White line in iPad screen corner on lighter colors

There is a white line only in the corner of my ipad screen . the end of it is more white in real life and doesn’t wipe off and doesn’t show up when the screen is off, and is less visible on certain colors. I’m assuming this is display damage? how would one fix this?

It also only shows up on lighter colors. It doesnt show up on black.

You can easily determine if you have a hardware or software issue. A reliable method to confirm a screen or other hardware fault is to take a screenshot when the fault is evident - and then review the captured screenshot image...


When reviewed, if the lines are not present in the screenshot image, then you have demonstrated that you have a hardware fault that, sooner or later, may become sufficiently severe that repair or replacement of the iPad are the only options. If the lines are visible in the screenshot, the something other than hardware will be the cause.


Note: When reviewing the image, rotating the iPad screen orientation by 90°, from Portrait to Landscape, will ensure that the image does not coincide with screen defects if present.

If the test indicates that a hardware fault, a visit to the Genius Bar at your local Apple Store is recommended - where the technicians will be able to test and assess your iPad. This will likely inform your next steps:
