Patent ID: 8878164

Claim:
An organic light-emitting diode having a lossy optical resonator comprising two mirrors, a reflective mirror and a partially reflective and partially penetrable mirror such that a standing wave forms in the resonator and a light beam is able to escape after reflection, and an emitter layer ( 5 ) within the optical resonator, which can generate light by recombination of electrons with holes, wherein the organic light-emitting diode comprises an electron or hole conducting layer ( 4 , 20 , 24 ) which is located within the optical resonator and composed of a photolithographically structurable material located between the two mirrors, the photolithographically structurable material is especially photochemically crosslinkable, or a photoresist which becomes soluble through exposure, and thickness of said electron or hole conducting layer ( 4 , 20 , 24 ) changes.
