Abstract
The invention relates to an organic light emitting diode device having an electrode sheet of a light emitting area and an electrode contact in contact with the electrode sheet, to a method for forming such OLED device and to method of operating such OLED device. In order to provide such OLED device having a reduced tendency for the occurrence of hot spots, the present invention provides for reducing a local and/or average regional current density of a current flowing in operation of the lighting device through an interface between the electrode sheet and the electrode contact in a corner area of the interface.
