  • Publication number: 20080188156
    Abstract: Structuring electroluminescent organic semiconductor elements can be achieved by providing such an element with a first electrode, a second electrode, and an organic light-emitting layer arranged therebetween. For structuring, areas of the organic layer are selectively destroyed by means of thermal action on the organic layer. The areas destroyed by the thermal action, such as by a laser beam, show no electroluminescence during the operation of the organic semiconductor element. A structuring can thus also be achieved on large-area semiconductor elements in a flexible manner and at low cost.
