While holding down the corners of the iPad, repeatedly pull up on the screen, then ease it back down to weaken the adhesive. This will eventually create a small gap in the seam.

If the edge cools down during the pulling process, reheat the edge with an iOpener before proceeding.

Once you've created a small gap, insert the tip of an opening pick into the gap.

Don't insert the pick more than 2 mm, or you risk permanently damaging the display panel.
