Apply a suction handle to the bottom of the screen.

If your display is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken screen.

Pull the suction cup up with strong, steady force to create a gap.

Insert an opening pick into the gap.
