Local dimming #Splitting a display’s backlight into individually controllable zones can increase the contrast ratio and provide deeper black levels. This is usually called local dimming or mini-LED. The Pro Display XDR, 12.9-inch iPad Pro, 14-inch MacBook Pro, and 16-inch MacBook Pro all have local dimming. I believe Apple denotes this feature as “XDR display” in their tech specs, because using mini-LED backlights provides local dimming, and it can assist with HDR support.，详情可参考91视频
