The invention describes a multi-device OLED (1) comprising a device layer stack (100) comprising a bottom electrode (11), a top electrode (14), at least one inter electrode (13) and plurality of active layers (120, 121), wherein the bottom electrode (11) is applied to a substrate (10), and each active layer (120, 121) is enclosed between two electrodes (11, 13, 14); a current distribution means (500) comprising a current distribution layer (51, 53, 54) for each electrode (11, 13, 14) of the device layer stack (100); a plurality of openings (110, 130) extending from the top electrode (14) into the device layer stack (100), wherein each opening (110, 130) exposes a contact region (111, 131) of an electrode (11, 13); and a plurality of electrical connectors (41, 42), wherein an electrical connector (41, 42) extends into an opening (110, 130) to electrically connect the electrode (11, 13) exposed by that opening (110, 130) to the current distribution layer (53, 54) for that electrode (11, 13). The invention also describes a method of manufacturing such a multi-device OLED. The invention further describes a method of driving such a multi-device OLED, which method comprises applying a voltage across at least one pair (51, 53, 53, 54) of current distribution layers (51, 53, 54) of the current distribution means (500) to stimulate the corresponding active layer (120, 121) of a device of the multi-device OLED (1). |
