利用整个方阵的LED背景灯光的屏幕效果要好很多，出了提供更多的统一亮度，他们同样能满足当屏幕需要变暗时所需要达到的效果。
Screens that use a full-array of LED backlights are much better. Apart from giving more uniform brightness, they allow the screen to be dimmed selectively in places where a scene needs to be dark.

星云旋转和转动的速度降了下来，亮度也变暗了。
但但亮度变暗也可能是由食双星引起的，其从地球上看，两个星球出现在同一个轨道的边缘，因此每一次循环，每一个星球都会经过另一个的前方。
But dimming can also be caused by an eclipsing binary, a pair of stars in an orbit that appears edge on as seen from Earth so that each star passes in front of the other once per cycle.
它的表面多年来由于尘埃和宇宙光破坏它的原始亮度，它应该变暗。可它现依然保持着青春的光辉。
Its surface should darken over the years as dust and cosmic rays mar its pristine whiteness, and yet it's kept its youthful sheen.
除了提供更为一致的亮度，全阵列led背光能使屏幕上那些影像需要变暗的地方选择性的暗下来。
Apart from giving more uniform brightness, a full array of LED backlights allows the screen to be dimmed selectively in places where a scene needs to be dark.
