Patent ID: 8022421

Claim:
A light emitting module comprising: a substrate; and a plurality of LED pixels arranged in a two-dimensional array, wherein each of the LED pixels comprises: a first layer formed on the substrate by deposition technique; a first light-emitting active layer on the first layer, wherein a portion of a surface of the first layer is exposed by the first light-emitting active layer; a second layer on the first light-emitting active layer; an intermediate layer on the second layer, wherein a portion of a surface of the second layer is exposed by the intermediate layer; a third layer on the intermediate layer; a second light-emitting active layer on the third layer, wherein a portion of a surface of the third layer is exposed by the second light-emitting active layer; a fourth layer on the second light-emitting active layer; and first, second, third, and fourth electrode pads respectively formed on the exposed portions of surfaces of the first layer, the second layer, and the third layer and a surface of the fourth layer, wherein the first light-emitting active layer is driven by the first and second pads to emit one color of light, and the second light-emitting active layer is driven by the third and fourth pads to emit another color of light.
