It is presented an organic LED device 101 with, when in use, a predetermined pattern on its light emitting parts. The organic LED device 101 comprises an anode 105, a cathode 103, and an organic light emitting layer 107. The organic light emitting layer 107 is configured to emit light, wherein the organic light emitting layer 107 comprises portion with reduced light emitting properties, the portions of the organic light emitting layer 107 having been irradiated by light with a wavelength in the absorption band of the organic light emitting layer 107, the light intensity being below an ablation threshold of the cathode layer 103, the anode layer 105 and the organic light emitting layer 107 of the organic LED device 101, reducing the light emitting properties of the irradiated portions of the organic light emitting layer 107. It is also presented a method for reducing the light emitting properties of the organic LED device 101.
An organic LED device comprising:
A method for reducing light emitting properties, by means of light, of an organic light emitting layer of an organic LED device, wherein the organic LED device further comprises a cathode layer, an anode layer, and an encapsulating body encapsulating the anode layer, the cathode layer and the organic light emitting layer, the light having a wavelength in an absorption band of the organic light emitting layer, the method comprising the step of:
A method of providing a customer-specific organic LED device, said device including an organic light emitting layer and an encapsulating body that encapsulates the organic light emitting layer, wherein a pattern on the organic LED device is generated on-demand by way of receiving a pattern layout from a customer and in response thereto patterning the organic LED device according to the pattern layout by reducing the light emitting properties of the organic LED device by irradiating desired portions of an organic light emitting layer of the organic LED device through the encapsulating body with laser light, the laser light intensity being below an ablation threshold of the organic light emitting layer of the organic LED device.
A method of providing an organic LED device to a customer, wherein a pattern on the organic LED device is generated on-demand by way of receiving a pattern layout from the customer and in response thereto programming a laser-patterning device, based on the received pattern layout, to execute laser-patterning instructions on the organic LED device, wherein the execution of the laser-patterning instructions involves reducing the light emitting properties of the organic LED device by irradiating at least a portion of an organic light emitting layer of the organic LED device through an encapsulating body that encapsulates the organic light emitting layer with laser light, the laser light intensity being below an ablation threshold of the organic light emitting layer of the organic LED device.
A system for providing a customer-specific organic LED device, comprising:
