PROBLEM TO BE SOLVED: To provide an improved addressable display, and to provide an improved cooling layout, especially, for a tiled display or a segmented display. SOLUTION: This invention provides a layout for an electroluminescent display 10 including a packaged semiconductor light emitting element 12 having a luminescent display side 16. A heat sink 22 is arranged on the rear side of the light emitting element 12 facing the display side. Electric connections 28 from the light emitting element 12 pass through the heat sink 22. A driving circuit 30 for the light emitting element 12 is connected thereto via the electric connections 28 and is spaced from the heat sink 22, and in order to use a cooling liquid and to make it pass through there, at least one cooling channel 34 is regulated between the heat sink 22 and the driving circuit 30.
