Abstract:
A micro LED display and a manufacturing method thereof are disclosed. A plurality of electrode structures is formed on a first surface of a substrate, and a plurality of circuit structure are formed in the substrate, where the circuit structures are electrically connected to the electrode structures. An LED functional layer is formed on the substrate, and includes a plurality of mutually isolated LED functional structures, where the LED functional structures are corresponding and electrically connected to the electrode structures. An electrode layer covers the LED functional layer and is electrically connected to the LED functional structures. Micro lenses are formed on the electrode layer and corresponding to the LED functional structures. Therefore, all the LED functional structures can be wholly used as a light-emitting region of a pixel, improving light emission efficiency of the micro LED display.

Claim (Index 11):
A method of manufacturing a micro LED display, comprising:\n providing a substrate, wherein the substrate is provided with a plurality of chip areas, a plurality of electrode structures are formed on a first surface of the substrate, a plurality of circuit structures are formed in the substrate, and the plurality of circuit structures are electrically connected to the plurality of electrode structures; forming an LED functional material layer on the substrate, wherein the LED functional material layer covers the plurality of chip areas; etching the LED functional material layer to form a plurality of LED functional structures and first openings, each of the first openings running through the LED functional material layer and formed between two adjacent ones of the plurality of LED functional structures; forming isolation structures in the first openings, wherein each of the isolation structures fills a corresponding one of the first openings; covering the plurality of LED functional structures with an electrode layer, wherein the electrode layer also covers the isolation structures; forming a plurality of micro lenses on the electrode layer, wherein the plurality of micro lenses are corresponding to the plurality of LED functional structures; and slicing the plurality of chip areas to form multiple independent chip structures.
