    摘要: In at least one embodiment, the method is designed for producing a light-emitting diode display (1). The method comprises the following steps: •A) providing a growth substrate (2); •B) applying a buffer layer (4) directly or indirectly onto a substrate surface (20); •C) producing a plurality of separate growth points (45) on or at the buffer layer (4); •D) producing individual radiation-active islands (5), originating from the growth points (45), wherein the islands (5) each comprise an inorganic semiconductor layer sequence (50) with at least one active zone (55) and have a mean diameter, when viewed from above onto the substrate surface (20), between 50 nm and 20 μm inclusive; and •E) connecting the islands (5) to transistors (6) for electrically controlling the islands (5).

    摘要: The invention relates to an organic light-emitting diode (1000) with an organic layer sequence (100). The organic layer sequence (100) comprises a first organic emitter layer (1) for generating electromagnetic radiation of a first wavelength range (10) and a second organic emitter layer (2) for generating electromagnetic radiation of a second wavelength range (20). A charge carrier generation layer sequence (33), CGL for short, is arranged between the first (1) and the second (2) emitter layer, and the first emitter layer (1) and the second emitter layer (2) are electrically connected in series via said CGL. The CGL (33) additionally has a converter material which converts the radiation of the first (10) and/or the second (20) wavelength range at least partially into radiation of a third wavelength range (30). In this manner, the organic light-emitting diode (1000) can emit mixed light with components of the first (10), second (20), and third (30) wavelength range.
