Patent ID: 7838891

Claim:
A light emitting device, comprising: a first substrate; a plurality of electrode layers arranged on the first substrate and spaced apart from one another; and an array of light emitting cells arranged on the electrode layers, the array comprising at least two light emitting cells connected in series with each other by the electrode layers, each of the light emitting cells comprising a first semiconductor layer and a second semiconductor layer, wherein the second semiconductor layer and the first semiconductor layer of each light emitting cell are each coupled to at least one electrode layer, wherein the second semiconductor layer is arranged on the first semiconductor layer and exposes a portion of the first semiconductor layer, wherein one electrode layer couples the first semiconductor layer of a first light emitting cell to the second semiconductor layer of a second light emitting cell, and wherein the light emitting cells comprise first distal ends and second distal ends, the first distal ends face the first substrate, and the second distal ends are opposite the first distal ends, and the second distal ends are separated from each other.
