Not sure if this is prevalent on other screens, but I just noticed it while I had the Mobile Safari debug bar up.

Not sure what this problem is called, but if you open this page and make sure your iPad in portrait. You should be seeing darker grey areas directly above the red bars. Tap anywhere to toggle the red bars.

I've tried taking a photo but all I get is what I think is a rainbow effect from the polarising filter from the LCD. But I can see the effect on the live view on the camera so it's not just my eyes.

Anyway, this is a call to iPad (3) owners, since the one iPad 2 I've tried it on doesn't exhibit this effect.

Please post your results.

I do see the darker gray "echoes" in portrait mode, and not in landscape. They are fairly subtle though and almost look like an optical illusion but of course they disappear when the red bars are not there.

This is on an iPad 3.

On my iPad 1, the gray is solid in both orientations.

I see them on my iPad 3 but not with my iPad 2. Very interesting. I also put the 1 and 2 side by side. The red on the iPad 2 was really orange compared to the 3.

I cant imagine how this looks, pics?

I'll post some photos once I can get the stupid thumbnail links working correctly.. On my new iPad, it was only noticeable because I knew about it before. Showed it to a friend of mine, and he never noticed it at all.

Here are the photos...

Are we sure that grey bar isn't transparent?

If you look at it on a desktop/laptop screen, you do not see the leakage. Also, if you rotate the iPad to landscape mode, the bleed disappears as well. IF the grey bar was transparent, then you would be able to see it regardless of which device/screen/screen orientation you used.

I can see a very slight effect. Even then, my eyes get saturated with the red and it becomes more difficult to see.

Most likely I would never have noticed the effect, unless I started an optical illusion site ;)

I now understand what you mean, I also see that "ghost" effect on the Galaxy Note and Tab7.7 Im not sure what is causing it.. must be signal cross talk?

I almost always notice that on the Tab7.7 when I bring up the settings menu while Im web browsing a site.

It's almost subtle enough that you wouldn't know it was there unless you were looking for it. Those photos I took are basically as close to what I was seeing as possible from a camera - that's how mild the bleedthrough is. But I think that's a function of the red bars themselves moreso than how the iPad screen was designed. As EarlZ pointed out, you can see this on other devices as well.

I find it is easiest to see and rule out illusions if you place an opaque object like part of a blanket over the screen except the gray area. Then you can tap the gray area to toggle the red bars on and off even though you can no longer see them.
