Abstract
Described is a method for power sharing of a display wall, in particular of a LED display wall having a plurality of display modules, and a plurality of N power supply units, each for driving a number of display modules, whereby during a failure of a first power supply unit of the plurality of N power supply units, the outputs of other power supply units are linked together such that the module or modules driven by the first and failed power supply continue(s) to operate, by redistribution of power from the other power supply units. Power sharing is also described in the context of a method for controlling the status of a display wall, in particular of a LED display wall, controlled by a central unit. The method includes collecting status and/or diagnostic information of the display wall inputted to the central unit; converting the status and/or diagnostic information to a picture; and displaying the picture on the display wall.
