Abstract: A method for mapping a display wall including a plurality of display modules, each display module including a controller and a port on each side connected to the controller. Each display module is connected to its direct neighbour at each side port. The method includes the steps of powering up the display wall, each display module continuously communicating with its direct neighbour via each side port by sending and receiving tile to tile packets including information on at least the coordinates of the display module, defining a reference position in the display wall, the reference position having a reference coordinate, and defining an incremental direction in the display wall with respect to the reference position. For each display module, continuously updating the display module coordinates by comparing its coordinates to the coordinates of each neighbour following the incremental direction and with respect to the reference position.

Abstract: A tiled display which allows removal of display tiles in a controlled manner as well as access to the back of a display tile of the tiled display without having necessarily an opening in the display tile through which a tool to trigger a release mechanism would have to be inserted. Some of the display tiles can have at least one cylindrical element fastened to the display tile by an intermediary of a fastener positioned at one end of the cylindrical element. The cylindrical element is fixed to such tiles with the fastener. An actuator is provided to pull in the display tile to fit within the plane of the tiled display by activating a non-contact sensor with a dedicated non-contact device in a vicinity of the display tile until the tile slides in. The non-contact device emits a control signal received by the non-contact sensor.
