CCFL Versus LED



Out with the old, in with the new. LED backlighting is now all the rage in monitor design—and why not? Apple made LED technology the golden child of green tech when the company announced in 2007 that it would move to LED backlights and drop traditional cold cathode fluorescent lamp (CCFL) backlighting in its products. The target was mercury, a key ingredient in fluorescent lighting tubes.



Without question, there’s a lot about LED to commend it as a greener technology than fluorescent. Surprisingly, though, few (if any) people have stopped to ask what the relationship is between power savings and image quality. Is there a relationship? We always hear that LED monitors have far better contrast and better color, but is this true, and is there a price to be paid for that superior image?
