What are the dimming methods of the Xiaomi 14T Pro’s screen?
The Xiaomi 14T Pro supports PWM dimming and DC dimming. High brightness adopts DC dimming, while low brightness adopts high-frequency PWM dimming.
In this dual dimming method, the Xiaomi 14T Pro 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. PWM dimming adjusts brightness at lower brightness levels 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 more energy-efficient than PWM dimming because it does not require frequent backlight switching at different brightness levels. This efficiency advantage can significantly reduce power consumption over prolonged device usage.
