The present invention provides arrangements for electroluminescent displays 10 comprising a packaged semiconductor light emitting element 12 that has a light emitting display side 16. A heat sink 22 is disposed in the region of a rear side of the light-emitting element 12 opposite to the display side. Electrical connections 28 from the light emitting element 12 pass through said heat sink 22. Drive circuitry 30 for the light emitting element 12 is connected thereto by the electrical connections 28 and spaced apart from the heat sink 22 in such a manner that at least one cooling channel 34 is defined between the heat sink 22 and the drive circuitry 30 for the passage in use of a cooling fluid.
