Title:
MICRO-LED DEVICE ALIGNMENT, MANUFACTURING METHOD THEREFOR, AND METHOD FOR MANUFACTURING ARRAY MODULE COMPRISING MICRO-LED DEVICES
Document Type and Number:
WIPO Patent Application WO/2022/169087
Kind Code:
A1
Abstract:
The present invention relates to a micro-LED device alignment, a manufacturing method therefor, and a method for manufacturing an array module comprising micro-LED devices, and the micro-LED device alignment according to the present invention comprises: a micro-LED device; a polymer layer formed to encompass the micro-LED device; and a metal layer formed on the polymer layer in the direction of one end portion of the micro-LED device. Therefore, micro-LED devices of an aspect ratio with high light-emitting efficiency can be aligned at a high yield rate by using a dielectrophoretic method.
