MacBook - Ghosting Issue

So I've had my macbook for about 6 months now and it seems to developed what I can only describe as a ghosting issue on the screen. It's pretty annoying and I was just curious if anyone knew if something like this might be covered by applecare. I'll try to post a picture of it but I'll probably be taking my macbook in to the apple store in the next weeek or two. The issue is only really annoying when viewing a dark background which makes it pretty prominent.
