Use a thin plastic film or pick for separation. To facilitate the process, you can use isopropyl alcohol. It is often the most difficult to pass the tool between the parts to be divided. Choose the far edge from the FFC cables or buttons.
Do not use a lever or any force for separation that could damage the elements inside.
