Abstract:
A method for identifying a short in a first light emitting diode element may include providing a first actuating circuit being a switched-off condition, wherein an output thereof is coupled to a first electrode of the first light emitting diode element, providing a second actuating circuit being a switched-off condition, wherein an output thereof is coupled to a first electrode of a second light emitting diode element and wherein inputs of the first and second actuating circuits, second electrodes of the first and second light emitting diode elements are electrically coupled to a first node, coupling the first electrode of the first light emitting diode element to a first connection of a test energy source, operating the first light emitting diode element in the off-state region using the test energy source, performing a check whether an electric current flows via the first light emitting diode element, and identifying the short.
