Hi, sammy123! Welcome to iPF!
Before you go to the Apple Store, here's something you could try:
Reset your iPad, if you haven't done so already. This won't remove data or settings, but maybe solve your issue. Press and hold Home and Power button until the Apple logo appears. Then release both and let the iPad power up on it's own.
I've seen this "method" help others with screen problems as well:
Turn your device upside down, and slap it on it's back cover three or four times with the flat of your hand. This may sound strange, but it helped a few times, actually.
If this doesn't help, backup and restore the device this way:

Is it still under warranty? Then it's certainly worth taking it to the next Apple Store, if the above didn't help. You should make a backup of the iPad's content in any case.
