Abstract
It is presented an organic LED devicewith, when in use, a predetermined pattern on its light emitting parts. The organic LED devicecomprises an anode, a cathode, and an organic light emitting layer. The organic light emitting layeris configured to emit light, wherein the organic light emitting layercomprises portion with reduced light emitting properties, the portions of the organic light emitting layerhaving been irradiated by light with a wavelength in the absorption band of the organic light emitting layer, the light intensity being below an ablation threshold of the cathode layer, the anode layerand the organic light emitting layerof the organic LED device, reducing the light emitting properties of the irradiated portions of the organic light emitting layer. It is also presented a method for reducing the light emitting properties of the organic LED device
