You see the gap in between here? That gap exist where the LCD sits beneath the MCU board.

Using a bit of highly precise de-soldering technique (left quite a few melted marks btw), you have to desolder the 4 contact points in order to separate the board from the LCD panel

P/S: Credit to my peer who helped me out. Fortunately it wasn't me. Else I would have left quite a larger mess :)
