A calibration device for a two dimensional (2D) image display module includes a securing member adapted to secure the lens to the box and having extensions extending out from the box, multiple first elongated holes in opposite sides of the backboard to correspond to the extensions and multiple second elongated holes in opposite sides of the lens to align with the first elongated holes of the backboard such that the extensions extending through the corresponding first elongated holes of the backboard are able to extend through the second elongated holes of the lens. A riveting device is provided to allow the lens to be pivotable relative to the box. Pivotal movement of the cam in a cam hole in the lens is able to force the backboard to move linearly and thus relative position between the lens and the backboard is adjusted.
