dimming zones
The individually controlled regions of an LCD backlight that enable local dimming — more zones mean finer contrast control.
Full Definition & Technical Explanation
Dimming zones are the separate segments of a backlight that can be brightened or dimmed on their own. A display with a few dozen zones can only coarsely shape light, while premium mini-LED panels pack hundreds or thousands of zones for finer control.
More zones generally reduce blooming and improve local dimming, especially with HDR content.
