Abstract
The present invention relates to an electroluminescent device () with a light-emitting element () having a capacitance, a switchable current source () being connected to the light-emitting element for providing a driving current to the light-emitting element, and a short detection circuit () for detecting a short in the light-emitting element. The short detection circuit comprises a triggerable voltage determining unit () for determining, upon being triggered, a voltage across the light-emitting element, a triggering unit () for triggering the triggerable voltage determining unit to determine the voltage across the light-emitting element after a time period (At) during which the driving current is not provided to the light-emitting element, and a short detection unit () for detecting a short in the light-emitting element based on the determined voltage across the light-emitting element. Therewith, the detection can be less sensitive with respect to production tolerances and the like.
