What is DC Dimming ?

DC dimming essentially controls the brightness by varying the power supplied to the circuit. Since Power = Voltage x Current, increasing or decreasing either of these inputs will vary the power supplied to the display panel, and thereby its brightness.

DC dimming uses a continuous current, which means the display mostly stays on all the time. (It might still exhibit some alternating as a result of the display's refresh rate, which I think is what's happening with the slow-moving line in our video, but I can't be sure.) That constant illumination gets rid of any issues which the rapid flickering might cause, it often allows displays to get far dimmer than PWM-based cousins, and it also photographs much better

PWM isn't the only cause, low refresh rate (below 60Hz) display or low refresh rate videos can also add flicker. Another factor is scrolling or fast animations on low refresh rate displays.

To protect your eyes from flicker, avoid using your phone in a dark ambiance as far as possible. You can also opt for high refresh rate screens and monitors (greater than 120Hz) at the workplace.

That's All for the day regarding DC Dimming Feature and its Working and any doubts regarding let me know in comment section
