1. A method for laser patterning encapsulated organic light emitting diodes comprising:

  • providing an encapsulated organic light emitting diode having a light emitting layer and an intervening layer, andtreating one or more areas of the light emitting layer with a laser beam, which laser beam energy is transmitted through an electrode layer,wherein the intervening layer comprises a layer between a source of the laser beam and the light emitting layer, and wherein the intervening layer is within the encapsulated organic light emitting diode,wherein the energy level of the laser beam is below the ablation threshold of the light emitting layer and the intervening layer,wherein the laser beam is transmitted through the intervening layer to treat the one or more areas, andwherein the light emission of the one or more areas of the light emitting layer treated with the laser beam are permanently changed.
