So you might have dropped your iPad or not even damaged it at all. This is a common issue as an iPad repairer I see almost every day & in this quick video I explain what is damaged and the solution to fix it.
Please note this happens to all model iPads and can show as lines, multi coloured lines, ink leaking, blobs on the screen, black spots on the screen, green lines on the screen and even pink lines on the screen - there are so many variations but the solution is all the same.
If your a bit confused - drop a comment below and I am more than happy to help
