Abstract

A method of operating an organic light-emitting component having first and second electrodes that have arranged between them an organic functional layer stack having at least one organic light-emitting layer that, during operation, produces light emitted via a luminous area, the first and second electrodes and the organic functional layer stack are in an extensive form, in contact with the first electrode, at each of two opposite edges of the first electrode a respective conductor track is arranged that extends in a longitudinal direction along the respective edge, the two conductor tracks have contact made with them on a same side of the first electrode by a connection element so that during operation there is a voltage drop in each conductor track in the longitudinal direction, which voltage drop brings about a luminous density gradient on the luminous area in a direction following the longitudinal direction.
