Patent ID: 10573784

Abstract:
A micro light emitting diode includes a die-bonding substrate, an adhesive layer, an undoped III-V group semiconductor layer, an N-type III-V group semiconductor layer, a light emitting layer, and a P-type III-V group semiconductor layer. The adhesive layer is disposed on the die-bonding substrate. The undoped III-V group semiconductor layer is disposed on the adhesive layer, and the adhesive layer is between the die-bonding substrate and the undoped III-V group semiconductor layer. The N-type III-V group semiconductor layer is disposed on the undoped III-V group semiconductor layer. The light emitting layer is disposed on the N-type III-V group semiconductor layer. The P-type III-V group semiconductor layer is disposed on the N-type III-V group semiconductor layer, and the light emitting layer is between the N-type III-V group semiconductor layer and the P-type III-V group semiconductor layer.
