There is provided an interface system for joining display modules to a framework structure. The interface system comprises a base structure and a holder structure, the holder structure can be attached to the framework, and the base structure can be attached to two or more of the display modules. The holder structure or the base structure are interfaced by a tiltable planar surface and a curved support structure so that the holder structure and base structre are moveable towards each other. A multiple of base structures can be joined via elongated members.
