Description

technical field

[0001] In various embodiments, a lighting device and a method for producing a lighting device are provided. Background technique

[0002] The printing process has acquired increasing significance in the manufacture of electronic devices. In particular, the printing of substrates for organic light emitting diodes (Organic Light Emitting Diodes) (OLEDs) is an area with high potential for cost reduction and for flexible manufacturing for different OLED designs .

[0003] Conventional OLED substrates have electrical busbars (busbars) and an internal coupling-out layer (internal extraction layer (IEL)) above the substrate. An anode and a cathode are formed above the substrate, with an organic functional layer system between the anode and cathode. The organic functional layer system can have: one or more emitter layers, in which electromagnetic radiation is generated; one or more charge carrier pair generating layer structures, which are composed of two respecti...
