LED structure and manufacturing method thereof

The invention provides an LED structure and a manufacturing method thereof. A plurality of first graph structures in periodic array configuration are formed in a graphic substrate of the LED structure, the surface of the original substrate is divided into a plurality of areas in periodic array configuration through the first graphic structures, independent light-emitting semiconductor layers are subjected to insulation separation through the graphic substrate during formation, manufacturing of an isolation groove through the lithography etching technology at the chip manufacturing end is omitted, filling of the isolation groove with insulating materials is not needed, first electrodes and second electrodes of independent light-emitting semiconductors are electrically connected as required at same time when the first electrodes and the second electrodes of the independent light-emitting semiconductors are formed, a cascaded structure of an optional number of particles is formed, the independent light-emitting semiconductor layers forming the cascaded structure do not need to be recut, independent packaging of the independent light-emitting semiconductors is subsequentially not needed.
