OPTOELECTRONIC DEVICE AND PREPARATION METHOD THEREOF, AND ASSEMBLY OF THE OPTOELECTRONIC DEVICE

WIPO Patent Application WO/2021/008438

A1

Provided are an optoelectronic device and a preparation method thereof, and an assembly of the optoelectronic device. Wherein the optoelectronic device comprises: a substrate (100); a plurality of light emitting diodes (200) arranged on the surface of the substrate (100) at intervals, wherein the plurality of light emitting diodes (200) at least comprise a first light emitting diode (210) and optionally comprise a second light emitting diode (220), the first light emitting diode (210) is a hollow structure, so that a containing cavity (211) is formed in the first light emitting diode (210), the containing cavity (211) is provided with an opening (212), at least part of first light emitted by the first light emitting diode (210) is emitted into the containing cavity (211), and the top of the second light emitting diode (220) is suitable for emitting light in the direction away from the substrate (100); and a photoluminescence material layer (300) arranged in the containing cavity (211) of the first light emitting diode (210), wherein the light emitted by the photoluminescence material layer (300) after being excited by the first light is suitable for being emitted in the direction away from the substrate (100) through the opening (212) of the containing cavity (211).
