A display system is described having a plurality of display units, wherein each of the display units is movable between at least a first position and a second position, and wherein each display unit is provided with at least a first light emitting element. Each display unit may be configured to be rotatable about an axis thereof, such that the first position is defined as a first angular position of rotation about the axis, and the second position is defined as a second angular position of rotation about the axis. A method of operating a display system having a plurality of display units is also described, wherein each of the display units is movable between at least a first position and a second position, and wherein each display unit comprises at least a first light emitting element, the method including: moving the display units from the first position to the second position, thereby exposing a first display surface; controlling emission of light from the first light emitting element of each of the display units; and returning the display units to the first position.
