LED not LCD

4 posts in this topic

I've just been listening to the newest Maccast, and I hate to correct you this early, but it's LED, not LCD. Just wanted to let you know.

I noticed that too. To elaborate the display is made from LCD technology and is lit with LED technology. The new LED backlighting is great for many reasons, wanna hear them? The biggest reason to like them for notebooks, or simply your electric bill, is the lower power requirement compared to traditional LCD backlighting. The second thing is that they're better for the environment both in production and when they hit the landfill. Last and most geeky they give better picture. Even black regions on traditional LCD screens have light being supplied to them, that's why you usually see gray and not a true black. When you put tons of individual LEDs behind the screen you can turn off any lights that are behind dark portions of the screen allowing for inky blacks. Turning off the lights also saves power. Thats the short and simple run down on why we like LED backlighting.

I wonder what happens (and what you can do about it) when you have a dead LED. With one back light this doesn't happen, but with individual LEDs you could have both dead pixels (non-responding LCD shutters) and dead LEDs. So this could be a drawback of the new technology.

LEDs last WAY longer than the lights in LCD displays now. Right now the technology is similar to a fluorescent bulb. You have an interesting concern, but really, you shouldn't have anything to worry about. Plus even if one had some sort of defect and died early it should be pretty easy for someone to open the display and solder in a new one. Not exactly a DIY project for most people, but for an Apple tech, should be no biggie.
