Abstract
A shading panel is described for shading light emitting elements of a light emitting diode display system. The shading panel defines a substantially plane panel surface having an upper border and a lower border, the shading panel comprising at least one column of at least two openings aligned according to a column direction, each opening being suitable to receive at least one light emitting element. For each pair of adjacent openings of the at least one column of openings, the shading panel comprises a first shading louver and a second shading louver, the first shading louver being positioned closer to the opening of the pair of openings closest to the upper border, the second shading louver being positioned closer to the opening of the pair of openings closest to the lower border. The height of the first shading louver is smaller than the height of the second shading louver.
