Document Type and Number:
WIPO Patent Application WO/2021/196556
Kind Code:
A1
Abstract:
Provided are a light-emitting diode device and a manufacturing method therefor, and a display panel. The micro light-emitting diode device comprises: a plurality of light-emitting units, wherein each of the light-emitting units comprises a first semiconductor layer, a second semiconductor layer and a multi-quantum-well layer; common electrode layers of a grid shape; a plurality of driving electrodes; and at least one superstructure layer, wherein the superstructure layer is located at a light-emitting display side of each of the light-emitting units; each superstructure layer comprises a plurality of superstructure units; the superstructure units in the same superstructure layer correspond to the light-emitting units on a one-to-one basis; each of the superstructure units is provided with a plurality of recess structures or a plurality of protrusion structures; and the superstructure units are configured to change the light intensity distribution characteristic of light emergent from the light-emitting units.
