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.
