Strahlungsemittierendes Bauteil mit akustisch einstellbarer Wirkung und Verfahren zur Herstellung derselben

The invention relates to a planar arrangement comprising a radiation-emitting device having at least one radiation-emitting component (9), wherein the component (9) comprises a substrate (1), an anode (2), a cathode (4) and at least one active layer (3) arranged between the anode (2) and the cathode (4). The arrangement is distinguished by the fact that a plurality of cutouts (7) are present in the planar arrangement, such that the planar arrangement is embodied acoustically as a microperforated absorber or as part of a microperforated absorber.
