomfort due to the high frequency.
