Radiation-emitting component having adjustable acoustic effect and process for preparing the same

The invention relates to a sheet-like arrangement with a radiation-emitting component comprising at least one radiation-emitting component (9), wherein the device (9) comprises a substrate (1), an anode (2), a cathode (4) and at least one between the anode includes (2) and the cathode (4) arranged active layer (3). The arrangement is characterized in that is present in the two-dimensional arrangement, a plurality of recesses (7) so that the planar arrangement is acoustically designed as microperforated absorber or as part of a micro-perforated absorber.
