What is the difference between class dc dimming and dc dimming

1, dimming principle difference: DC dimming is by directly adjusting the current of the screen circuit to change the brightness. You can reduce the brightness of the screen by reducing the current to achieve the dimming effect. Class DC dimming is through the algorithm and software to adjust the brightness and color of the screen, indirectly affecting the current. The dimming effect is simulated by adjusting the brightness level and color combination of the screen display.

2, the difference between the impact on the human eye: DC dimming in the dimming process without screen flash, there is no obvious harm to the human eye. Can provide more stable brightness adjustment. Class DC dimming will produce screen flicker in the dimming process, which causes discomfort or fatigue to some people's eyes. Screen flicker can cause visual fatigue of the eyes and even have a discomforting effect on some people.
