Abstract
Disclosed is an organic light-emitting device operating similarly to a bipolar transistor. The device includes a collector layer including at least one organic light-emitting layer arranged between a first electrode and a second electrode. The first electrode includes a first emitter layer and a first base layer arranged between the first emitter layer and the collector layer, and the second electrode includes a second emitter layer and a second base layer arranged between the second emitter layer. and the collector layer. In case of a display device, the first emitting layer and the first base layer are structured in order to form an array of pixels of first electrodes suitable to be operated separately by an operation unit in a forward bias mode or a reverse bias mode in order to switch light emission of the EL-layer above each pixel on/off.
