It's an undeniable fact that every time a new Apple iDevice comes out, a day or two goes by and then a number of reports always come in about issues that early buyers find. On the iPhone 4, it was "Antennagate," which exploded into an issue that lasted months. The iPad 2 has not escaped the "effect."

There are two issues, both related to the screen. The first one is reminiscent of a similar one when the iPhone 4 was launched. Some users have observed a faint yellow tinge to the screen in some areas.

With the iPhone 4, it was eventually explained as a bonding agent used in the construction of the iPhone 4. It's likely this is the same issue as in that case and will go away once the agent has time to set.

The second issue relates to a small amount of light bleeding onto the screen from the edge of the iPad 2 when watching a dark scene in a video or using an app with a black background. It can be handled by adjusting the screen's brightness, if necessary.

It's not uncommon in LCDs of all sorts for this sort of bleeding to occur. It's also true that people want their products to be "perfect," especially iDevices.

You can watch a video of the screen bleeding issue below.

this happens with mass produced products, only bad thing is the people having these problems will have to wait a least a month before they can get a new ipad.

Screen bleed issues are inherent to *all* LCDs, although that's a pretty bad case. An LCD asked to display a black screen turns the display black but can't shut off the backlight. As a result, you end up with a black screen that's being hammered with light from the other side.

OLEDs bypass this because they don't require backlighting. If you want to get rid of it in the computing world, you typically have to pay for a high-end monitor. TN panels tend to backlight the most (they typically stress high contrast ratios and "brightness" the most) followed by S-PVA's and SIPS. That's not an absolute distinction--I'm sure there are good TN panels that only suffer from minimal backlighting, etc.

Whether or not Apple will actually take these devices back remains to be seen. The company could claim that the backlight issue is caused by the technology in question and then try to claim that hey, everyone else has this problem, too. It's worked for them before, after all.
