What are the dimming methods of the Xiaomi 14 Ultra’s screen?
The Xiaomi 14 Ultra offers high brightness with DC dimming technology and low brightness with high-frequency PWM (1920Hz) dimming technology.
In this dual dimming method, the Xiaomi 14 Ultra can offer several advantages:
1. It can reduce visual fatigue and eye discomfort. Using DC dimming at high brightness levels avoids the flickering issues that PWM dimming will cause. DC dimming adjusts brightness by directly regulating the backlight voltage, which tends to be easier on the eyes without noticeable visual fatigue or discomfort. At lower brightness levels, PWM dimming adjusts brightness by rapidly switching the backlight on and off at a high frequency. While effective for dimming, PWM can introduce flicker, which will cause visual discomfort or eye fatigue;
2. DC dimming is generally more energy-efficient than PWM dimming because it does not require frequent switching of the backlight at different brightness levels. This efficiency advantage can significantly reduce power consumption over prolonged device usage.
