Patent ID: 8624274

Claim:
A method for forming a plurality of light-emitting diode pixels arranged in a two-dimensional array, the method comprising: simultaneously forming a plurality of first layers arranged in a two-dimensional array on a first chip substrate by deposition technique; forming a plurality of second layers and a plurality of first light-emitting active layers on the first layers correspondingly; forming a plurality of first intermediate layers on the second layers; forming a plurality of third layers arranged in a two-dimensional array on a second chip substrate; forming a plurality of fourth layers and a plurality of second light-emitting active layers on the third layers correspondingly; placing the third layers, the fourth layers, and the second light-emitting active layers on the first intermediate layers; and forming a plurality of first, a plurality of second, a plurality of third, and a plurality of fourth electrodes coupled with the first, second, third and fourth layers, respectively, wherein the first light-emitting active layer is driven by the first and second electrodes to emit one color of light, and the second light-emitting active layer is driven by the third and fourth electrodes to emit another color of light.
