Patent ID: 7012281

Claim:
A light emitting diode device, comprising: a substrate deposited on a bottom of the light emitting diode device; a semiconductor layer formed above the substrate including an n-type semiconductor layer, an active layer and a p-type semiconductor layer, wherein the active layer is formed between the n-type semiconductor layer and the p-type semiconductor layer; a matrix-lines layer formed on the p-type semiconductor layer, wherein the matrix-lines layer is divided into a plurality of regions for providing uniformly spreading current on the light emitting diode device; and a light-transmission conductive layer that is an oxide layer filled on the matrix-lines layer so as to effectively increase optical transmission of the light emitting diode device; wherein an occupied area of the matrix-lines layer follows a formula a <(1 −T T /T I ) A where a is the matrix-lines layer occupied area, A if the area of the light emitting diode, T T is the transparency of the matrix-lines layer, and T I is the transparency of the light-transmission conductive layer.
