Patent ID: 7078070

Claim:
A method for fabricating an organic light emitting diode, comprising: providing a substrate; providing a fixture that is fixed on the substrate over a plurality of depositional sources that can move vertically up and down, including an anode depositional source, an organic emitting layer depositional source and a cathode depositional source, wherein the depositional sources evenly distribute to the substrate moving the anode depositional source up and closer to the substrate to form the anode on the substrate; moving the anode depositional source down before the anode depositional source completes the anode, and moving the organic emitting layer depositional source up slowly to form an organic emitting layer; moving the organic emitting layer depositional source down before the organic emitting layer depositional source completes the organic emitting layer, and moving the cathode depositional source up slowly to form a cathode, wherein heterojunctions between the anode and the organic emitting layer and the cathode and the organic emitting layer are blurred.
