Abstract: A wall module of a modular LED wall includes an array of LED panels and a truck for supporting the array of LED panels and providing mobility thereto relative to a stage surface. The truck may include a support assembly including a first support base fixed to the array of LED panels, a second support base engageable with the first, and a plurality of ball bearings arranged between the first and second support bases to allow relative movement of the first and second support bases in a plane parallel to the stage surface, a plurality of omnidirectional wheels arranged to enable omnidirectional movement of the second support base along the stage surface, and one or more actuators operable to adjust a height of the support assembly at a plurality of positions on the support assembly to enable leveling of the support assembly relative to the stage surface.
