Test yours here:

Apparently it is quite normal according to this site:

http://www.techmind.org/lcd/

The following test patterns deliberately excite only one polarity-half of the inversion pattern for some common schemes, and one of them should cause your screen to flicker. This is not a fault with the screen, but enables you to find out which inversion scheme your screen uses.

Mine flickers on 4a and according to techmind.org, the panel I'm using (9CAC) uses "Line-paired RGB sub-pixel dot-inversion".

How about you?
 
It's not a problem. Every LCD does it, I think to prevent burn-in. Mine flickers on 4a or 4b depending on where exactly I scroll to on the page. Scrolling up or down slightly switches it.

The only time it would be a problem is if you see flickering on something not designed to show it, like a solid color background. I would say it is a problem on my iPod Touch, though I don't know if it is the LCD or the backlight or something else. It is worst on pattern 5, but only at some zoom levels, and I can't get it to show exactly at native resolution.
