1. A method for laser patterning encapsulated organic light emitting diodes comprising:
- providing an encapsulated organic light emitting diode having a light emitting layer, treating 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 energy level of the laser beam is below the ablation threshold of the light emitting layer and any intervening layers, and wherein the light emission of the area(s) of the light emitting layer treated with the laser beam are permanently changed.
