Abstract

A light-emitting diode device comprises a substrate; a plurality of LED units formed on the substrate, each LED unit including a first semiconductor layer, a second semiconductor layer formed on the first semiconductor layer, and an active layer formed therebetween; and a first sidewall with a length of A microns; and a plurality of conductive connecting structures, spatially separated from each other, wherein one end of the conductive connecting structure are formed on the first sidewall of one of the LED units, and a spacing between two adjacent conductive connecting structures is less than 100 microns; wherein each conductive connecting structure comprises a first extending part formed on one LED unit and a second extending part formed on the adjacent LED unit, wherein lengths of the first and the second extending parts are different; wherein a number of the conductive connecting structures is an integer larger than (A/100)−1.

First claim
