Abstract
A micro LED display panel includes a substrate, a plurality of first metal electrodes and a plurality of metal pads on a surface of the substrate, a connection layer on the substrate, a plurality of micro LEDs on a side of the connection layer away from the substrate. The connection layer includes conductive particles. Each of the micro LEDs is coupled to at least one of the first metal electrode. A side of each of the metal pads away from the substrate is coupled to some of the conductive particles in the connection layer to form a metal retaining wall. The metal retaining walls enhance structural strength of the micro LED display panel and avoid breakage of any of the micro LEDs.
