Title:
MICRO LED CHIP INTEGRATED IN ARRAY AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/129361
Kind Code:
A1
Abstract:
A micro LED chip integrated in an array and a manufacturing method therefor. The chip comprises a substrate (1), a conductive connection layer, a thermosetting buffer layer (3) and n light-emitting structures (4), wherein the conductive connection layer comprises a first metal connection layer (21) and a second metal connection layer (22); the first metal connection layer (21) enables first light-emitting micro structures (41) of the same column to form a conductive connection; and the second metal connection layer (22) enables two adjacent second light-emitting micro structures (42) of the same row to form a conductive connection. An integrated array of micro LED chips is formed in a full-common-cathode and double-common-anode manner, thereby improving the transfer efficiency and transfer yield of the chips.
