Unlike most screens, which require time to warm up before reaching maximum brightness, the LED-backlit screen shines instantly and uniformly. And a LED backlight gives you more control over screen brightness. This way you can fine tune the iMac screen to adapt to ambient lighting conditions, even in the darkest room.
