Otherwise, an excessively large gap would lead to the illuminants of adjacent display modules at the corresponding edge of the respective display surface having a significantly greater distance from one another than the distance between the matrix-like distributed illuminants. This distance, which is increased by the gap, leads to an optically visible gap, which is recognizable as a non-illuminated area, so to speak as a black line in the displayed image.
