Abstract
A spherical flip-chip micro-LED, a method for manufacturing the spherical flip-chip micro-LED, and a display panel are provided. The spherical flip-chip micro-LED includes a light-emitting body, a supporting body, a first electrode, a second electrode, and an insulating protective layer. The supporting body is transparent. The first electrode and the second electrode are electrically coupled with the light-emitting body. The insulating protective layer covers the light-emitting body. The light-emitting body, the supporting body, and the insulating protective layer form a spherical structure.
Claims16
A spherical flip-chip micro-LED, comprising:
- a light-emitting body;
- a supporting body being transparent;
- a first electrode and a second electrode which are electrically coupled with the light-emitting body;
- and
- an insulating protective layer covering the light-emitting body, wherein the light-emitting body, the supporting body, and the insulating protective layer form a spherical structure.
A method for manufacturing a spherical flip-chip micro-LED, comprising:
- forming sequentially a light-emitting structure layer and a supporting structure layer on a substrate;
- etching the supporting structure layer to obtain a supporting body, wherein the supporting body is a hemispherical structure and transparent;
- flipping over and stripping the substrate, and etching the light-emitting structure layer into a hemispherical structure;
- perforating the hemispherical structure formed by the light-emitting structure layer to form an electrode accommodating through hole;
- depositing an insulating protective layer which is covered on an outer surface of the light-emitting structure layer and an inner surface of the electrode accommodating through hole;
- etching the insulating protective layer to form an electrode accommodating window;
- and
- depositing a first electrode and a second electrode.
